The restriction of emission of volatile organic compounds from industry, pr
oduction and consumption and solvents is often based on combustion processe
s. The total combustion of organic mixtures to CO2 and H2O at high temperat
ures increases the costs of the burning. The problem can be partly solved b
y the use of a suitable catalyst allowing perfect incineration at lower tem
peratures. The catalyst efficiency is different for various types of organi
c compounds and depends on the mechanism of reactions occurring on the cata
lyst surface. The combustions of compound mixtures and commercial thinners
were measured and two types of platinum and oxide catalysts were tested. Mo
nitoring of concentration of organic compounds was carried out by continuou
s recording with a FID detector and by GC-MS; analysis of intermediate comb
ustion products.
