The heat released when organic substances are adsorbed on activated carbon is called exothermic reaction, and in addition, once some reactive compounds are adsorbed on the activated carbon, chemical oxidation reaction or polymerization reaction occurs on the surface of the activated carbon, the reaction is also exothermic, and the exothermic amount is exponentially increased compared with the ordinary adsorption exothermic amount, and when the heat released by the oxidation exothermic reaction cannot be rapidly dissipated, the temperature may be increased in the bed to the temperature at which the activated carbon and the organic substances adsorbed on the activated carbon are ignited.
