WebSince the low temperature shift catalyst is relatively expensive, the optimum CO conversion is to take about 90% conversion over the high temperature shift catalyst followed then by a low temperature shift conversion for the remainder (B-3). 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. smart airbnb home https://aweb2see.com
