Abstract: Disclosed is a method for preparing cellulose and lignin oil by depolymerizing lignocellulose without exogenous hydrogen, including: performing reaction on the lignocellulose dispersed into an aqueous medium at 120° C. to 180° C. under the action of a catalyst; and separating a reaction product to obtain the cellulose and the lignin oil. The catalyst includes a carrier and an active ingredient loaded on the carrier, where the active ingredient is selected from one of platinum, palladium, ruthenium and nickel; the carrier is selected from one of a metal oxide, a metal composite material, silicon dioxide, nitrogen-doped carbon, molybdenum carbide and molybdenum nitride; and the metal oxide is selected from one of niobium oxide, tantalum oxide, tungsten oxide, zirconium oxide, aluminum oxide, titanium dioxide and molybdenum oxide.
