- Abstract
The generation of atoms and radicals by the equilibrium thermal dissociation of oxygen and the same process involving water vapor are similar in terms of the reactive-species yield and energy consumption. The energy input into the generation of atoms and radicals is the smallest at 4500 K; about 70% of the energy is spent directly for the breaking of chemical bonds. From the calculations of the kinetics of oxygen atom recombination, it follows that cooling at a rate higher than 107 K/s makes it possible to achieve considerable deviations from the equilibrium atom concentration. The lifetime of atoms in cooling thermal plasma is estimated at 10−5 s. It has been established experimentally that a thermal plasma jet plunging into the water bulk generates hydrogen peroxide. The totality of factors affecting the hydrogen peroxide accumulation rate can be represented in as a generalized parameter, specifically, the atomic oxygen feed rate.
