Title:
金属イオン担持ゼオライト触媒の再生方法
Document Type and Number:
Japanese Patent JP7293622
Kind Code:
B2
Abstract:
To provide a method for regenerating catalysts as a metal ion-carrying zeolite catalyst, by reconstructing metal clusters and metal particles, which are aggregated metal ions by use as a catalyst, into original metal ions and redispersing the metal ions onto acid points of the zeolite.SOLUTION: There is provided a method for regenerating a metal ion-carrying zeolite catalyst in which a used metal ion-carrying zeolite catalyst is in contact with a gas having an oxygen content of 4 to 25% at the temperature of 480 to 650°C.SELECTED DRAWING: None
