Abstract The paper discusses the effectiveness of two catalytic systems in destroying specific organic compounds (jet fuel components, chlorinated solvents). (NOTE: Catalytic incineration is used to destroy volatile organic compounds contained in air emissions from a variety of industrial processes.) The test vapor streams consisted of low concentrations (3 to 200 ppmv) of mixtures which represented emissions from air strippers used to treat contaminated groundwater at U.S. Air Force bases. One system employed a metal oxide catalyst in a fluidized bed. The other system used a fixed-bed proprietary catalyst, supplemented with UV light and ozone injection. Destruction efficiencies for the fluidized-bed reactor were between 97 and 99% at sufficiently high catalyst temperatures (500 C). Mixture composition, air-to-gas ratio, and space velocity affected destruction efficiency minimally. Destruction efficiencies for the UV-catalytic oxidizer ranged from 16 to 67% without ozone addition. With ozone, complete oxidation of the text mixture components was achieved, but high concentrations of several unidentified reaction products was observed.
