Novel porous SCR catalyst and preparation method thereof

The invention discloses a novel porous SCR catalyst and a preparation method thereof.The porous SCR catalyst is prepared from, by weight, 100-130 parts of titanium dioxide, 40-70 parts of a porous base material A, 4-22 parts of a porous base material B, 20-40 parts of polyoxyethylene, 4-9 parts of glass fibers, 1-3 parts of a solvent, 0.6-1 part of oleic acid, 0.2-1 part of a lubricant and 20-240 parts of deionized water. Wherein the porous base material A is a powdery porous base material formed by carrying out pre-crushing, bonding, curing, heat treatment and post-crushing on carbon fibers and wood pulp fibers. Porous formation of the SCR catalyst can be realized, and the glass fibers, the spherical crystalline flake graphite and the like are added, so that the porous strength of the SCR catalyst is further improved. 本发明公开了一种新型多孔SCR催化剂及其制备方法，多孔SCR催化剂按重量份包括：钛白粉100-130份，多孔基材A40-70份，多孔基材B4-22份聚氧化乙烯20-40份，玻璃纤维4-9份，溶剂1-3份，油酸0.6-1份，润滑剂0.2-1份，去离子水20-240份，其中多孔基材A是由碳纤维、木浆纤维经前粉碎、粘结、固化、热处理、后粉碎所形成的粉末状多孔基材。本发明能实现SCR催化剂的
