Sour shift for SNG

Johnson Matthey is the world’s leading supplier of sour shift catalysts with the KATALCO K8-11 series of products used downstream of all major gasification technologies.  The catalysts are based on cobalt and molybdenum sulphides as the active components and are particularly robust to withstand sharp temperature changes, high steam partial pressure and possible contamination from impurities in the raw gas.

For large plants we are able to offer proprietary reactor internals so the gas flows radially through the catalyst.  This gives a much shorter flowpath and lower gas velocities and hence a much lower pressure drop than conventional axial designs.  The radial reactor technology also allows smaller diameter vessels and lower design temperatures to be used so lowering the cost of the reactor shell.

Our range of sour shift catalysts includes:
