Abstract: A process for regenerating a zeolite catalyst comprises the following stages: (I) Heating a partially or completely deactivated catalyst to 250-600° C. in an atmosphere which contains less than 2% by volume of oxygen, (II) treating the catalyst at from 250 to 800° C., preferably from 350 to 600° 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 800° C., preferably from 350 to 600° 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.

Abstract: The invention relates to a method for regenerating a zeolitic catalyst, comprising the following steps: (I) at least one partially deactivated catalyst is heated to a temperature ranging from 250 to 600 ~C in an atmosphere containing less than 2 vol. % oxygen; (II) the catalyst is impinged upon by a gas flow at a temperature ranging from 250 to 800 ~C, preferably 350 to 600 ~C, said gas flow having an oxygen-delivering substance content or an oxygen content or a mixture of two or more thereof ranging from 0.1 to 4 vol. % and (III) the catalyst is impinged upon by a gas flow at a temperature ranging from 250 to 800 ~C, preferably 350 to 600 ~C, said gas flow having an oxygen-delivering substance content or an oxygen content or a mixture of two or more thereof ranging from over 4 to 100 vol. %.
