摘　　要：论述了一种新颖的SCR蜂窝式脱硝催化剂耐磨损性能模拟试验装置,并利用该装置对六种规格的SCR蜂窝式脱硝催化剂进行了耐磨损性能的试验研究。研究表明:该模拟装置能较逼真地模拟电厂实际运行的飞灰条件,其工作原理和设计思路可靠有效。随着催化剂的开孔率增加,催化剂耐磨损强度和耐磨损性能提高;磨损剂消耗量和试验时间增加,都会增加催化剂的磨失量,对催化剂的耐磨损性能带来不利影响。A novel device for testing SCR honeycomb catalysts abrasion performance was made and used to test six types of SCR honeycomb catalyst. The experimental results show that the device can truly simulate actual fly ash op-erating condition of power plant. So the principle and design of the device was reliable and available. The study also indicated that the abrasion performance of SCR honeycomb catalysts will be improved with opening ratio of catalyst. To increase consumption of abrasion agent and testing times will bring a negative impact on abrasion performance of catalysts.
