DEEP CONVERSION PROCESS FOR RESIDUE MAXIMISING THE EFFICIENCY OF GASOLINE

摘要

the invention relates to a process for converting a deepheavy hydrocarbon includes the following steps: (a) a first stepto hydroconversion bubbling bed load, (b) a separation stepata portion of the liquid effluent hydroconverti from step (a), (c) (i)ahydrotreating step, at least a portion of the gas and thefractionvacuum gas oil from step (b), and (ii) a first stephydrocracking processat least a part of the gas oil fraction and the fraction of vacuum gas oilend ofthe step (b), (d) a step of splitting at least a portion of the effluent streamfromthe step (c) (i) and the step (c) (ii), (e) a step of recycling at least apart of thevacuum gas oil fraction is not converted from the fractionation step (d)inthe first step (a) hydroconversion, (f), a second stagehydrocracking processat least a portion of the gas resulting from step (d)fractionation; (g)a step of recycling part or all of the effluent from the point (f)the step(d) the splitting.
