摘要:本发明公开了一种完全催化燃烧消除环境中易挥发性氯代芳香烃类污染物的方法。该方法以氧化铈负载的氧化钌为燃烧催化剂,采用作为氧化剂的空气带入反应器,使含氯易挥发性芳香烃在催化剂的作用下完全燃烧,将含氯易挥发性芳香烃转化成为二氧化碳、氯化氢和氯气,完全燃烧尾气可以采用稀碱溶液吸收(氯化氢/氯气等酸性气体)后放空。本发明所用催化剂活性高,无副产物生成,不造成二次污染,抗氯中毒能力强,催化剂寿命长,特别适用于低温完全催化燃烧消除含卤素有机化合物,尤其是易挥发性含氯芳香烃类污染物。

Abstract: The invention discloses a method for eliminating volatile chlorinated aromatic hydrocarbon pollutants in environment through complete catalytic combustion. In the method, cerium oxide-supported ruthenium oxide is taken as a combustion catalyst, and is carried into a reactor by air serving as an oxidant, chlorine-containing volatile aromatic hydrocarbons are completely combusted under the action of the catalyst, and are converted into carbon dioxide, hydrogen chloride and chlorine, and tail gas (acid gas such as hydrogen chloride, chlorine and the like) obtained after complete combustion can be absorbed by a dilute alkaline solution and is discharged. The catalyst is high in activity, byproducts are not generated, secondary pollution is avoided, chlorine poisoning resistance is high, the catalyst is long in service life, and the method is particularly suitable for eliminating halogen-containing organic compounds, particularly the volatile chlorinated aromatic hydrocarbon pollutants, through low temperature complete catalytic combustion.
