Phosphorus and flourine additives incorporated into the Ni-Mo/Al{sub 2}O{sub 3} sulfided catalysts on various stages of their preparation considerably lower the activation energy of the thiophene hydrogenolysis reaction. The interaction of promoting additives with the active component of the hydrodesulfurization catalyst is proved by XPS and {sup 31}P NMR. The effect of additives is discussed in terms of a synchronous mechanism involving interaction of reacting molecules in the coordination sphere of a bimetallic sulfide compound.
