Process for producing light olefins by using a ZSM-5-based catalyst

Abstract

The present invention relates to a catalyst composition useful in a process for producing lower olefins from a oxygenate feedstream, a process for producing said catalyst composition and a process for producing lower olefins comprising contacting a oxygenate feedstream with the catalyst composition M1-M2-P/ZSM-5 with an oxygenate-comprising feedstream, wherein M1 is one or more basic species, M2 is one or more redox elements selected from Groups 6-8 of the Periodic Table of Elements and Sn and P is phosphorus, wherein said basic species is a molecular entity forming a weak Lewis base and/or a weak Bronsted base in the catalyst composition. In addition thereto, the present invention relates to an integrated process for producing lower olefins from a feedstream comprising hydrocarbons.
