摘要： This invention concerns the field of environmental protection and can be used to clean industrial waste gases containing products that cause resin formation which fouls catalysts. It is proposed to clean industrial waste gases of aromatic and aliphatic compounds at 120-160 ° C. by means of passing waste gases first through a catalytic composition consisting of a guard bed (to protect the palladium catalyst) with a specific surface 0.2-1.0 m2·g−1, which is initially roasted at 800-1,350° C. and second through a palladium catalyst bed (0.1-3% palladium, deposited on an active aluminum oxide). The proposed method makes it possible to clean industrial waste gases of harmful substances (for example, methanol, cumene) with a degree of destruction not less than 97-98% in the presence of aromatic hydroperoxides which cause resin formation and catalyst fouling on other catalytic systems.
