Abstract

The active sites of sulfided CoMo/Al₂O₃ catalyst were studied by in situ FT-IR of adsorbed CO, and the results were correlated with evaluation results of HDS activity and selectivity. The ratio of active site number of MoS₂ and CoMoS correlated linearly with HDS selectivity. The increase of relative content of CoMoS phase on the catalyst surface improved the HDS activity and selectivity. The strong electron deficient properties of CoMoS active sites were the main reason of its excellent HDS activity and selectivity.
