摘要
研制出用于催化氧化废气中挥发性有机化合物 ( VOC)的非贵金属氧化物催化剂。在固定床上 ,处理含醋酸丁酯的模拟气 ,考察了空速、浓度等因素对催化剂活性的影响及催化剂的耐热性能。当空速为 50 0 0 h- 1、进气温度为 2 2 0℃、醋酸丁酯质量浓度为 2 .4～ 5.8g/m3时 ,醋酸丁酯的去除率 >98% ,而且该催化剂具有较高的热稳定性。
A catalyst based on non noble metal oxides for catalytic oxidation of volatile organic compounds (VOC) in waste gas has been developed.In the experiments a simulated gas containing butyl acetate was treated in a fixed bed reactor to investigate the influences of space velocity and reactant concentration on the activity and the thermal stability of the catalyst.The results show that the removal efficiency of butyl acetate is over 98% under the conditions of 5000 h -1 of space velocity,220℃ of reaction temperature and 2.4 ~5.8 g/m 3 of butyl acetate concentration in the simulated gas;and the thermal stability of the catalyst is good.
