Title: ZEOLITE HAVING SPECIFIC RATIO OF DIVALENT COPPER IONS SUPPORTED THEREON, AND PREPARATION METHOD THEREFOR AND CATALYST COMPOSITION COMPRISING SAME
Abstract:
The present invention relates to zeolite having, in a specific ratio, Cu2+ (α) and Cu2+ (β), which have different NO association rates, supported thereon, wherein the zeolite is chabazite(CHA)-type zeolite, especially CHA-type zeolite in which divalent copper ions having, after exposure to NO (nitrogen oxide) for 180 seconds, 80% or higher of an NO adsorption area ratio of Cu2+ (α)/ Cu2+ (β) are supported. In addition, the present invention relates to a method for preparing ion-exchanged zeolite in a slurry state, and a catalyst comprising the specified CHA-type zeolite.
