CATALYSIS-ASSISTED PLASMA TECHNOLOGY FOR CARBON-TETRACHLORIDE DESTRUCTION

Single-stage, catalysis-assisted plasma technology is a new concept de veloped to decompose carbon tetrachloride (CCl4), one of the greenhous e gases, and to reduce the reaction byproducts at the same time. A lab oratory-scale plasma reactor used a packed-bed reactor with 1-mm spher ical BaTiO3 pellets. The configuration employed a unique one-stage cat alysis/plasma process in which the BaTiO3 pellets were coated or impre gnated by active catalysts such as Co, Cu, Cr, Ni, and V. The power su pply used for these experiments was either a 50-Hz neon transformer or an 18-kHz inverter neon transformer, Enhancement of the CCl4 destruct ion and the conversion of by-product CO to CO2 were demonstrated using Ni catalyst in the one-stage plasma reactor.
