PROCESS FOR THE PRODUCTION OF MIDDLE DISTILLATE FROM A CONVENTIONAL HEAVY FEEDSTOCK INCLUDING A STEP FOR SELECTIVE HYDROGENATION OF THE EX FCC HCO CUT

摘要

The present invention describes a process for the conversion of a heavy feedstock for improving the production and selectivity for middle distillate, said process using a catalytic cracking unit followed by a unit for selective hydrogenation of the heavy distillate cut (HCO) or any other cut rich in triaromatic compounds before recycling it to the FCC reaction zone in order to maximize the middle distillate cut.
