V2O5-WO3/TiO2脱硝催化剂的制备及其性能

Study on the Preparation and Property of SCR Catalyst V2O5-WO3/TiO2

  • 摘要: 对选择性催化还原脱硝用催化剂V2O5-WO3/TiO2的制备工艺进行了实验研究. 采用溶胶-凝胶法制得TiO2凝胶,对凝胶进行不同条件下的干燥和煅烧处理,然后通过浸渍法在TiO2上依次负载WO3和V2O5,最终得到V2O5-WO3/TiO2催化剂. 结果表明,TiO2凝胶的处理温度对催化剂结构和脱除NO的性能有一定的影响,TiO2凝胶干燥温度为105 ℃时制得的催化剂活性较高,在实验条件下NO脱除率最高可达98.3%.
