The influence of the acidity of ultrastable Y (USY) zeolite‐supported tungsten or nickel sulfide catalysts, prepared at different pH values, on thiophene hydrodesulfurization activity has been studied. The acidity affects the catalysts' deactivation. The results of the initial activity clearly show a synergic effect between the metal sulfide centers and the Brønsted acid sites present in the zeolites. © 1998 SCI
