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。该方法以氧化物负载的稀土氧化物和过渡金属氧化物为燃烧催化剂,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 chloroarene pollutants in environment by complete catalytic combustion. The method comprises the following steps of: introducing an oxide-supported rare earth oxide and a transition metal oxide serving as combustion catalysts and air serving as an oxidant into a reactor; completely combusting the chlorine-containing volatile arene under the action of the catalysts; converting the chlorine-containing volatile arene into carbon dioxide, hydrogen chloride and chlorine gas; and absorbing the complete combustion tail gas (acid gases such as the hydrogen chloride, the chlorine gas and the like) by using weak aqueous alkali and emptying the tail gas. The method has the advantages of high activity of the used catalysts, no byproduct, no secondary pollution, high chlorine poisoning resistance and long service life of the catalysts, and is especially suitable for eliminating halogen-containing organic compound, particularly the volatile chlorine-containing arene pollutants, by low-temperature complete catalytic combustion.
