摘要/Abstract

摘要： 以木屑为生物质原料，水蒸气为气化介质，CaO为催化剂，在固定床气化炉中进行生物质催化气化制取富氢燃气，考察了CaO与木屑中碳元素的物质的量比（n（Ca）/n（C））、气化温度和水蒸气流量对生物质水蒸气气化特性的影响。结果表明，当n（Ca）/n（C）由0增加至1.0时，H₂体积分数由45.58%增至58.62%，产气率由1.04 m³/kg增至1.38 m³/kg，当n（Ca）/n（C）继续增至1.5时，两者均有增加，但是变化不明显；气化温度从700 ℃增至750 ℃时，产气中H₂体积分数由51.78%增至58.62%，CO₂由19.89%降至12.60%，继续升高温度，H₂体积分数逐渐降低，燃气热值也降低；水蒸气流量由0.1 g/（min·g）增至0.34 g/（min·g）时，H₂的体积分数由58.62%增至62.55%，水蒸气流量继续增大时，H₂的体积分数和产氢率降低，燃气热值也降低。通过实验选择的最佳气化条件为以CaO为催化剂，n（Ca）/n（C）为1，气化温度750 ℃，水蒸气流量为0.34 g/（min·g），此时，制取的富氢燃气中H₂体积分数达到最大为62.55%，产氢率为85.08 g/kg，燃气热值为11.41 MJ/m³。

Abstract: The steam gasification experiments of sawdust for production of hydrogen-rich gas were carried out in the high-temperature fixed bed reactor using steam as gasification agent and CaO as catalyst. The effects of the molar ratio of CaO and carbon element of sawdust (n(Ca)/n(C)), temperature and steam flow rate on gasification characteristics were investigated. The results showed that with the increament of n(Ca)/n(C) from 0 to 1.0, the volume fraction of hydrogen increased from 45.58% to 58.62%, and the dry gas yield increased from 1.04 m³/kg to 1.38 m³/kg; the hydrogen content and dry gas yield only showed a modest increase as the n(Ca)/n(C) increased to 1.5. With increasing the gasification temperature from 700 to 750 ℃, the volume fraction of hydrogen significantly increased from 51.78% to 58.62%, and that of carbon dioxide decreased from 19.89% to 12.60%; as the temperature kept rising, the hydrogen content and the low heating value decreased. By increasing the steam flow rate from 0.1 g/(min·g) to 0.34 g/(min·g), the volume fraction of hydrogen increased from 58.62% to 62.55%. However, the hydrogen content, the hydrogen yield and the low heating value decreased when the steam flow rate was higher than 0.34 g/(min·g). The optimized conditions with CaO as catalyst were n(Ca)/n(C)=1, the gasification temperature 750 ℃ and the steam flow rate 0.34 g/(min·g). Under these conditions, the volume fraction of hydrogen was 62.55%, the hydrogen yield was 85.08 g/kg, the low heating value was 11.41 MJ/m³.
