摘要： The present invention relates to a catalytic conversion process for producing more diesel and propylene, comprising contacting the feedstock oil with a catalyst having a relatively homogeneous activity in a reactor, wherein the reaction temperature, weight hourly space velocity and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from 12 to 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil; the fluid catalytic cracking gas oil is fed into the fluid catalytic cracking gas oil treatment device for further processing. Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstocks for catalysis are selectively cracked and isomerized. Meanwhile, aromatics in the feedstocks, which enter into the diesel fraction, are minimized, and the retention of other components in the diesel fraction by the production of aromatics via the reaction such as aromatization and the like is avoided. While the feedstocks are converted into high cetane number diesel and propylene, the yields of dry gas and coke are significantly reduced, and the breaking tendency and consumption of the catalyst are decreased.
