A real support effect on the activity of fully sulphided CoMoS for the hydrodesulphurization of thiophene

It is shown that on Al2O3, SiO2, and C, a fully sulphided CoMoS phase can be prepared with similar degrees of dispersion, and that the specific activity of this phase for the hydrodesulphurization of thiophene is higher when this phase is supported on carbon than when it is supported on alumina or silica.
