Simple physical mixing of zeolite prevents sulfur deactivation of vanadia catalysts for NO x removal

V-based NO x abatement systems are limited in operating at low-temperatures due to the formation of ammonium bisulfate that blocks active sites of catalysts. Here, the authors report that physically mixed zeolites trap ammonium bisulfate in their micropores, thereby protecting the catalysts.
