一种低温抗SO2的MnxSby/PG型SCR脱硝催化剂及其制备方法
摘要：
本发明公开了一种低温抗SO2的MnxSby / PG型SCR脱硝催化剂，由以下各组分组成：活性组分：MnOx，占催化剂0.5-4wt%；助剂：Sb2O5，占催化剂0.5-5wt%；载体：凹凸棒PG，占催化剂85-95wt%；成型材料：玻璃纤维和甲基纤维素，占催化剂2-6wt%，玻璃纤维与甲基纤维素质量比为(4-30):1；润滑剂：硬酯酸和乳酸，占催化剂0.1-1wt%，硬酯酸与乳酸的质量比为1:(2-10)。本发明还公开了制备方法。本发明催化剂不仅具有高效的低温SCR的脱硝效率，而且表现出较强的抗SO2性能，能够在较低的反应温度下达到较高的催化剂反应活性，并抑制催化剂SO2中毒现象。
摘要（英）：

The invention discloses a low-temperature SO2-resistant MnxSby/PG-type SCR denitration catalyst. The catalyst comprises 0.5-4wt% of MnOx as an active ingredient, 0.5-5wt% of Sb2O5 as an assistant, 85-95wt% of attapulgite PG as a carrier, 2-6wt% of glass fibers and methyl cellulose as molding materials, wherein a mass ratio of the glass fibers to the methyl cellulose is (4-30): 1, and 0.1-1wt% of stearic acid and lactic acid as lubricants, wherein a mass ratio of stearic acid to lactic acid is 1: (2-10). The invention also discloses a preparation method of the catalyst. The catalyst has high efficiency low-temperature SCR denitration efficiency, strong SO2-resistant performances and high catalyst reaction activity at a low reaction temperature and can inhibit catalyst SO2 poisoning.
