摘要：

The uptake of sulfur reduces the overall activity of PtMo/Al2O3 and enhances that of CoMo/Al2O3 in conversion of cyclohexanol. Significant changes in selectivity indicate the existence of different active sites of the initial catalyst for hydro-dehydrogenation and dehydration. The differences in catalytic activity expressed in terms of overall TOF decrease with increasing sulfur treatment like for Ru and Ir promoted catalysts.
