CATALYTIC REDUCTION OF NITROGEN OXIDE EMISSIONS WITH MCM-49 AND MCM-56

摘要

MCM-56 and MCM-49 have been demonstrated to be effective catalysts for the reduction of nitrogen oxide (NOx) emissions in a net oxidizing environment such as Selective Catalytic Reduction or lean burn engine exhaust applications. MCM-56 and MCM-49 can be utilized as a component of a spherical or cylindrical catalyst particle or as a wash coat on a ceramic or metallic monolith. Optionally, a transition metal such as copper, can be added to the catalyst for improved activity.
