Abstract

The catalytic oxidative decomposition of CFCs containing two carbon atoms was investigated in the presence of hydrocarbons (C1-C4 alkanes) over silica and various acidic metal oxides. It was found that CFC-115 was the most difficult to be decomposed among CFC-113, CFC-114, and CFC-115, and that γ-alumina was the most active catalyst. The CFC-115 conversion over γ-alumina was lower in the presence of methane than in the presence of the other hydrocarbons. In addition, the activities of γ-alumina-supported metal and metal oxide catalysts were investigated for the oxidative decomposition of CFC-115 in the presence of n-butane. Tungsten (VI) oxide and vanadium (V) oxide catalysts exhibited the highest activity.
