Patent ID: 7368619

Claim:
A process for the production of low sulfur diesel and aromatic compounds which process comprises: (a) reacting a hydrocarbonaceous stream comprising C 9 + hydrocarbons in a hydrocracking zone containing a hydrocracking catalyst to produce a hydrocracking zone effluent comprising xylenes; (b) passing the hydrocracking zone effluent into a hot high pressure stripper to produce an overhead vapor stream comprising hydrocarbons boiling in the range from about 38° C. (100° F.) to about 220° C. (428° F.) and a liquid hydrocarbon stream comprising hydrocarbons boiling above about 220° C. (428° F.); (c) condensing at least a portion of the overhead vapor stream comprising hydrocarbons boiling in the range from about 38° C. (100° F.) to about 220° C. (428° F.) to produce a liquid hydrocarbon stream comprising hydrocarbons boiling in the range from about 38° C. (100° F.) to about 220° C. (428° F.); (d) separating and reacting at least a portion of the liquid hydrocarbon stream produced in step (c) and make-up hydrogen in a transalkylation zone to produce a liquid hydrocarbonaceous transalkylation effluent and a gaseous stream comprising hydrogen; (e) passing at least a portion of the gaseous stream comprising hydrogen produced in step (d) to the hydrocracking zone, and (f) recovering xylenes.
