Abstract

Abstract:

Using oxygen and steam was mixed gasification agent, experiments were conducted on oxygen and steam gasification of bamboo chips in a fixed-bed gasification reactor. The effects of gasification temperature, steam flow rate, and O₂ equivalence ratio on gasification of bamboo sawdust for production of hydrogen-rich gas were investigated. The research results showed that both gasification temperature and steam flow rate had a significant impact on the volumetric fraction of H₂ in bamboo sawdust gas. The volumetric fraction of H₂ showed a steady growth trend with the increase of gasification temperature, and first increased and then decreased with the increase of steam flow rate.The maximum value of H₂ volume fraction was achieved at gasification temperature of 900 ℃ and steam flow rate of 0.7 mL/min, respectively. As the O₂ equivalence ratio increased, the volumetric fraction of H₂ did not changed significantly. The optimal oxygen and steam gasification conditions for preparing hydrogen-rich gas by oxygen-steam gasification from bamboo chips were gasification temperature of 900 ℃, steam flow rate of 0.7 mL/min, and O₂ equivalence ratio of 0.30. Under this condition, the volumetric fraction of H₂ in the gas produced by gasification was 32.04%, the calorific value was 11.37 MJ/m³, the gas production rate was 1.40 L/g, the volumetric fraction of CH₄ in the gas was 8.82%, the volumetric fraction of CO was 26.34%, the volumetric fraction of CO₂ was 30.55%, and the volumetric fraction of C₂H_m was 2.24%.
