An analytical model and a method for calculating the oxidation of gases in a block automotive neutralizer are given. The method makes it possible to determine the boundary conditions of the physicochemical process, the effect of diffusion in the porous catalyst and its efficiency, the thermal effects of oxidation of carbon monoxide, hydrocarbons and soot. The model is the theoretical basis for predicting the fire dangerous operation of automotive neutralizers at low temperatures in the Arctic.
