The decomposition of trifluoromethane (CFF3) was carried out using non-thermal plasma generated in a dielectric barrier discharge (DBD) reactor.The effects of reactor temperature,electric power,initial concentration and oxygen content were examined.The DBD reactor was able to completely destroy CHF3 with alumina beads as a packing material.The decomposition efficiency increased with increasing electric power and reactor temperature.The destruction of CHF3 gradually increased with the addition of O2 up to 2%,but further increase in the oxygen content led to a decrease in the decomposition efficiency.The degradation pathways were explained with the identified by-products.The main by-products from CHF3 were found to be COF2,CF4,CO2 and CO although the COF2 and CF4 disappeared when the plasma were combined with alumina catalyst.
