Abstract
A catalytic cracking gasoline upgrading method is provided. First, in the presence of a prehydrogenation catalyst, the full-range FCC gasoline undergoes prehydrogenation in a prehydrogenation reactor to remove diolefins, mercaptans and sulfides, and then the prehydrogenation product undergoes selective hydrodesulfurization in the presence of a hydrodesulfurization-isomerization catalyst, and straight-chain olefins are isomerized into single-branched olefins or single-branched alkanes, thus obtaining a low-olefin, ultralow-sulfur and high-octane clean gasoline product.
