    HDS on Pd-Pt catalysts proceeded almost exclusively by the hydrogenation (HYD) route. Activities of majority of Pd-Pt catalysts correlated with their Brønsted acidities while not with metal dispersion2. The studied sulfidic CoMo phase increased DDS route (formation of DMBP) and results in similar HDS/HDO activity and selectivity (kEB/kHC) as the reference Al2O3 supported counterpart. We believe that high acidity of MSAs positively influence hydrorafination of 4,6-DMDBT and oxygen (OA) containing feeds, which motivate our forthcoming research.
