Steam Gasification of Catalytic Pyrolysis Char for Hydrogen-rich Gas Production
Steam gasification of biochar from catalytic pyrolysis of biomass was studied in a fixed bed reactor at atmospheric pressure.The experiments were carried out at bed temperature of 700,750, 800 ℃ at steam flow rate of 0.1 g/min with reaction time of 3h.The gases produced included mainly H2, CO, CO2 and some small molecular hydrocarbons.The results showed that high gasification temperature was favorable for the production of hydrogen-rich gases.The maximum concentration of hydrogen exceeded 85% at 800 ℃ and the total gas yield increased with temperature rising.Meanwhile, the conversion efficiency of biochar at 700, 750, 800 ℃ was 48%,60%, 72% respectively.
