VERFAHREN UND VORRICHTUNG ZUR VERRINGERUNG VON NEBENPRODUKTEN IN EINEM METHANOL ZU OLEFIN REAKTORSYSTEM |
摘要 |
<p>Disclosed is a method and apparatus for reducing the amount of metal catalyzed side-reaction byproducts formed in the feed vaporization and introduction system of a methanol to olefin reactor system by 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.</p> |
