摘　　要：在自制的固定床反应器中,采用核桃壳、花生壳、锯末3种原料,以三氧化二铝、二氧化锰、氧化钙为催化剂,进行了催化热解制备氢气的试验研究。结果表明,随着热解温度升高,热解气体中氢气含量相应升高,当温度超过600℃以后氢气含量则显著升高。热解温度每升高100℃,氢气体积分数约增加10%左右。进一步的结果表明,不同类型的催化剂在不同用量下,具有不同的催化效果。Experiment of catalytic pyrolysis to prepare hydrogen was carried out in a self-made fixed-bed reactor, using chestnut shell, peanut shell and sawdust as raw materials and A1203 , MnO2 , CaO as catalysts. Results showed that content of hydreogen in pyrolysis gas increased with increase of pyrolysis temperature, and increased markedly over 600 ℃. Volumetric fraetion of hydrogen was increased about 10 % per 100 ℃ increment of pyrolysis temperature. Further results showed that catalyst of different types under different dosages possessed different catalytic effects.
