High temperature shift
WebIn the first stage, a high-temperature shift (HTS) is performed at 300–450 °C, followed by a low-temperature shift (LTS) reaction operated at 180–230 °C [64]. Industrial catalysts for HTS and LTS stages are Fe 2 O 3 promoted with Cr 2 O 3 and Cu on ZnO/Al 2 O 3, respectively [10,24,65].

WebThe first, at high temperature, is called “HTS” for “high temperature shift” with a catalyst in general Fe2O3-Cr2O3. The gas cools, enters at 350°C and leaves at 400-450°C. For a … 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.
