HETEROGENEOUS REACTIONS OF FREE-RADICALS IN THE OXIDATION PROCESSES

The role of heterogeneous reactions of-free radicals in oxidative reactions of different types (homogeneous gas-phase oxidation, stabilized combustion, heterogeneous catalytic oxidation) was analyzed. It was shown that in all cases the apparent kinetic features and the products composition can be determined by the totality of simultaneously proceeding and reciprocally influenced heterogeneous and homogeneous steps of the same nature. Possible mechanism of heterogeneous formation and transformations of free radicals is discussed. The methods used for the studies of heterogeneous reactions of free radicals are characterized.
