Patent ID: 8617384

Claim:
A process for maximizing p-xylene production comprising the steps of: producing a naphtha fraction and a light cycle oil fraction from a fluid catalytic cracking zone; combining the naphtha and the light cycle oil fractions; hydrotreating the combined naphtha and light cycle oil fractions to produce a hydrotreated product; fractionating the hydrotreated product in a fractionation zone to make a light ends cut, a naphtha cut, a hydrocracker feed and an unconverted oil fraction; sending the hydrocracker feed to a hydrocracking zone to make a hydrocracker product; recycling the hydrocracker product to the fractionation zone, feeding the hydrocracker product above an outlet for the hydrocracker feed, but below an outlet for the naphtha cut; sending the naphtha cut to a dehydrogenation zone to make a dehydrogenated naphtha; and feeding the dehydrogenated naphtha to an aromatics recovery unit to recover p-xylene and other aromatics.
