Abstract
A catalytic conversion process for producing gasoline and propylene includes the steps of 1) subjecting a feedstock oil to a first catalytic conversion reaction in a first catalytic conversion reaction device to obtain a first reaction product; 2) separating the first reaction product to obtain a propylene fraction, a gasoline fraction and a fraction comprising Colefin; 3) carrying out an oligomerization reaction on the fraction comprising Colefin in an oligomerization reactor to obtain an oligomerization product comprising Colefin, and optionally separating the oligomerization product to obtain a fraction comprising Colefin; 4) recycling the Colefin-containing oligomerization product or fraction to the first catalytic conversion reaction device, and/or sending the Colefin-containing oligomerization product or fraction to a second catalytic conversion reaction device for a second catalytic conversion reaction to obtain a second reaction product comprising propylene.
