ABSTRACT:
Disclosed is a method and system for reducing the formation of metal catalyzed side-reaction byproducts formed in the feed vaporization and introduction system of a methanol to olefin reactor system by forming and/or coating one or more of the heating devices, feed lines or feed introduction nozzles of/with a material that is resistant to the formation of metal catalyzed side reaction byproducts. The invention also may include monitoring and/or maintaining the temperature of at least a portion of the feed vaporization and introduction system and/or of the feedstock contained therein below about 400° C., 350° C., 300° C., 250° C., 200° C. or below about 150° C. The temperature can be maintained in the desired range by jacketing at least a portion of the feed vaporization and introduction system, such as at least a portion of the feed introduction nozzle, with a thermally insulating material or by implementing a cooling system.
