| Abstract: | The properties of adsorption of water vapor on iron oxide containing CeO 2 have been studied by pulse gas chromatography(GC) with the method of retention volume It was found that the adsorption heat of water vapor on the catalyst decreased and the number of adsorption centers did not change as the amount of cerium oxide increasing in the samples However, the adsorption heat increased somewhat as the sample contains enough amount of cerium oxide The activities of the samples catalyzing the water gas shift(WGS) reaction were measured The results showed that the lower the adsorption heat of a sample was, the higher its activity became It was proved that cerium oxide was a catalyst accelerator in the WGS catalysis |
