RESUMO

The plasma destruction of methyl mercaptan and dimethyl sulphide has been studied in both nitrogen and air gas streams with a non-thermal, atmospheric pressure discharge using a packed bed of BaTiO3 beads. Destructions in excess of 85% can be achieved for pollutant concentrations of 30 to 100 ppm with energy costs in the order of 75 to 200 kWh/kg. The detected end-products of the processing are H2S, HCN, NH3 in a N2 stream and SO2, CH2O, CO and CO2 in air. The implications for odour control are discussed.
