Thermocatalytic oxidation of organic compounds in gaseous discharges

Abstract

This article examines results obtained in a kinetic study of the oxidation of a model mixture of air with methyl methacrylate vapor, or iron-chromium catalyst at 100-450 C under steady-state conditions. Indicates that the thermocatalytic oxidation of methyl methacrylate vapor in mixture with air at 100-400 C proceeds in the kinetic region with a high degree of oxidation, ensuring that the maximum permissible concentration will not be exceeded. Points out that because of the relatively low oxidation temperature that is required, the treatment of the discharge can be made more economical in terms of energy costs. Notes that at 400-500 C, the process goes forward in the transition region, since external diffusion factors begin to be imposed at temperatures above 400 C. Concludes that the proposed mathematical model offers a means for scientifically based selection of the most economical region for realization of commercial processes in treatment of discharges.
