Abstract In the heavy oil and residual oil hydrogenating conversion process, reaction material is first hydrogenated and converted at low temperature for long period inside one suspended bed or similar reactor, and then hydrogenated and converted at high temperature for short period inside one other suspended bed or similar reactor. Through the hydrogenation pre-treatment in the first section suspended bed, the residual oil has raised H/C ratio and asphalt well dispersed in the colloid suspension liquid, so that the hydrogenation conversion in the high temperature suspended bed of the residual oil has high residual oil converting rate and low coke producing rate, and the equipment has long operation life and suitable ofr industrial application.
