Thermal-catalytic oxidation, consisting of combined thermal and cataly
tic processes, is proposed as a new method to neutralize waste gases.
A comparison between the proposed two-step thermal-catalytic and catal
ytic neutralization processes is done at temperatures ranging from 350
to 750 K. The efficiency of the neutralization of waste gases that is
obtained by using the thermal-catalytic method is higher, compared wi
th the efficiency of waste gas neutralization by using the catalytic m
ethod. The observed difference ranges from 20 to 10%, as was found for
model waste gas containing ethyl acetate, and from 10 to 5%, as was d
etermined in the case of a toluene imitating toxic component of waste
gases. In addition, the mechanism of the thermal-catalytic process is
studied. The first step of this process, thermal oxidation, is shown t
o influence the subsequent one, catalytic oxidation.
