Catalytic oxidation of dichloromethane and toluene over platinum alumite catalyst

Abstract

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 CH 2Cl 2 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 CH 2Cl 2, although it can suppress CH 3Cl formation because the steam generated from the catalytic combustion of toluene suppresses the formation of CH 3Cl from CH 2Cl 2. High concentrations of CH 2Cl 2 have a negative effect on the catalytic combustion of toluene.
