Desalted crude oil plus a recycle stream from a catalytic cracking unit, e.g., catalytic gas oil (heavy catalytic cycle oil), with or without other cat cracking products, e.g., gasoline and light cycle oil, are mixed and hydrotreated together in a single operation; then fractionated into the desired fractions. Optionally, portions of the products from said hydrotreater can be reformed and/or coked with liquid fractions from said coker optionally being recycled to join the crude oil feed to the hydrotreater.
