摘　　要：通过对HCl氧化制Cl2的Deacon过程的热力学和动力学分析以及实验研究,得到了HCl催化氧化制Cl2过程的优化工艺条件,即进料HCl/O2摩尔比为4、HCl质量空速为0.45h-1、反应温度为450℃、常压,在此条件下HCl和O2的转化率均为65%,产物中Cl2干基含量为78.8%,O2干基含量为21.2%.In the production process of chlorine from HCl by catalytic oxidation, in order to decrease the energy consumption for separating HCl and O2 and increase the yield of chlorine, the conversion rates of both HCl and O2 must be high enough. According to thermodynamic and kinetic analysis and experiments, the optimal reaction conditions for the process are obtained, which are temperature 450℃, pressure 0.11 MPa, molar ratio of HCl to O2 4, and WHSV of HCl 0.45 h^-1. Under the reaction conditions, the conversion rates of both HCl and O2 are 65%, and the dry contents of Cl2 and O2 78.8% and 21.2%, respectively.
