Abstract
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 feedstock for catalysis are selectively cracked and isomerized.
