The influence of amount of copper of modified vermiculites on catalytic properties in SCR-NH3

Abstract

Vermiculite was prepared by modifications with nitric acid, pillaring with Al oligocations and polymer (polyamide), impregnation with Cu. Obtained products were used as catalysts in SCR-NH3 process. All modifications increased catalytic performance compared to base vermiculite which was used as a reference. Sample pillared with polymer and impregnated with 5%wt. Cu showed best catalytic properties in the process, compared to other polymer and Cu modified samples.
