Abstract

The CoMo/Al₂O₃ catalysts with different metal loading were studied by low temperature in situ FT-IR using CO as probe molecule which appears to be a powerful method by giving rise to signals specific for unpromoted and promoted Mo sites. The result revealed that the increase of CoMoS phase on the catalyst surface improves the HDS activity and selectivity. The ratio of active site number of CoMoS and MoS₂ correlates linearly with HDS selectivity, which provides an effective tool for developing industrial selective HDS catalysts.
