摘要：
Phosphorus and fluorine additives incorporated into the Ni-Mo/Al2O3 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 catalysts is proved by XPS and P-31 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.
