Abstract.Chemical kinetics of thermal conversion process of carbon-containing media at high temperature (2000 K ≤T ≤5000 K) processing in the chamber of the reactor using a plasma jet as the oxidant vapor was studied. Rate of chemical reactions was calculated by procedure set out for defining kinetic constants of the process of coal-water fuel gassing. Impact of gaseous medium temperature in the chamber on the time of full conversion of fuel carbon particles was specified. As an example, parameters of process of coke particle (size (5 ÷ 20) ∙ 10-5 m) gasification are calculated with coefficient of excess oxidant α = 0,45 and fuel consumption mT = 100kg / h. Expediency of the steam-plasma gasification process at temperature of gas in the reactor chamber up to 3000 K is grounded.

Keywords: chemical kinetics, vapor-plasma processing, hydrocarbon fuel, carbon-containing media, gasification process.
