KATALCOJM a commitment to excellence For many years, methanol has been used primarily as a chemical intermediate in manufacturing plastics and resins, then more recently in the manufacture of methyl tertiary butyl ether (MTBE). However, now methanol is being seen as a product that can be introduced directly into the gasoline pool by blending. This allows indigenous resources to be used and provides a diversity of supply that can help to reduce dependence on crude oil. The methanol industry as we know it today is based almost entirely around the technology and catalysts developed and commercialized by ICI in the late 1960s. Since that time, Johnson Matthey Catalysts (having acquired the ICI catalyst business and then Davy Process Technology) has invested enormous resources in R&D to ensure that the technology has adapted to meet our customers’ needs. KATALCOJMTM methanol catalysts are more active, more selective and more robust, to give you the highest plant rates, longest run time and the best value for money. The selection of catalyst and technology is just the start of the process. We seek to develop close working relationships with all users of our catalysts to gain a good understanding of your operations. This allows our engineers to provide the best advice on the operation of the catalysts within the methanol process.
Within the methanol industry, Johnson Matthey Catalysts is seen as the world leader with the greatest depth and breadth of knowledge. This position has been developed through a combination of its own technology and catalyst development efforts alongside the experience gained from the large number of plants that use them. It has been further underpinned by operating experience in the methanol plants formerly operated by ICI, which ensures that Johnson Matthey Catalysts understands your needs as a plant operator better than any other catalyst or technology provider. Our focus is on delivering the best plant performance in the world. We have on-going development programmes producing new and better catalysts and improving the process technology for the me thanol industry. Our applications know-how and services enable the best performance to be achieved from these products. The overall impact of Johnson Matthey’s new catalysts and technology can be to improve methanol plant costs by millions of dollars every year.

Johnson Matthey Catalysts offers our range of KATALCOJM purification absorbents and catalysts, which ensures optimized systems for meeting individual plant requirements. In addition through our range of PURASPECJMTM catalysts and absorbents we can provide mercury removal down to ppb levels, low temperature H2S removal absorbents and ultrapurification down to ppb levels of sulphur to protect even the most sensitive of downstream catalysts, including prereforming and methanol synthesis catalysts. For methanol plants using a coal feedstock and gasification technology, we can again offer KATALCOJM and PURAPECJM purification solutions to remove impurities such as chloride and sulphur after the RECTISOLTM or SELEXOLTM acid gas removal system, upstream of methanol synthesis.
KATALCOJM 33-1 is the latest addition to our purification range. It is a 3-in-1 total sulphur removal product, which combines the functionality of organic sulphur conversion, high capacity sulphur removal, and low level sulphur polishing (ultrapurification) in a single product. The versatility of KATALCOJM 33-1 allows it to be deployed in methanol plants in numerous ways, as a single product or in conjunction with conventional purification products.
Further savings are also realised from the much easier loading and discharging, no requirement for pre-sulphiding of the HDS catalyst or reduction of the ultrapurification catalyst.

Pre-forming catalysts CRG LHR
CRG LHCR
Johnson Matthey Catalysts has bee n associated with pre-reforming catalysts since the 1960s and together with Davy Process Technology offers the CRG series of catalysts which have been demonstrated to be the most active and robust commercially available products. In methanol plants, operating on natural gas feeds, the use of high pre-reformer inlet temperatures allows the maximum amount of heat recovery from the steam reformer flue duct giving an economic benefit through improved thermal efficiency of the process. In addition, by transferring the maximum amount of reforming duty into the pre-reformer, the size of the primary reformer is reduced which results in a lower capital cost.
CRG LHR is a precipitated catalyst with nickel as the active component. The catalyst is supplied in the pre-reduced and stabilized form. The oxidized form, CRG LH, is available as a special order. CRG LHR pre-reforming catalyst is specially formulated to deliver good performance at high pre-reformer inlet temperatures (>500°C), which cannot be attained with many other catalysts. This allows the maximum amount of heat recovery from the steam reformer flue duct and hence increases the economic benefits that can be obtained from the pre-reformer.
CRG LHR is available in two distinctive shapes. The exceptionally high geometric sur face area that is produced by the small standard cylindrical pellet delivers outstanding catalytic activity and allows the construction of relatively small pre-reforming reactors. However, where pressure drop must be minimized, the unique microcloverleaf shape, CRG LHCR provides low pressure drop characteristics in combination with high pre-reforming activity.
Johnson Matthey Catalysts offered the most effective combination of CRG LHCR catalyst supply and engineering capability to deliver a 15% increase in capacity and a 5% reduction in energy consumption. An element of engineering capability used was CFD, as the new pre-reformer reheat coil needed to be installed within an existing convection section, adjacent to a 90° bend in the fluegas duct. Johnson Matthey CFD modelling quickly showed that the coil would work as designed.

Nickel oxide on alpha alumina
KATALCOJM 57-4 series
Nickel oxide on calcium aluminate
KATALCOJM 25-4 series
Lightly alkalized version of 57-4 series
In this critical operating unit in the methanol production train, the KATALCOJM combination of catalysts and services ensures optimal operation at all times. KATALCOJM catalysts are unique with the ability to reform efficiently the full range of feedstocks from light natural gases and refinery off-gases right up to naphthas. Our QUADRALOBETM catalyst range employs a carefully designed shaped support offering high surface area and high voidage with excellent heat transfer performance. The resulting high activity, heat transfer and low pressure drop gives a combination of lower methane slip, high throughput and longer tube lives for methanol plant reformers. Johnson Matthey manufactures three main catalysts for use in steam reformers using a natural gas feedstock:
KATALCOJM 25-series, 23-series and 57-series catalysts. Johnson Matthey reforming catalysts are made in a range of sizes, allowing optimum reformer loading for each individual plant.
KATALCOJM 25-series: This is a lightly alkalized nickel oxide on a calcium aluminate support. The alkali prevents carbon formation in the upper part of highly stressed reformers where the heat fluxes are high and especially when the feedstock contains heavier hydrocarbons, while retaining the high activity of gas reforming catalysts. KATALCOJM 23-series: This catalyst is nickel oxide on an alpha alumina support. KATALCOJM 57-series: This catalyst is nickel oxide on a calcium aluminate support. Selecting the right catalyst for your application is essential for good reformer performance. Johnson Matthey Catalysts will make detailed recommendations based upon your individual operating conditions ensuring reliable optimal performance of your reformer. For naphtha feedstocks Johnson Matthey also manufactures KATALCOJM 46-series.

This is typically used for: • revamp studies and revamp implementation • re-tube studies • reformer surveys • operational audits. Results are immediately available allowing rapid assessment of variations in conditions. Other reforming services from Johnson Matthey Catalysts include: • UNIDENSETM reformer loading technique • LOTIS TM laser optical tube inspection system • reformer surveys and operational audits • catalyst tube temperature measurement • managing the life cycle of reformer catalyst tubes • reformer consultancy • pressure drop measurement • combustion systems advice.
Autothermal reforming KATALCOJM 23-8 series KATALCOJM 28-4 series KATALCOJM 54-8 series
The mechanical and physical requirements of an oxygen blown secondary are the most arduous in the plant. Johnson Matthey Catalysts combines sophisticated Computational Fluid Dynamic techniques and process modelling, calibrated against data generated from its Syngas Generation (SGG) pilot plant, to ensure the best performance from its state of the art range of catalysts. Johnson Matthey Catalysts and Davy Process Technology offer reactor technology including a proven burner design.
KATALCOJM 23-series and 28-series is nickel on alumina catalyst which gives you high stability and high activity, KATALCOJM 54-8 series is nickel on calcium aluminate. These catalysts give you high stability and high activity allowing Johnson Matthey to offer you the best mix of activity, pressure drop and high temperature stability for your application.
KATALCOJM 89-6 is a catalyst designed for use in the top of autothermal reformers where the temperature and steam partial pressure is high, a combination that can lead to unacceptably fast volatilisation of alumina and the problems associated with this and its subsequent condensation. This catalyst utilizes a refractory metal as the active component on a stabilized high temperature ceramic support.
Autothermal reformer services The performance of an autothermal reformer is related not just to the catalyst performance but also the burner and the mixing space above the catalyst bed as well as the integrity of the refractory lining system of the reformer. We have the right combination of expertise and practical experience to help our customers determine the cause of any under performance and develop reliable systems. We have also combined our catalysis, CFD and mechanical design skills to resolve autothermal reformer and transfer main “hot spot” problems. An example of this is our delivering improved plant reliability to autothermal reformers which have suffered from increased pressure drop due to ruby formation, leading to hot spots. Our understanding of the issue allowed us to apply leading catalysts such as KATALCOJM 89-6Q to solve the problems eliminating ruby formation and pressure drop increase.
Ruby formation
Sour shift KATALCOJM K8-11 KATALCOJM K8-11 HA
The production of syngas using gasification or par tial oxidation differs considerably from that using catalytic steam reforming. Depending on the feed and process configuration, the raw syngas will have a high CO content and, it is likely that it will also have high sulphur content. This gas needs to be shifted and the excess CO 2 removed to achieve the desired hydrogen to carbon oxides ratio, and it will require the use of a sulphur tolerant shift catalyst. Johnson Matthey Catalysts is the world’s leading supplier of sour shift catalysts with the KATALCOJM K8-11 series of products. These catalysts are particularly robust and can withstand sharp temperature changes, high steam partial pressure and the effect of contamination from impurities in the raw gas. The standard catalyst for sour shift is KATALCOJM K8-11, which has been well proven in methanol applications downstream of several different types of gasifier. Other variants of this standard catalyst are available to meet specific client requirements which may place greater emphasis on pressure drop or low-temperature activity. An example of this is KATALCOJM K8-11HA which uses a geometric shape with higher external surface but which creates a higher packed voidage and thus a lower pressure drop.
Johnson Matthey’s experience in the application of sour shift catalyst downstream of gasifiers puts us in an ideal position to provide advice on the optimum system configuration, including the appropriate number of reaction stages, the use of bypasses, steam requirements and heat recovery options. For instance, at large plant capacities, the use of radial flow reactors may allow the use of a single reactor instead of multiple parallel axial reactors, so reducing installed plant cost. Johnson Matthey Catalysts is able to provide a sour shift catalyst customised for radial flow applications (KATALCOJM K8-11R) along with proven designs of internals for radial flow reactors.
applications means optimum system configurations for our customers.
Methanol synthesis catalysts KATALCOJM 51-7 KATALCOJM 51-8 KATALCOJM 51-8PPT KATALCOJM 51-9 KATALCOJM 51-9S
The KATALCOJM 51-series of catalysts is key to the methanol technologies offered by Johnson Matthey and Davy Process Technology. KATALCOJM 51-1 and the LPM process revolutionised synthetic methanol production in the 1960s and have provided the majority of the world’s production ever since that time. These technologies currently account for an annual production capacity of over 30 million tonnes of methanol.
KATALCOJM 51-1 was the first three-component methanol synthesis catalyst comprising zinc oxide and alumina as the support with copper as t he active catalytic component. Successive generations of KATALCOJM 51-series catalysts have been developed to give increasing activity, selectivity and stability, so ensuring ever more efficient operation whatever the source of syngas.
The latest in this series, KATALCOJM 51-9S, is particularly suited to highly stressed duties with its activity, strength and selectivity. The high activity and stability of KATALCOJM 51-series catalysts means that typically a charge lasts between four and six years, but some charges have been in operation for more than 8 years. Their strength enables them to withstand the rigors of this extended operation and as a result they show little change in pressure drop and are easily discharged at the end of life.
KATALCOJM APICO methanol synthesis KATALCOJM APICO 51-100
Ever since ICI turned synthetic methanol manufacture on its head with the introduction the first copper-based methanol synthesis catalyst and the LPM process, catalysts have continued to develop organically. Until now that is. Johnson Matthey has introduced its new methanol synthesis catalyst, the KATALCOJM APICO TM range, which represents the biggest single leap forward; bigger than the sum of al l the incremental improvements over the last 40 years.

M5000 reformer
•
Steam methane reformers (SMRs) While this technology has been around for a long time, conventional SMRs have been undergoing a continual process of improvement. The largest methanol plant in the world based on natural gas is the Methanol Holdings (Trinidad) Limited M5000 plant. Based on LPM technology, this plant started up in 2005, produces 5,000 tpd of methanol from a single SMR, and represents the benchmark for future technology development in this field.
•
Autothermal reformers (ATR) Johnson Matthey Catalysts’ 30+ years of experience was gained on air and oxygen blown ATRs including the Coogee LCM plant in Australia. Our unique design of ATR has proven its reliability and durability over many years in both oxygen and air fired service. All elements from the burner and distribution system, through to the refractory lining, catalyst and refractory support arch, deliver long term trouble-free performance.

•
Combined reforming Combined reforming incorporates the steam methane reforming process and the ATR. The technology is particularly applicable for use on large capacity plants using light natural gas. Two versions of this concept have quite different features. Combined reforming with SMR Combined reforming with an SMR is a way of getting beyond the limitations imposed on plant capacity by the SMR alone. Around 40% of the reforming duty is carried out by the SMR, while the balance is carried out in the ATR. This combination of steam and autothermal reforming can yield an ideal stoichiometric gas for methanol production. The technology stretches the maximum capacity upwards, with capacities in excess of 10,000 tpd being possible with a single SMR the size of the M5000 reformer and a single ATR.
in 1994 (the Coogee LCM plant). To date, there is over 50 operating years of experience in four industrial scale units. Used in a combined reforming process the outlet from an ATR feeds the shell side of the GHR and is forced to flow counter-currently to the feed natural gas and steam flowing inside the tubes. It is the most energy efficient process available with the lowest CO 2 emissions and water make up rate.

•
Combined reforming with Gas heated reforming (GHR) The GHR is a heat exchanger with catalyst inside the tubes and was originally developed by ICI in the 1980s for use in the ammonia industry, with three units coming into operation followed by the first methanol application
Like the Compact Reformer, the GHR generates little steam and decouples the power system from the process, so plant designers can choose something other than steam turbines to drive rotating equipment. The use of gas turbines, for example, can give further efficiency benefit s, reducing gas consumption and CO 2 emissions.
•
Compact Reformer The Compact Reformer is similar to a conventional reformer in that the chemistry is the same, but the primary heat transfer mechanism is by convection rather than radiation. However, this device significantly increases the process intensity. The Compact Reformer is a preassemble modular device that is less than a quarter of the weight and size of a conventional reformer. The technology is particularly suited to offshore use or remote locations where transportation and/or site construction are difficult.
Coal gasification Coal gasification is an established technology which, in combination with sour shift, acid gas removal and syngas purification, can be readily used to generate syngas for methanol synthesis. Johnson Matthey Catalysts and Davy Process Technology have catalysts and technologies in sour shift, purification and, of course, methanol synthesis and distillation, and can work with the licensors of the gasification technologies to deliver an integrated coal to methanol production facility
Leading edge methanol technologies Johnson Matthey Catalysts and Davy Process Technology Methanol synthesis technologies A number of reactor designs and synthesis flowsheet arrangements for methanol production can be utilized. •
Tube cooled converter The tube cooled converter is a simple reactor which uses the feed gas to the reactor to control the temperatures in the catalyst bed. Fresh feed gas enters at the bottom of the reactor and is preheated as it flows upwards through tubes in the catalyst bed. The heated feed gas leaves the top of the tubes and flows down through the catalyst bed where the reaction takes place. The heat of reaction is removed by counter-current exchange with feed gas which results in a temperature profile that approximates to the maximum rate curve. Operated in this manner the reactor achieves good catalyst utilization.
•
Radial flow steam raising converter This steam raising converter is a radial flow reactor with catalyst outside and steam inside the tubes. In the DPT design, fresh feed gas enters at the bottom of the reactor and into a central perforated-wall distributor pipe. The gas then flows radially out through the catalyst bed. Water from a steam drum enters at the bottom of the vessel, and flows upwards through the tubes where it is partially vaporized, removing the heat generated by the reaction before returning to the steam drum. The reaction temperature is controlled by varying the steam pressure inside tubes embedded in the catalyst bed.
Shenhua methanol synthesis
•
Axial flow steam raising converter The axial flow steam raising converter is a different design in which the catalyst is contained within the tubes with boiling water on the outside. As for the radial reactor, the reaction temperature is controlled by varying the steam pressure. This arrangement gives excellent cooling of the catalyst bed and allows steam to be generated at the maximum possible pressure without overheating the catalyst. The reactor does however require thick tube sheets that limits the maximum capacity of the reactor to around 1,500 tpd and requires a large number of tubes to accommodate that catalyst. This tends to limit the use of this type of reactor to those applications where its high heat transfer performance is required, e.g., in certain coal gasification based flowsheets.
Distillation technologies Dependent on the grade of methanol required, there are different options for methanol distillation. To produce DME or MTO-grade methanol, only a single column is required to remove the dissolved gases and some of t he light byproducts. To produce refined methanol for chemical or fuel usage, for example Federal AA and IMPCA grade methanol, a two or three column refining system is used. The threecolumn system uses the least heat so is preferred where energy costs are high or the heat for distillation is not readily available.

Further development The acquisition of Davy Process Technology by Johnson Matthey has created a unique environment in which it has been possible enhance the intimate interaction of catalysts and technology development. We continue to drive the improvement of our processes and to develop new ones that will continue to lower the installed cost, improve efficiency to make better use of the natural resources and minimize the impact on the environment. It is also important that catalyst and new technology developments keep pace with one another to ensure that the process can operate at its optimum efficiency and maintain or increase the time between plant turnarounds.
Product realisation: From the laboratory to the plant Catalysts and processes are developed in laboratory reactors, semi-technical units and side-stream reactors specifically designed to simulate accurately the important features of operation in full scale plants. The catalysts are then finally proven at commercial scale before being incorporated into the Johnson Matthey Catalysts KATALCOJM and PURASPECJM sales range.
research, technology and engineering centre at Billingham, UK, benefit directly from the close interaction of chemists and physicists with engineers who have plant operations experience. There is close co-operation between the teams involved in fundamental research, catalyst development, catalyst manufacture, and synthesis gas production. Catalyst development is supported by the most modern techniques in applied surface science. Our new improved catalysts go through a range of validation testing and small scale manufacturing runs as part of the commercialisation process. This ensures that the catalyst we make in the lab is exactly the same as the one supplied from full scale production. At every point along this process the key performance parameters of the catalyst are tested in our dedicated catalyst testing facilities in Billingham, UK. This guarantees that the benefits we see in small scale testing are transferred to the customers operating unit.
New catalysts continue to deliver significant plant improvements. Every catalyst activity improvement enables a corresponding potential increase in plant rate, and can also deliver a longer life before current end of run conditions are achieved. Lower pressure drop options enable plant rate and efficiency improvements. For steam reforming catalysts, improved heat transfer reduces the temperature of reformer tubes, extending the time between costly renewal. Better poison pick-ups extend absorbent lives and improve the performance of downstream catalysts. Johnson Matthey Catalysts has teams focusing on the catalysts for each plant reactor and targeting performance improvements driven by customers’ requirements. Each area has a dedicated team of experienced scientists. Research and development activities in Johnson Matthey’s catalysis
