In this paper, the catalytic functions of molybdenum, nickel, and iron were studied respectively during the slurry-phase hydrocracking while using diphenylmethane as the model compound and AR from Karamay crude as the feedstock. The test results showed that, during the slurry-phase hydrocracking of heavy oil, the metal sulfides entered into chemical reactions with the free-radical intermediate H ; formed on the catalyst surface. The free-radical intermediate H ; formed on the catalyst surface could react with the free radicals of large molecules and could suppress coke deposition.
