The characteristics of biomass air-steam gasification in a fluidized bed for hydrogen-rich gasproduction are studied through a series of experiments. The gasifying agent, air, was suppliedinto the reactor from the lower part of the reactor, and steam was added into the reactor abovethe biomass feeding location. The effects of reactor temperature, steam-to-biomass ratio,equivalence ratio ER, and the biomass particle size on gas composition and hydrogen productionare investigated. From the experimental results, it can be seen that the higher reactortemperature, the proper ER, proper steam-to-biomass ratio S/B, and smaller biomass particlesize will contribute to more hydrogen production. The highest hydrogen yield, 71 g H₂/kg biomass(wet basis), was achieved at a reactor temperature of 900 C, ER of 0.22, and S/B of 2.70. It isshown that under proper operating parameters biomass air-steam gasification in a fluidizedbed is one effective way for hydrogen-rich gas production.
