摘要

•Higher activity of HDS and HYD activities of the gasoline model feed in the presence of nickel and cobalt as promoter.•Strong inhibiting effect induced by CO only with CoMoS/Al2O3.•Higher adsorption energy of CO on CoMoS/Al2O3.•NiMoS and MoS2, almost unsensitive to CO for HDS and hydrogenation reactions.•No selectivity modification in presence of CO.
