Patent ID: 7815793

Claim:
A process for reducing the Bromine Index of a hydrocarbon feedstock having at least 40 wt. % of C 8 aromatics and less than 0.5 wt % toluene, and having a Bromine Index of at least 100, comprising the step of contacting said hydrocarbon feedstock with a catalyst at conversion conditions, wherein said catalyst includes clay and a spent molecular sieve having a zeolite structure type of MWW to produce a product and passing said product to a step of distillation and then recovering a distilled product from said distillation, said distilled product comprising xylenes and characterized by having a Bromine Index at least 50% less than the Bromine Index of said hydrocarbon feedstock and a concentration of benzene less than 1000 wppm higher than the concentration of benzene in said feedstock, said process further characterized in that the amount of benzene present in said distilled product decreases over time.
