Abstract: 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.
