【摘要】 以木屑和稻壳为试验原料,针对生物质气化热解技术开展研究。实验结果表明,CO、H₂、CH₄等是组成合成气的主要有效成分;反应终温对气化热解反应的结果影响较大。当反应终温从700℃上升至900℃时,合成气产率提升了39. 6%;原料含水率对合成气的组分构成也有影响,含水率越高,H₂占比越小,同时无效热值气体CO₂含量占比上升。更多还原

【Abstract】 Sawdust and rice husk were used as experimental materials to study biomass gasification and pyrolysis characters. The experimental results show that CO,H₂,CH₄ are the main effective components of syngas. And the final temperature has a great influence on the results of gasification and pyrolysis. When the final temperature of the reaction rises from 700 ℃ to 900 ℃,the yield of syngas increases by 39. 6%;the moisture content of raw material also affects the composition of syngas. The higher the moisture content,the smaller the proportion of H₂,and the higher the proportion of CO₂ in the invalid calorific value gas.更多还原
