摘要

采用溶胶凝胶法在陶瓷过滤器上负载TiO2载体

再负载脱硝活性组分V2O5

制备出具有催化功能的V2O5-TiO2陶瓷催化过滤器；采用扫描电子显微镜、X射线衍射仪、化学吸附仪等手段对制备的陶瓷催化过滤器进行了表征；不考虑飞灰颗粒影响

在模拟烟气条件下对制备的陶瓷催化过滤器进行了脱硝性能研究

分析了TiO2负载次数和负载量、V2O5负载量、表面速度、氨氮比等对陶瓷催化过滤器脱硝性能的影响，并考察了表面速度以及氨氮比对陶瓷催化过滤器脱硝性能的影响。结果表明:脱硝催化剂均匀负载在陶瓷过滤器上；负载1次TiO2载体(即TiO2质量分数为3%)可以获得最大的过滤器比表面积

有利于负载活性组分；温度为340 ℃

烟气流量为0.5 L/min

V2O5负载量为10%时陶瓷催化过滤器的脱硝活性最高

达到80%左右。该结果为进一步研究和优化陶瓷过滤器负载脱硝催化剂提供了依据。
