Abstract
Slurry hydrocracking processes are described. The methods include hydrotreating a heavy residual hydrocarbon feed in a hydrotreating zone under residual hydrotreating conditions to form a hydrotreated effluent. The hydrotreated effluent is separated in an first separator to form an overhead vapor stream and a bottoms stream. The bottoms stream is hydrocracked in a slurry hydrocracking zone under slurry hydrocracking conditions. The effluent from the slurry hydrocracking zone is fractionated in a fractionation zone into at least two streams. Slurry hydrocracking apparatus is also described.
