Abstract The present invention is one technological process of multistage hydrogenating and cracking inferior heavy and residual oil in suspension bed. Ropy crude oil or atmospheric and vacuum residual oil obtained through distillation are mixed with hydrogenating catalyst homogeneously and the mixture takes cracking hydrogenation reaction inside one hydrogenation cracking reactor and produces low boiling point product in the presence of high pressure hydrogen (6-18 MPa). The multistage hydrogenating apparatus for the suspension bed hydrogenation includes at least one section of high temperature reaction region and one section of low temperature reaction region.
