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 DEG 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 DEG C, preferably 350 to 600 DEG 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 DEG C, preferably 350 to 600 DEG 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. %.

Abstract: The invention relates to a moulded body comprising an inert support and at least one porous oxidic material applied to said support. The inventive moulded body is obtained by applying a mixture containing the at least one porous oxidic material and at least one metal acid ester or a hydrolyzate thereof or a combination of metal acid esters and hydrolyzate thereof to the inert support.
