1. the method for a selectively hydrogenating and desulfurizing inferior gasoline, comprise the hydrogenating desulfurization processing of bad gasoline and separating of hydrogenating desulfurization product, wherein separate the hydrogen-rich gas obtain as recycle hydrogen, the hydrodesulfurization process that it is characterized in that described bad gasoline is as follows:

  • bad gasoline, depriving hydrogen sulphide agent and hydrogen are contacted with catalyst for selectively hydrodesulfurizing, under the hydrodesulfurization reaction condition, carry out the selective hydrodesulfurization reaction, described depriving hydrogen sulphide agent is basic solvent, H in the described recycle hydrogen 2S concentration is controlled at 20 μ

    g/g~

    500 μ

    g/g;

    Described catalyst for selectively hydrodesulfurizing is to adopt a kind of highly active Hydrobon catalyst and a kind of SA Hydrobon catalyst, its volume percent is 20/80~

    80/20, and wherein highly active Hydrobon catalyst is positioned at the upstream of SA Hydrobon catalyst;

    Metal oxide content is 8.0wt%~

    20.0wt% in the described high activity hydrogenation and desulphurization catalyst, and auxiliary agent content is 1.0wt%~

    6.0wt%;

    Metal oxide content is 1.0wt%~

    12.0wt% in the SA Hydrobon catalyst, and auxiliary agent content is 1.0wt%~

    6.0wt%.
