摘要： 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.

摘要： This invention is to a process for separating condensed water and entrained solids from an olefin stream so that fouling of the separation equipment by the entrained solids is reduced or eliminated. The process involves injecting an antifouling agent into a water condensing or quench system in an amount to maintain a zeta potential of fouling liquid and a zeta potential of the surface of the quench system both in a positive range or both in a negative range.

摘要： A method for producing 3-methyl-2-pentene which is substantially free of any other C.sub.6 olefin, except 2-ethyl-1-butene, by first producing a stream that contains 2-ethyl-1-butene from the trimerization of ethylene, and second by recovering the 2-ethyl-1-butene as 3-methyl-2-pentene via etherification, separation of the ether, and decomposition of the ether back to predominantly 3-methyl-2-pentene with some 2-ethyl-1-butene.
