The characteristics of a water gas shift reaction (WGSR) in association with carbon dioxide sequestration under the effects of a high-temperature catalyst (HTC) and a low-temperature catalyst (LTC) are studied experimentally. With the condition of fixed residence time (0.1 s) for the reactants in the catalyst bed, it is found that the reaction behaviors with the HTC are inherently different from those with the LTC. Specifically, for the WGSR with the HTC, the reaction can be divided into a rapid growth regime, a progressive growth regime and a slow growth regime with increasing reaction temperature or steam/CO ratio. With regard …
