Integrated membrane/hydrocracking process for improved feedstock utilization in the production of reduced emissions gasoline

Abstract From the Canadian patent

A method for improving and maximizing the utilization of hydrocarbon feedstock in the production of reduced emissions gasoline is disclosed comprising fractionating cat cracker effluent into a reduced emissions gasoline blending stream a heavy cat naphtha stream, and a light cat cycle oil feeding the heavy cat naphtha and, optionally a part of the light cat cycle oil to a selective membrane extraction unit wherein a saturates rich retentate and an aromatics polar, and heteroatom rich permeate are produced hydrotreating the retentate, to produce high quality jet fuel or distillate and hydrocracking the aromatics rich permeate to produce hydrocrackate and gas.
