CN106268773A 一种薄壁宽活性温度窗口脱硝催化剂及其制备方法 无效 - 驳回

一种薄壁宽活性温度窗口脱硝催化剂及其制备方法
摘要：
本发明提供了一种薄壁宽活性温度窗口脱硝催化剂，其特征在于：包括活性组分前驱体、助剂前驱体、载体、添加剂，其余为去离子水；所述的助剂前驱体为仲钼酸铵，在最终催化剂中以MoO3形式存在，其在最终催化剂中的质量百分比不高于10％。本发明的脱硝催化剂壁厚为0.6-1.1mm，孔数可为16孔×16孔、18孔×18孔、20孔×20孔、21孔×21孔、22孔×22孔等，开孔率在75％-85％之间，具有SO2氧化能力随壁厚变薄而降低，磨损率降低，脱硝催化剂宽温度窗口内(250-420℃)效果更好的优点。
摘要（英）：

The invention provides a thin-wall wide active temperature window denitration catalyst. The thin-wall wide active temperature window denitration catalyst comprises an active component precursor, an accessory ingredient precursor, a carrier, an additive, and the balance deionized water; the accessory ingredient precursor is ammonium paramolybdate, existing form of the accessory ingredient precursor in the thin-wall wide active temperature window denitration catalyst is MoO3, and mass content of MoO3 in the thin-wall wide active temperature window denitration catalyst is 10% or lower. The wall thickness of the thin-wall wide active temperature window denitration catalyst ranges from 0.6 to 1.1mm; pore number is 16*16, 18*18, 20*20, 21*21, and 22*22 pores; pore ratio ranges from 75 to 85%; SO2 oxidation capacity is reduced with reduction of the wall thickness, wear rate is reduced, and effect in a denitration catalyst wide temperature window (250 to 420 DEG C) is excellent.
