High temperature shift
WebThe water-gas shift (WGS) reaction is an equilibrium-limited reaction at higher temperatures, usually kinetically limited below 250 °C. This requires development of more active low-temperature catalysts and advanced reactor concepts to overcome limitations related to low CO conversions in the range 250–350 °C.
