摘要： This invention is directed to a process for converting oxygenate to olefin product at an increased prime olefin selectivity (i.e., increased ethylene and/or propylene content) compared to conventional systems. The increase in ethylene and/or propylene content of the produced olefin product is accomplished using a reaction system that has at least two stages. Any number of stages can used in the entire process, as long as there are at least two stages in series and the temperature of any subsequent stage in series is lower than that of the preceding stage.

摘要： 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.

摘要： The invention provides low metal content molecular sieve catalyst compositions, processes for making such catalysts, and processes for using such catalysts in the conversion of an oxygenate into one or more light olefins. Preferably, the catalyst composition comprises a matrix material having a low metal content. By utilizing matrix materials having low metal contents, the amount of metal-catalyzed side reaction byproducts formed in a reaction system, particularly in an oxygenate-to-olefin reaction system, can be advantageously reduced.
