ABSTRACT OF THE DISCLOSURE Industrial fumes or waste gases containing combustible noxious materials are preheated and passed upwardly through a bed of particulate oxidation catalyst comprising chromic oxide on alumina or other suitable inert support. Catalytic com- bustion of the combustible materials is effected, and the pollutant-free gas is discharged to the atmosphere. The particle size or the catalyst is relatively coarse, and the gas velocity is sufficient to agitate or fluidize the bed. The hardness of the catalyst is such that only limited attrition occurs, which assists in keeping the catalyst surface clean, and the catalyst loss in the effluent gas is less than one pound per million standard cubic feet of gas treated.
