Abstract
This invention is directed to a process for producing olefin product from an oxygenate feed that includes dimethyl ether (DME). The process uses an olefin forming catalyst that contains a porous crystalline material, preferably a porous crystalline aluminosilicate molecular sieve material. The process produces high quantities of light olefin (i.e., ethylene, propylene, and mixtures thereof).
