摘要： A process for regenerating a zeolite catalyst comprises the following stages: (I) Heating a partially or completely deactivated catalyst to 250-600null C. in an atmosphere which contains less than 2% by volume of oxygen, (II) treating the catalyst at from 250 to 800null C., preferably from 350 to 600null C., with a gas stream which contains from 0.1 to 4% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof, and (III) treating the catalyst at from 250 to 800null C., preferably from 350 to 600null C., with a gas stream which contains from more than 4 to 100% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof.
