[0038] Example: Using 0.2 mol / L glucose as a biomass model compound, a biomass supercritical water gasification hydrogen production experiment was carried out in the absorption reactor. Experimental location: Xi'an, 108°55' east longitude, 34°15' north latitude, the average direct solar radiation intensity of the day was 720w / m 2 The tube length of the serpentine tube flow reactor is 30m, and the length ratio of the preheating section and the reaction section is 0.6; the mass flow rates of the preheated water and the biomass raw material slurry are 3.6kg / h and 1.2kg / h respectively; the fluid pressure in the reactor is 24MPa; the diameter of the daylight opening of the solar absorber cavity is 250mm; the inclination angle of the solar absorber is 19.4°. Under the above conditions, the reactor achieves continuous and high-efficiency hydrogen production, the gasification rate of glucose exceeds 110%, the highest carbon gasification rate exceeds 77%, and the volume concentration o...
