Preparation method and application of reduced copper/nickel-based adsorption catalyst

The invention discloses a preparation method and application of a reduced copper/nickel-based adsorption catalyst. The method comprises the following steps: 1, mixing copper-containing metal salt powder and nickel-containing metal salt powder, and pyrolyzing to obtain copper/nickel oxide mixed powder; 2, mixing the copper/nickel oxide mixed powder with carbon powder, alumina powder, clay and a binder, and extruding into strips; 3, roasting the strip-shaped object in flowing nitrogen mixed with water vapor; 4, cooling to normal temperature under nitrogen protection to obtain a catalyst; the catalyst is applied to a liquid hydrocarbon raw material purification process. According to the invention, the carbon powder is added into the preparation raw materials, and a small amount of water vapor is added during roasting, so that copper oxide and nickel oxide are fully reduced, the catalyst with high reduction degree is obtained, the reaction activation energy of the catalyst is reduced, and the desulfurization perf
