Peculiarities of nitrogen oxides interactions with ground vulcanizates of shock-mounted automobile tires inside adiabatic reactor are considered in the article. Impact of dimension and temperature on process of sorption and chemical adsorption is shown. Values of activation energy of nitrogen oxides interactions with ground rubbers are identified.

Kinetic features of interaction between nitrogen oxides and soot of P-234 and P-803 types have been researched volumetrically and gravimetrically. The maximum speed of nitrogen oxides absorption, quantity of reacting nitrogen oxides and activation energy of reaction have been found.
