摘要：The chlorine from HCl can be recycled by catalytic oxidation during the industrial process, but excessive heat will be produced during the HCl catalytic oxidation, which leads to catalyst deactivation. Thus, a study of the reaction kinetics of HCl catalytic oxidation over a Cu-based composite catalyst is necessary. The influence of T values of 360-400 degrees C, n(HCl)/n(O2), values of 1-4, and F-HC10/W values of 0.01-60 h(-1) on HCl conversion and reaction rate was studied, and a kinetic model was established by a MATLAB parameter fit and a statistical test. Results show that, before chemical equilibrium, HCI conversion and reaction rate increase with an increase in T or a decrease in n(HCl)/n(O2). With a decrease in F-HC10/W, HCl conversion increases while the HCl reaction rate decreases. After chemical equilibrium, HCI conversion decreases with an increase in T and n(HCl)/n(O2), or a decrease in F-HC10/W. The kinetic model that assumes O-2 adsorption is the rate-controlling step can suitably describe the reaction behavior of HCl catalytic oxidation over a Cu-based composite catalyst.
