Patent ID: 7799208

Claim:
A method of hydrocracking a hydrocarbonaceous stream comprising: providing a hydrocarbonaceous feed stock having a boiling point range; directing the hydrocarbonaceous feed stock to a hydrotreating zone to produce a hydrotreating zone effluent; directing the hydrotreating zone effluent to a separation zone to separate one or more lower boiling point hydrocarbon streams from a higher boiling point liquid hydrocarbon stream; taking at least a portion of the higher boiling point liquid hydrocarbon stream as a hydroprocessing feed; admixing an amount of hydrogen with the hydroprocessing feed such that substantially liquid-phase conditions are maintained; directing the hydroprocessing feed to a substantially liquid-phase continuous hydrocracking zone; and reacting the hydroprocessing feed substantially undiluted with another hydrocarbon stream in the substantially liquid-phase continuous hydrocracking zone with a hydrocracking catalyst under hydrocracking conditions to produce a hydrocracking zone effluent having hydrocarbons with a lower boiling point range relative to the higher boiling point liquid hydrocarbon stream.
