Embodiment Construction
[0030] The present invention is further described below in conjunction with embodiment, but does not constitute limitation to the present invention.
[0031] Select agricultural and forestry processing waste as biomass raw material, with an average particle size of 0.8mm; Fe 2 o 3 The ferric oxide particles with a mass percentage content of 60% are oxygen carriers, and the average particle diameter is 0.5 mm; the inner diameter of the bubbling fluidized bed 2 is 300 mm, and the height is 1200 mm; the diameter of the fluidized bed riser 4 is 100 mm, and the height is 2000 mm. The amount of oxygen carrier particles added is 30-40kg, and fresh oxygen carriers can be added to the bubbling fluidized bed 2 at any time according to the reaction process. The temperature of the bubbling fluidized bed 2 is stabilized within the range of 840-850°C, the temperature of the fluidized bed riser 4 is controlled within 900-950°C, and the synthesized gas is discharged and purified from the exh...
