ABSTRACT:
A process for converting noxious nitrogen oxides present in gaseous effluent to N.sub.2 comprising reacting the gaseous effluent with an effective amount of reducing agent, e.g., ammonia, in the presence of a catalyst structure comprising a film of interconnected zeolite crystals bonded to a substrate, said catalyst structure being characterized by a value r representing the mg of zeolite/cm.sup.2 of substrate surface and a value e representing the coating efficiency as mg of bonded zeolite/mg of YO.sub.2 initially in the synthesis mixture, wherein r is at least 0.5 and e is at least 0.05.
