The report gives results of a determination of the effectiveness of catalytic oxidation for destroying vapor-phase chlorinated hydrocarbons. The study was conducted on two pilot-scale catalytic incinerators: one employed a metal oxide catalyst in a fluidized-bed configuration; and the other, a fixed-bed proprietary catalyst, supplemented with ultraviolet (UV) light and ozone injection. Both systems were tested under a variety of temperature and space velocities. The test vapor streams consisted of low concentrations (3-200 ppmv) of mixtures of organic compounds, and included three streams that represented emissions from air strippers used to treat contaminated groundwater at U.S. Air Force bases. Study results showed that the fluidized-bed catalytic incinerator was capable of achieving total organic destruction efficiencies of greater than 98%. The UV/ozone catalytic incinerator failed to achieve high destruction efficiencies: with ozone injection, total destruction was 75%; and without ozone, the maximum destruction efficiency was 64%.
