The organic waste gases emitted by the petrochemical, light industry, plastics, printing and coating industries are common pollutants, organic waste gases often contain hydrocarbon compounds (aromatic hydrocarbons, alkanes, olefins) , oxygen-containing organic compounds (alcohols, ketones, organic acids, etc.) , nitrogen, sulfur, halogen and phosphorus-containing organic compounds. The catalytic incineration method is to oxidize the waste gas containing organic pollutants into carbon dioxide and water at lower temperature under the action of platinum and palladium catalysts. Because of the low ignition temperature, it is an ideal method to treat organic pollutants by catalytic reaction (without open fire) .
