摘要：
Catalytic compositions based on zeolite Y for use in the treatment of oxygenated effluents containing NO.sub.x, comprising 70 to 90% of zeolite NH.sub.4 Y having a specific surface between 750 and 950 m.sup.2 /g exchanged to cupric ions, wherein the copper content is between 2 and 12% relative to the weight of the zeolite; and 10 to 30% of a binder are disclosed. Processes for the preparation of such catalytic compositions are also disclosed.
