钙钛矿型催化剂去除VOC的性能研究

Preparation of Supported Perovskite Catalysts and Its Performance for the Catalytic Combustion of VOCs

挥发性有机化合物（VOCs）是大气的主要污染物之一,催化燃烧法是目前研究的处理VOCs的有效方法之一。本研究基于VOCs的催化燃烧进行,用浸渍法制备了性能优良的负载型稀土钙钛矿催化剂La0.8Sr0.2MnO3,以气相色谱为检测手段,用常压气体流动评价装置研究该催化剂对低浓度（100~1000mg/m3）VOC（甲苯）催化燃烧的去除效果。

VOCs is one of the main source of the air pollution,catalytic combustion is one of the effective methods of disposing the VOCs.The study based on the catalytic combustion of the VOCs,La0.8Sr0.2MnO3 of supported perovskite catalysts were prepared by way of impregnation,which was proved on eximious performance.With the Gas Chromatogram,used the normal press air fluxion evaluation equipment to investigate the catalyst about its conversion effect of catalytic combustion for simple VOC（dimethyl benzene,styrene,chlorobenzene） and mixed VOCs in a low concentration（100~1000 mg/m3）.
