VOC/Odor Treatment Catalyst
Catalytic combustion method is well known as one of the means of exhaust gas treatment for VOC which may cause air pollution, odor problem. It is oxidation reaction between flammable gases such as VOC and air. In case the gases are hydrocarbons or organic compounds containing oxygen in the structure, they are converted into non-harmful CO2 and H2O by oxidation reaction and it generates heat of reaction for heat recovery.
