Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in the exhaust gas at a lower temperature. Therefore, catalytic combustion is also called catalytic chemical conversion. Because the catalyst accelerates the process of oxidative decomposition, most hydrocarbons can be completely oxidized by the catalyst at a temperature of 300 ~ 450 ° C.
Compared with the thermal combustion method, catalytic combustion requires less auxiliary fuel, lower energy consumption, and smaller equipment facilities. However, due to the poisoning of the used catalyst, the replacement of the catalyst bed and the high cleaning costs, the promotion and application of this method in the industrial production process have been affected.
