Abstract
A method for processing an inferior gasoline and a system for processing the same. In the method, a full range gasoline is subjected to a directional sulfur transfer reaction, then is cut to obtain a light gasoline fraction, a medium gasoline fraction and a heavy gasoline fraction; the light gasoline fraction is treated to obtain an alkylated light gasoline; the medium gasoline fraction is treated to obtain a raffinate oil and an extracted oil; the raffinate oil is treated to obtain an esterified medium gasoline; the heavy gasoline fraction is mixed with the extracted oil to obtain a mixed oil, and an one-stage hydrodesulfurization reaction, a two-stage hydrodesulfurization reaction, HS-removal and a hydrocarbon isomerization/aromatization reaction are carried out successively to obtain a treated heavy gasoline; blending the alkylated light gasoline, the esterified medium gasoline and the treated heavy gasoline to obtain a clean gasoline.
