【摘要】 挥发性有机物是大气污染的主要来源之一,给人们的身体健康带来很大危害。对挥发性有机物治理的主要技术——催化燃烧进行了介绍,指出催化剂是催化燃烧技术的核心,并介绍了一种Ce-Zr基催化燃烧催化剂的制备技术。采用共沉淀方法制备了Ce-Zr复合氧化物,以堇青石陶瓷蜂窝作为载体,运用浸渍-涂附技术制备了催化剂,并利用苯系气体作为原料气,对催化剂进行了性能评价。更多还原

【Abstract】 VOCs (Volatile Organic Compounds) are one of the main pollution sources that contaminate air, and VOCs could do a lot of harm to environment and human health. The main technologies for the removal of VOCs from polluted air, the methods of catalytic combustion, were reviewed, and catalysts plays an im- portant role in the technologies of catalytic combustion . The Ce-Zr mixed oxides were synthesized by co-precipitation method, and the cordierite ceramic honeycomb as the catalyst support, the catalyst was prepared by dip-coating method, the activity of the catalyst was studied.更多还原
