Hydrocarbon conversion process

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 hot, high pressure stripper 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 hydrocarbonaceous stream as an FCC feedstock.

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 operated at a temperature from about 204° C. (400° F.) to about 482° C. (900° F.), a pressure from about 3.5 MPa (500 psig) to about 17.3 MPa (2500 psig) and a liquid hourly space velocity from about 0.1 hr−1 to about 10 hr−1 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 hot, high pressure stripper operated at a temperature from about 149° C. (300° F.) to about 399° C. (750° F.) and a pressure from about 3.5 MPa (500 psig) to about 17.3 MPa (2500 psig) 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 and operated at a temperature from about 232° C. (450° F.) to about 468° C. (875° F.) and a pressure from about 3.5 MPa (500 psig) to about 17.3 MPa (2500 psig) 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 from the fractionation zone as an FCC feedstock.
