	1	Effect of Addition Sequence during Neutralization and Precipitation on Iron-based Catalysts for High Temperature Shift Reaction显示文摘The preparation of the iron-based catalysts promoted by cobalt with a small amount of copper and aluminum for the high temperature shift reaction(HTS)with different sequences of adding catalyst raw materials during neutralization and precipitation was investigated.XRD,BET and particle size distribution(PSD)were used to characterize the prepared catalysts.It was found that the catalyst crystals were allγ-Fe 2 O3,and the intermediate of the catalyst after aging was Fe3O4.The crystallographic form of the catalyst and its intermediate was not affected by the addition sequence in the neutralization and precipitation process.The results showed that the specific surface area and the particle size of the catalysts depended on the addition sequence to the mother liquor. Cobalt with a small amount of copper and aluminum could increase the specific surface area and decrease the particle size of catalysts.
