MODIFIED CATALYST FOR CONVERTING OF OXYGENATES TO OLEFINS

The present invention relates to a new process for producing zeolite-containing catalysts, in which a modification with phosphorus-containing components is carried out, the catalyst obtainable thereby, and its use as catalyst in a process for producing lower olefins from oxygenates. The modification...

Beschreibung
Zusammenfassung:	The present invention relates to a new process for producing zeolite-containing catalysts, in which a modification with phosphorus-containing components is carried out, the catalyst obtainable thereby, and its use as catalyst in a process for producing lower olefins from oxygenates. The modification comprises removing weakly bound phosphorus-containing species by treatment with an aqueous solution.
