Enhanced SCR Catalytic Performance via Modification with Ammonium Carboxymethyl Cellulose: Preparation and Mechanism
As a specialized binder material, ammonium carboxymethylcellulose (CMC-NH4) serves as a core raw material for premium SCR denitrification catalyst production. Ordinary sodium CMC contains alkali metal components that tend to degrade SCR catalysts: these metals will break the catalyst framework and destroy its active reaction points, leading to catalyst failure. Substituting conventional CMC with CMC-NH4 effectively avoids such deactivation problems. Catalysts manufactured with this ammonium-type cellulose deliver remarkably better working efficiency and longer service cycles, helping manufacturers gain stronger market advantages. Furthermore, CMC-NH4 outperforms regular CMC in two critical aspects: it delivers superior binding force during molding, and leaves far fewer ash residues once calcination is completed.
