    Abstract: A process is described 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 having an uptake of carbon dioxide at 100° C. of at least 0.03 mg/m2 of the metal oxide. 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.

    Abstract: Methods are provided for producing an alcohol-containing pyrolysis product. Initially, a hydrocarbon feedstock is pyrolyzed in the presence of a catalyst system, the catalyst system comprising a basic metal oxide catalyst and a hydrogenation metal catalyst. A pyrolysis product is produced that contains at least one alcohol. The basic metal oxide catalyst is comprised of at least one metal from Group 2, Group 3 including Lanthanides and Actinides, or Group 4 of the Periodic Table of Elements, and the supported hydrogenation metal catalyst is comprised of at least one metal from Group 6 or Groups 8-10 of the Periodic Table of Elements.
