ABSTRACT:
The present invention relates to processes for converting a mixed alcohol feedstock, including methanol and a higher alcohol, to olefins such as ethylene, propylene, and the like. In addition, the olefins produced by the oxygenate-to-olefin reaction system can then be used as monomers for a polymerization of olefin-containing polymers and/or oligomers.
