Patent ID: 7265252

Claim:
A process for the production of xylene comprising (a) reacting a first hydrocarbonaceous stream comprising C 9 + hydrocarbons in a hydrocracking zone over a hydrocracking catalyst to produce a hydrocracking zone effluent comprising xylenes; (b) reacting at least a portion of the hydrocracking zone effluent in a transalkylation zone over a transalkylation catalyst to produce a transalkylation zone effluent; (c) passing the transalkylation zone effluent into a product separator to produce a product stream and a second hydrocarbonaceous stream comprising C 9 + hydrocarbons; (d) passing at least a portion of the second hydrocarbonaceous stream comprising C 9 + hydrocarbons to the hydrocracking zone; and (e) recovering xylenes from the product stream produced in step (c).
