Preparation method for novel gasoline hydrodesulfurization catalyst

The invention relates to a preparation method for a novel gasoline hydrodesulfurization catalyst. The preparation method for the novel gasoline hydrodesulfurization catalyst comprises the following steps of: uniformly mixing a solvent, a metal ion precursor and an organic ligand; and then carrying out aging and solvent heat crystallization on an obtained mixture; filtering, washing and drying a solvent heat crystallization product, so as to obtain ZIFs; treating the obtained ZIFs by acid to modify the ZIFs, so as to obtain a hydrodesulfurization catalyst carrier; loading an active component on the hydrodesulfurization catalyst carrier by using an equivalent-volume impregnation method; and drying and roasting the hydrodesulfurization catalyst carrier, so as to obtain the gasoline hydrodesulfurization catalyst. The catalyst obtained by using the preparation method provided by the invention obtains better reaction performance on the gasoline hydrodesulfurization aspect.
