Process for the preparation of light hydrocarbon distillates by hydrocracking and catalytic cracking.

摘要

Process for the preparation of a light hydrocarbon oil distillate by (1) hydrocracking a heavy vacuum distillate, (2) separating the product of (1) into distillates and a residue, (3) catalytic cracking the residue obtained in (2) and (4) isolating a light hydrocarbon oil distillate from the product of (3), in which process the residue obtained in (2) is catalytically cracked in (3) together with a further quantity of said heavy vacuum distllate.
