Patent ID: 8691080

Claim:
A slurry hydrocracking process, comprising: A) combining one or more hydrocarbons and a slurry hydrocracking catalyst comprising a support as a feed to a slurry hydrocracking reaction zone; B) fractionating an effluent from the slurry hydrocracking reaction zone to provide a light vacuum gas oil, a heavy vacuum gas oil, and a mixture comprising a pitch and the slurry hydrocracking catalyst; C) separating the pitch from at least a portion of the slurry hydrocracking catalyst to obtain a filtrate comprising the pitch and a retentate comprising the slurry hydrocracking catalyst; D) backwashing the retentate with at least a part of the heavy vacuum gas oil wherein the separated slurry hydrocracking catalyst is comprised in a suspension; and E) recycling the suspension to the slurry hydrocracking reaction zone.
