Mesoporous silica-aluminas were studied as supports of Pd-Pt catalysts in HDS of 4,6-DMDBT at 300oC and 5 MPa. HYD was the exclusive route of HDS and most of HDS activities correlated with Brønsted acidities of catalysts. Pd-Pt catalysts at the lowest loadings around 0.10 wt.% were still 5 time more active than CoMo/Al2O3.
