| Abstract: | The effect of support (SiO2-Al2O3, Al2O3,MgO) of the Rh-Mo(S) sulfide catalysts on the synergy in hydrodesulfurization (HDS) of thiophene and hydrodenitrogenation
(HDN) of pyridine was studied. The synergy in HDS was between 7–10 regardless of the kind of support used. The synergy in
HDN varied from none over the MgO supported sample to about 3 over SiO2-Al2O3 supported catalyst, in accord with the positive effect of increasing support acidities.
