Decomposition of CFC and Halon waste gases in normal-pressure plasma reactors

The normal-pressure decomposition of CF2Cl2 and CF2ClBr in air by non-equilibrium plasma was studied. The pressure of CF2Cl2 and CF2ClBr was 2.67x103Pa, added the dry air to 1.01 x 105 Pa, discharged by corona or DBD, 11.5% of CF2ClBr was decomposed by corona after 120s discharge, more than 85% of CF2Cl2 and 95% of CF2ClBr was decomposed by DBD after 10s discharge respectively. The main products were CF2O, Cl2 and Br2.
