| titleOfInvention | Urea scr catalyst based on Ion exchange-Size exclusion |
| abstract | The invention discloses a kind of urea scr catalyst based on Ion exchange-Size exclusion, its preparation process includes: is mixed with water by sieve particle, makes molecular sieve slurry；The activator solution mixing containing copper ion is added, it is thus achieved that mixed slurry in molecular sieve slurry；The pH value of regulation mixed slurry is 8.9 ~ 9.1, keeps mixed slurry alkalescence, stirs 10 hours ~ 30 hours；Active slurry is dried after filtering, calcining；Defibrination after the catalyst powder cooling that will obtain after calcining, it is thus achieved that catalyst slurry, is then coated onto calcining on carrier.The present invention changes active component coating method on carrier, avoid the catalyst activity surface area that coating is uneven, coated weight is not enough, carrier plug-hole the causes reduction that traditional impregnation technology occurs, catalytic performance declines, and exhaust back pressure increases, the drawback that complete-vehicle oil consumption increases. |
