Ozonocatalytic Oxydation of Contaminants

The addition of small quantities of ozone to an air stream passing through a catalytic oxidizer has three effects: the temperature necessary for catalitic oxidation is decreased from 450-600 K to 330-350 K, working time of catalyst is increased, and the suite of complex oxidation of all complex organic compounds that can be oxidized is increased.

Experiments have shown ozonocatalytic oxidation of xylene, toluene and carbon monoxide to water and carbon dioxide. The investigations ware carryed out with various oxide catalysts, at several temperatures with various gas mixtures, and at various flow rates. It was shown 1) that the process of oxidation was associated with the formation of atomic oxygen from ozone; 2) that cobalt and copper oxides have maximum activity, and 3) that optimal conditions are in the range T=333-343 K, W=20000h^-1.
