Abstract: An integrated thermal and catalytic process for improving the yield of middle distillate from heavy petroleum oil feeds comprises cracking the heavy portion (345° C.+) of the feed in a thermal conversion zone, followed by hydrotreating the thermally cracked product and the lighter portion of the feed and then separating the hydrotreated product into a bottoms fraction which is passed to a catalytic cracking step.
