Abstract
The hydrofining process and the catalyst have stronger hydrodesulfurization capability (75-95% HDS) than the traditional hydrofining catalyst, and the desulfurized gasoline has smaller octane number loss (the RON is reduced by 3-4 units). The catalyst does not contain any harmful substance, and has excellent catalytic activity and good stability. The method adopts a catalyst and a gas phase hydrogenation process, wherein the reaction pressure of the process is 1-4 MPa, the reaction temperature is 240-350 ℃, and the liquid phase space velocity LHSV is 1-10 h-1The volume ratio of hydrogen to oil is 100-500.
