EFFECT OF THE CONCENTRATION OF A COMBUSTIBLE GAS ON THE LIMITING CRITICAL CONDITIONS OF ITS CATALYTIC OXIDATION

For the case of the cold, relative to a gas mixture, walls of an apparatus and radiation heat transfer, an investigation is made of the dependence of the limiting minimum gas mixture temperatures above which catalytic self-ignition and fi ring of a low-concentration combustible gas on a catalyst particle are possible. The proposed method is based on obtaining the desired dependences in a parametric form. An analysis of the degeneration of critical temperatures and of ignition and extinction diameters is carried out.
