The hydrolysate containing monosaccharide is fermented, degraded and liquefied to obtain a liquid fuel containing ethanol, gasoline and/or aromatic compound. The mixture containing bionic catalyst and cellulose biomass is hydrolyzed in thermodynamic field. The cellulose biomass is pretreated by strong acid or strong base high temperature and high pressure treatment, strong acid or strong base bursting method, ammonia bursting method and/or room temperature and atmospheric pressure chemical and physical field method. The physical field in room temperature and atmospheric pressure chemical and physical field method is ultrasound wave, microwave and/or magnetic force. The chemical reagent in room temperature and atmospheric pressure chemical and physical field method is substance which is recycled by distillation, preferably ammonia water or concentrated phosphoric acid. The mixture of cellulose biomass and concentrated phosphoric acid is disposed in physical field for treatment to obtain pretreated cellulose biomass. The pretreated cellulose biomass is separated to obtain cellulose, and phosphoric acid and organic solvent are recycled. The room temperature and atmospheric pressure chemical and physical field method of cellulose biomass is carried out by ultrasound wave field as physical field having frequency of 17 kHz-300 MHz, optimal frequency of 18 kHz-100 MHz, strength of 0.1 W-10 kW/L, preferably 0.1-30 W/cm3 and optimal strength of 2 W-6 kW, preferably 80-200 W/cm3, or ultrasound wave with 2 kW/20 kHz, microwave field as physical field with frequency of 300 MHz-300 GHz and strength of 0.1 W-10 kW/L, preferably 100-3000 W/L and/or magnetic force field as physical field with strength of 0.2-12 T.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The hydrolysate containing monosaccharide is extracted by an organic solvent or an exchange resin to obtain recycled catalyst. Preferred Compound: The exchange resin is macroporous adsorption resin, macroporous adsorption type weakly basic resin and/or heat regenerative resin.
