Applications/Examples of results
The primary application of CMC-NH4 is as an SCR denitration catalyst. Carboxymethyl cellulose ammonium (CMC-NH4) is a cellulose derivative in which the sodium salt of the carboxymethyl group is replaced with an ammonium salt, and it is used as an adhesive and binder for special applications. Particularly important is its role in SCR denitration catalysts, where it ensures binding during catalyst formation while suppressing the negative effects on catalytic activity caused by alkali metals such as sodium. Alkali metals have been confirmed to reduce the surface acidity and reducibility of SCR catalysts, inhibiting NH₃ adsorption and NOx conversion reactions. Therefore, CMC-NH4 is positioned as a material that mitigates these deactivation risks.
