Catalytic oxidation of dichloromethane and toluene over platinum alumite catalyst

Catalytic oxidation technology is one of the most promising technologies for the reduction of volatile organic compound (VOC) emissions. It is very necessary to study the catalytic oxidation of mixture of VOCs and volatile organic compounds (CVOCs), because VOCs are always emitted accompanying with CVOCs. Hence, the catalytic oxidation reaction of toluene and CH2Cl2 is explored on a platinum alumite catalyst in this work. The results show that the addition of toluene has no effect on the decomposition of CH2Cl2, although it can suppress CH3Cl formation because the steam generated from the catalytic combustion of toluene suppresses the formation of CH3Cl from CH2Cl2. High concentrations of CH2Cl2 have a negative effect on the catalytic combustion of toluene.
