SLURRY HYDROCONVERSION WITH HIGH ACTIVITY CATALYSTS

摘要

Systems and methods are provided for slurry hydroconversion of a heavy oil feed, such as an atmospheric or vacuum resid. The systems and methods allow for slurry hydroconversion using catalysts with enhanced activity. The catalysts with enhanced activity can be used in conjunction with demetallization catalysts or catalysts that can be recycled as a side product from a complementary refinery process.

1. A method for processing a heavy oil feedstock, comprising:
providing a heavy oil feedstock having a 10% distillation point of at least about 650° F. (343° C.) and a first Conradson carbon residue wt %; exposing the heavy oil feedstock to a slurry hydroconversion catalyst in one or more reactors under effective slurry hydroconversion conditions to form a slurry hydroconversion effluent, the effective slurry hydroconversion conditions being effective for conversion of at least about 80 wt % of the second heavy oil feedstock relative to a conversion temperature of 1050° F. (566° C.), such as at least about 90 wt %; separating a bottoms product from the slurry hydroconversion effluent, the bottoms product having a 10% distillation point of at least about 650° F. (343° C.); and hydrocracking at least a portion of the bottoms product in the presence of a hydrocracking catalyst under effective hydrocracking conditions, the at least a portion of the bottoms product having a final boiling point of at least about 1050° F. (566° C.),
wherein the slurry hydroconversion catalyst comprises a bulk multimetallic catalyst comprising at least one non-noble Group VIII (Group 8-10) metal and at least one Group VIB (Group 6) metal, a weight of the slurry hydroconversion catalyst being about 2 wt % to 25 wt % of a weight of the heavy oil feedstock in the reactor.
