Abstract:
1. A process for converting an oxygenate-containing feedstock into one or more olefins in a reactor system including a plurality of fixed bed reactors each containing a catalyst composition comprising a molecular sieve and at least one metal oxide, selected from Group 3 metals, Lanthanide series metals, and Group 4 metals of the Periodic Table of Elements, having an uptake of carbon dioxide at 100° C. of at least 0.03 mg/m 2 of the metal oxide, wherein each reactor is sequentially rotated between at least one operating mode, wherein the catalyst composition in the reactor is contacted with the oxygenate-containing feedstock, and a regeneration mode, wherein the catalyst composition in the reactor is contacted with a regeneration medium.
