Abstract
One exemplary embodiment can include a slurry hydrocracking process. The process can include combining one or more hydrocarbons and a slurry hydrocracking catalyst as a feed to a slurry hydrocracking reaction zone, fractionating an effluent from the slurry hydrocracking reaction zone, separating the pitch from at least a portion of the slurry hydrocracking catalyst, and recycling the suspension to the slurry hydrocracking reaction zone. The slurry hydrocracking catalyst may include a support. Fractionating the effluent may provide a light vacuum gas oil, a heavy vacuum gas oil, and a mixture comprising a pitch and the slurry hydrocracking catalyst. Generally, the separated slurry hydrocracking catalyst is comprised in a suspension.
Claims4
A slurry hydrocracking apparatus, comprising:
- A) a slurry hydrocracking reaction zone providing an effluent comprising one or more hydrocarbons and a slurry hydrocracking catalyst;
- B) a vacuum fractionation zone receiving the effluent and providing a mixture comprising the slurry hydrocracking catalyst;
- C) a filtration zone adapted to filter the mixture to provide a retentate comprising the slurry hydrocracking catalyst and a filtrate comprising a pitch;
- and
- D) a line communicating the retentate from the filtration zone for recycling the retentate to the slurry hydrocracking reaction zone.
