Abstract:
1. A process for the conversion of a hydrocarbonaceous feedstock wherein the process comprises: (a) reacting a hydrocarbonaceous feedstock comprising light cycle oil and vacuum gas oil in a hydrodesulfurization reaction zone to produce a hydrocarbonaceous stream having a reduced concentration of sulfur; (b) introducing at least a portion of the hydrocarbonaceous stream having a reduced concentration of sulfur into a separation zone to produce a vaporous hydrocarbonaceous stream and a liquid hydrocarbonaceous stream having a reduced concentration of sulfur and boiling in a range greater than the vaporous hydrocarbonaceous stream; (c) introducing at least a portion of the vaporous hydrocarbonaceous stream into a hydrocracking reaction zone containing hydrocracking catalyst to produce an effluent stream comprising naphtha boiling range hydrocarbons; (d) the hydrocracked effluent stream introduced into a fractionation zone, and the liquid hydrocarbonaceous stream introduced to the fractionation zone bypassing the hydrocracking zone; (e) recovering naphtha boiling range hydrocarbons; and (f) recovering a hydrocarbonaceous stream as an FCC feedstock.
