This paper reports on the effects of a synthetic modified zeolite, mordenite, on the activity of alumina-cobalt-molybdenum (ACM) and alumina-nickel-molybdenum (ANM) catalysts Tests on the hydrogenolysis of thiophene were performed in a continuous-flow laboratory unit, and tests on the hydrodesulfurization of diesel fueld were performed in a pilot unit. The catalysts with the modified zeolite proved to be more active than the commercial ACM catalyst in the hydrodesulfurization of a diesel fuel. The introduction of the modified zeolite into the composition of the ACM and ANM catalysts leads to increases in the fraction of volume occupied by pores with radii in the 10-150 nm range, from 29% (for the support) to 35-45%. The modified zeolite in the composition of the ANM hydrotreating catalyst affects the formation of the hydrogenated faces, in particular the surface nickel molybdates.
