FIELD: chemistry.
SUBSTANCE: method includes feeding a hydrocarbon stream containing one or more C40+ hydrocarbons into a thermal conversion zone to obtain a hydrocarbon distillate fraction stream and a gas oil stream; feeding the gas oil stream into a gas oil hydrofining zone to obtain hydrofined gas oil; feeding said hydrofined gas oil into a fluidised-bed catalytic cracking zone to obtain light recycle gas oil; feeding the light recycle gas oil into a hydrocracking zone to perform selective hydrocracking of aromatic compounds containing at least two rings to obtain a processed distillate product and recycling at least part of the processed distillate product from the selective hydrocracking zone into the fluidised-bed catalytic cracking zone.
EFFECT: method increases efficiency of the selective hydrocracking zone and enables to obtain a distillate product of high quality from crude oil.
