摘　　要：在实验室自制固定床热解反应器中，选择生物质花生壳作为实验材料，研究并比较了过渡金属氧化物和非过渡金属氧化物作为催化剂时催化热解制备富氢可燃气的催化效果。结果表明：花生壳热解产气过程中，氢气产率与可燃气产量随热解温度变化的基本趋势不因催化剂或催化剂添加剂量的改变而改变；2％的MnO2（占入料质量的百分比）最有利于花生壳热解产氢；适量催化剂在花生壳催化热解制备富氢可燃气有效作用温度区间是500°-800℃。The agricultural waste, peanut shell, is selected for pyrolysis in a laboratory fixed bed reactor to prepare fuel gases with high H2 at different temperatures with catalysts（MnO2. TiO2. Al2O3. CaO）. The results indicate： The addition of catalysts could not change the general principle of gas yield of the peanut shell pyrolysis increases with the rise of the temperature; MnO2 precedes other catalysts to produce hydrogen from pyrolyzing peanut shell; The effect of catalytic temperature on pyrolysis peanut shell to produce combustible gas is studied as well, and of some the catalysts work a bit better efficiently at the temperature around 500-800℃.
