ABSTRACT:
The hydroconversion of heavy petroliferous stocks boiling mainly above 400.degree. F. is carried out in a distillation column reactor where concurrently a petroleum stream is fed into a feed zone; hydrogen is fed at a point below said feed zone; the petroleum stream is distilled and contacted in the presence of a cracking catalyst prepared in the form of a catalytic distillation structure at total pressure of less than about 300 psig and a hydrogen partial pressure in the range of 1.0 to less than 70 psia and a temperature in the range of 400 to 1000.degree. F. whereby a portion of the petroleum stream is cracked to lighter products boiling below the boiling point of the feed and products are distilled to remove a vaporous overhead stream comprising products mainly boiling below the boiling point of the feed and a liquid bottoms stream.
