摘　　要：利用Fluent软件对生物质气化过程进行了模拟。首先研究了反应初始温度对反应装置最终温度的影响,结果显示初始温度在500~800 K内对最终温度的影响不是很明显;其次研究了用二氧化碳与空气、水蒸气混合物共同作气化剂时对最终气化产物的影响,结果表明气化剂中加入二氧化碳会提高一氧化碳和氢气的生成量,但是需要较高的反应温度。The biomass gasification process is simulated by fluent. First,the effect of the initial reaction temperature on the final temperature of the reactor is studied. Results show that the initial temperature has no obvoius effecting on the final temperature in the range of 500 ~ 800 K. Secondly,the effects of the gasifier in the mixture of carbon dioxide,air and water vapor on the final gasification products are studied. The results show that the addition of carbon dioxide to the gasifier may increase the amount of formation of the carbon monoxide and hydrogen,but a higher reaction temperature is required.
