The inร‘uence of the acidity of ultrastable Y (USY) zeolite-supported tungsten or nickel sulรde catalysts, prepared at di โ€ erent pH values, on thiophene hydrodesulfurization activity has been studied. The acidity a โ€ ects the catalystsร deactivation. The results of the initial activity clearly show a
