KATALCO a commitment to excellence The world relies on ammonia derived fertilisers for food production so manufacturing these as efficiently as possible is of critical importance. While commercial ammonia production can be traced back more than 100 years, the ammonia process as we know it today was initially developed in the 1960s. Since that time, Johnson Matthey (formally as ICI) has invested enormous resources in research and development to ensure that ammonia catalysts have been adapted to meet your needs. KATALCOTM ammonia plant catalysts are more active, more selective and more robust to...

In addition, through our range of PURASPEC TM catalysts and absorbents,...

By using KATALCO 33-1, the total catalyst volume can be reduced while still achieving the required life. Further savings are also realised from much easier loading and discharge, and no requirement for pre‑sulphiding of the HDS catalyst or reduction of the ultrapurification catalyst.

Pre-reforming CRG LHR Pre-reforming catalyst CRG LHCR Pre-reforming catalyst JM has been associated with pre‑reforming technology since the 1960s and offers the CRG series of catalysts which have been demonstrated to be the most active and robust commercially available products. CRG LHR is a precipitated catalyst with nickel as the active component. The catalyst is supplied in the pre‑reduced and stabilised form. The oxidised 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...

CRG pre-reforming technology delivered increased production and lower energy consumption on a conventional Kellogg ammonia plant. In a retrofit to a 1000 mtpd ammonia plant JM offered pre-reforming technology, including 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 computational fluid dynamics (CFD), to assess the duty across a new pre-reformer reheat coil which needed to be installed within an existing convection section, on a 90° bend in the fluegas duct. JM CFD modelling...

Secondary reforming KATALCO 23-8 SERIES Nickel oxide on alpha alumina KATALCO 54-4 SERIES Nickel oxide on calcium aluminate KATALCO 89-6 SERIES PGM on proprietary ceramic support The mechanical and physical requirements of a secondary reformer are the most arduous in the plant. JM combines sophisticated CFD techniques and process modelling, calibrated against data generated in our reforming pilot plant, to ensure the best performance from our state of the art range of catalysts. Johnson Matthey can also offer secondary reformer technology including proven burner designs. KATALCO 23-8 series is...

The performance of a secondary 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. JM has expertise including the KATALCO high intensity ring burner offering efficient combustion and mixing in a reliable design. We have also combined our catalysis, CFD and mechanical design skills to resolve secondary reformer and transfer main “hot spot” problems. An example of this is delivering improved plant reliability to secondary reformers which have suffered from...

High temperature shift KATALCO 71-5/71-6 High temperature shift catalyst KATALCO 71-5M/71-6M High temperature shift catalyst KATALCO 71-5F Shape optimised high temperature shift catalyst The KATALCO 71-5 range of high temperature shift catalysts offers high activity due to the inclusion of a patented structural promoter which improves the pore size distribution. This increases activity by reducing the diffusional limitation associated with many high temperature shift catalysts. It’s pore structure also allows better water vapour release during drying after any wetting incident. The latest edition...
