A new active and selective catalyst for the redn. of N oxides to mol. N2 in a super-stoichiometric oxidising atmos., by reducing agents is claimed. The mass compsn. of the active phase of the catalyst system, expressed as percentage wt. of prod. calcined at 1000 degrees C for 4 h (excluding monolith...
