摘　　要：本文考察了Co/HZSM-5和Co-Ca/HZSM-5两种改性分子筛对稻壳热解产气的影响规律。结果表明,Co-Ca/HZSM-5能够显著提高可燃气产率,相较于单金属Co改性,气体产率提高了25%,H_(2)体积分数提升了66.70%;双金属改性分子筛的催化活性要优于单金属改性分子筛。The effects of two modified catalyst including Co/HZSM-5 and Co-Ca/HZSM-5 on the pyrolysis of rice husk were investigated.The results show that Co-Ca/HZSM-5 can significantly improve the gas production rate.Compared with single cobalt metal modification,the syngas yield was increased by 25% and the H_(2)content is increased by 66.70%.The catalytic activity of bimetallic modified zeolite is better than that of mono-metal modified zeolite.
