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.
催化氧化技术是减少挥发性有机化合物(VOC)排放最具前景的技术之一。研究VOCs与含氯挥发性有机化合物(CVOCs)混合物的催化氧化非常必要,因为VOCs总是伴随着CVOCs排放。因此,本工作在铂铝酸盐催化剂上探索了甲苯与二氯甲烷的催化氧化反应。结果表明,甲苯的添加对二氯甲烷的分解没有影响,尽管它可以抑制氯甲烷的形成,因为甲苯催化燃烧产生的蒸汽抑制了二氯甲烷生成氯甲烷。高浓度的二氯甲烷对甲苯的催化燃烧有负面影响。
