The catalytic activity in the hydrodesulfurization reaction of type A, L, X, Y zeolites and mordenite, modified with cobalt and nickel and impregnated with molybdenum salts in the ratio Co (Ni) : Mo = 0.2-2.5, was studied by the pulse microcatalytic method. It was established that Ni-Mo and Co-Mo zeolites of type X and Y achieve conversion of thiophene to a mixture of butenes and butanes. Addition of Co-Mo zeolites of type X and Y (Co : Mo = 1.8-2.5) to commercial samples of Al-Co-Mo (ACM) and Al-Ni-Mo (ANM) decreases the activity of ACM in hydrodesulfurization of thiophene, while introduction of the zeolite 0.9 NiX/MoO/sub 3/ (Ni : Mo = 2.2) increases the activity of ANM by two times. Type A, L zeolites and mordenite having a high content of active metals are catalytically inactive.
