摘要：
Steam gasification of biochar from fast pyrolysis of biomass was conducted in a fixed bed reactor. The experiments were carried out at temperature of 700, 750, 800 degrees C with steam flow rate of 0.1 g/min and reaction time of 3 h. The gas products mainly included H-2, CO, CO2 and some hydrocarbons with low carbon number. The results showed that the conversion of biochar at 700, 750, 800 degrees C was 68, 78, 96 wt%, respectively, and high gasification temperature favored the production of hydrogen-rich gases. The hydrogen yield increased with temperature rising and reached the maximum of 35.70 mol/kg with a hydrogen concentration of 74 V% at 800 degrees C.
