摘　　要：针对生活垃圾化学链式燃烧过程中可能出现的污染和腐蚀问题,研究了金属载氧体和HCl之间的相互作用.采用热力学平衡方法,分析了NiO、Fe2O3、CuO和CaSO4四种载氧体在不同温度下,水分和碳参与反应时氯气的生成情况;并进行了HCl和Fe2O3的高温反应实验.结果表明:温度对氯气的生成影响显著;水分的加入会减少氯气的生成;在有水分参与的反应中,碳的加入会使氯气生成量降低.从氯气生成量角度考虑,温度在700～900K时,Fe2O3可用作生活垃圾化学链式燃烧过程的载氧体.The interaction between oxygen carriers and chlorine hydride was investigated in this paper to evaluate the possibility of solid waste used as fuel in chemical looping combustion process.The effects of NiO,Fe2O3,CuO and CaSO4 on the production of chlorine,under different reaction conditions such as temperature,water and carbon content,were studied respectively using thermodynamic equilibrium approach.The experiment with Fe2O3 and chlorine hydride was investigated.The results showed that temperature had a significant influence on the production of chlorine;the addition of water would reduce the production of chlorine;the addition of carbon and water would inhibit the production of chlorine.In the view of chlorine production,Fe2O3 was suitable for the chemical looping combustion of solid waste at the temperature from 700 K to 900 K.
