A recuperative reactor with a fixed porous bed for oxidization of organic
impurities contained in air has been simulated. This reactor represents
a system consisting of two coaxial tubes filled with a porous carcass mix.
The influence of the dimensions of the reactor, the heat losses through its
side wall, and the diameter of the filling-material balls on the maximum
temperature realized in it, the efficiency of recuperation, and the position
of the combustion front has been investigated. It has been established
that the maximum temperature of the indicated reactor changes nonmonotonically
with increase in the heat exchanges between its side wall and the environment.
The parametric-investigation results obtained can be used for optimization of the 
design of recuperative reactors.
