A non-thermal, atmospheric pressure plasma utilising a dielectric packed bed was used to study the destruction of dichloromethane, CH 2 Cl 2 , (DCM) in gas streams of nitrogen with the presence of catalysts. The effect of plasma-assisted catalysis was investigated in two configurations; one where the catalyst was incorporated into the packed bed itself and the other where the catalyst was downstream of the plasma. The combination of plasma and a catalyst allowed improved destruction of DCM. γ-Al 2 O 3 in a one-stage reactor configuration was the most successful in terms of the total destruction of DCM as well as providing the best result in the two-stage reactor configuration compared with the eight catalysts chosen which included alumina, TiO 2 and various zeolites. Products as detected by FTIR were CO, CO 2 , HCN, HCl and H 2 O with the by-product of N 2 O. The nature of the catalyst plays a vital role with respect to the effectiveness of DCM destruction and the selectivity of the end-products.
