Water-gas-shift-catalysts
Water gas shift catalysts
The water gas shift reaction converts carbon monoxide and water to carbon dioxide and hydrogen. The reaction is catalysed by a number of different base metal catalysts, depending on the operating temperature and levels of poisons in the feedstock.
KATALCOTM shift catalysts are synonymous with simplicity in their installation and operation, reliability in service and sustainability.
High temperature shift
Based on an iron-chrome formulation, our latest high activity catalysts for high temperature shift operations are the result of extensive catalyst developments. They allow lower volumes of catalyst to be installed and increase the options for plant optimization.

Low temperature shift
Johnson Matthey offers a range of low temperature shift catalysts utilising copper and zinc on alumina. These provide low methanol by-product formation by combining high activity and poisons resistance with excellent selectivity.

Isothermal and medium temperature shift
Our range of medium temperature shift and isothermal shift catalysts are designed to be more thermally stable and manage the exotherm under low steam to carbon conditions, thus improving the efficiency of hydrogen production.
Sour shift
Johnson Matthey is the world’s leading supplier of sour shift catalysts. Our KATALCO K8-11 series are designed to be robust and can withstand sharp temperature changes, high steam partial pressures and the effect of contamination from impurities in raw gas.
