    • 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.
    • 主要在400°F以上沸腾的重质含油量的加氢转化在蒸馏塔反应器中进行,同时将石油流进料到进料区; 氢在所述进料区下方的一点进料; 在催化蒸馏结构形式的裂化催化剂存在下蒸馏并接触石油物流,其总压力小于约300psig,氢分压为1.0至小于70psia,温度为 在400至1000°F的范围内,由此一部分石油流裂化成低于进料沸点沸点的较轻的产物,并将产物蒸馏以除去蒸气塔顶物流,其包含主要沸点低于 饲料和液体底部物流。
