Problems solved by technology
The invention discloses a residual oil hydrodemetallization method. According to the method, raw materials comprise a residual oil raw material, hydrogen and a material viscosity adjusting auxiliary agent, wherein the material viscosity adjusting auxiliary agent comprises ethylene tar, and the fed materials are subjected to a hydrotreatment reaction in a hydrodemetallization reaction zone to obtain a hydrogenation effluent; and the hydrodemetallization reaction zone is filled with at least one hydrodemetallization catalyst and at least one hydrogenation protective agent. According to the method disclosed by the invention, the ethylene tar is added into the residual oil raw material as a material viscosity adjusting aid, so that the system viscosity under the reaction condition can be effectively reduced, the hydrodemetallization of the residual oil is promoted, and the improvement of the reaction performances such as subsequent desulfurization, and carbon residue removal and the like is facilitated through the synergistic effect of all the components under the hydrodemetallization reaction condition.
