摘　　要：在实验室内对蜂窝状V2O5-WO3/TiO2基脱硝催化剂的组成及制备工艺进行了研究,介绍了催化剂的制备过程,包括制备条件、干燥和焙烧时间等,以及催化剂性能测试.微观结构表征和脱硝性能试验结果表明:制备的蜂窝状催化剂比表面积较大,机械强度较好;NO脱除率较高,选择性好;NH3逃逸量及SO2氧化率均能达到商业要求.The composition and preparation technology of V2O5-WO3/TiO2 based honeycomb catalysts for denitration were investigated in the lab. The preparation process of the catalysts, including the preparation conditions, drying and calcination time, was introduced while the catalystic performance evaluated. Results of both the microstructure characterization and denitration performance experiments show that, the prepared honeycomb catalysts have larger BET surface area, better mechanical strength, higher NO removal efficiency and good selectivity. The NH3 slip and SO2 oxidation rate can both meet relevant industrial application requirements.
