Regenerative catalytic combustion (RCO) is a method of using catalysts to decompose organic waste gases into harmless small molecules such as carbon dioxide and water. Due to the need to consume heat in the reaction, it is called regenerative catalytic combustion method. The RCO device mainly consists of three parts: a purification chamber, a preheating chamber, and a high-temperature gas outlet, with the temperature of the preheating chamber generally ranging from 300 to 600 ° C; The purification room is equipped with a packing layer to adsorb pollutants from organic waste gas; The high-temperature gas outlet is connected to the atmosphere to recover heat.
