This invention is directed to a process for producing one or more olefins from an oxygenate feed. According to the invention, an oxygenate stream is provided and a recycle stream is added to the oxygenate stream to form a feed stream to an oxygenate-to-olefin conversion system. The recycle stream comprises (i.e., contains) propane and dimethyl ether.
