摘　　要：考察了助剂改性对载体性能的影响，助剂的加入量达到3%~5%左右，有利于催化剂脱氮活性提高。分析了焙烧温度对催化剂性能的影响，适宜的焙烧温度为基准-100℃~基准温度。以蜡油为原料，在压力14.0 MPa、空速1.4 h-1、氢油比800∶1的条件下，自制剂的反应温度比对比剂低5℃，整体性能明显优于对比剂。The influence of cocatalyst modification on carrier property is investigated,The cocatalyst addition up to about 3%~5%is beneficial to the improvement of catalyst denitrification activity. The influence of the calcination temperature on catalyst performance is analyzed. The proper calcination temperature is standard- 100℃~standard temperature. With waxy oil as raw material,under the pressure of 14.0 MPa,space velocity of 1.4h-1,H2/oil ratio of 800/1,the temperature of self-made agent is 5℃lower than that of contrast agent,and the whole performance is obviously better than contrast agent
