In a crude oil refining apparatus, heavy cycle oil from the catalytic cracking unit employed in the crude oil refining apparatus is recycled to a hydrofining process. Such recycling improves the value of the product mix obtained from the crude oil refining apparatus with respect to an apparatus in which the heavy cycle oil withdrawn from the catalytic cracking units is recycled to the catalytic cracking units.
