Silica-alumina (MSA) was modified by acid leaching and used as support of Pd and Pd-Pt catalysts. The leaching decreased the Al2O3 content from 52 to 9 wt.% and increased Brønsted acidity and BET surface area. This improved activities of Pd catalysts in HDS of thiophene and benzothiophene. The bimetallic Pd-Pt catalyst prepared from Pd acetate and Pt(NH3)4(OH)2 showed significant promotional effect in HDS.
