【Abstract】 The catalystic oxidation activities of catalysts of non rare metal oxides for VOCs were investigated,with supporter of alveolate ceramic coated activating alumina.The influence of temperature,space velocity and VOCs concentration on conversion and the stability of catalysts were observed.The results show that conversion of VOCs is higher than 98%,at low temperature.Under the condition of space velocity 10 000～25 000 h -1 and VOCs concentration 1 05～7 60 g/m 3, the catalysts have relatively high adaptability.The catalysts can resist the high temperature impact up to 950℃.更多还原
