Webproducts at lower temperatures, the reaction kinetics are faster at elevated temperatures. For this reason, the catalytic water-gas shift reaction is initially carried out in a high-temperature shift (HTS) reactor at 350-370°C. Conversion in the HTS reactor is limited by the equilibrium composition at the high temperature.
