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： An improved process is disclosed for the isomerization of xylenes over a zeolite which may contain a platinum group metal. The improvement resides in the use of ZSM-23 zeolite which exhibits enhanced selectivity which inhibits the production of undesired C.sub.9.sup.+ aromatic transalkylation by-products. ZSM-23 having pores substantially unobstructed by silica, such as that made from a forming mixture containing amorphous precipitated silica as a silica source, has been found to be particularly useful in the process of the present invention.

摘要： This invention relates to efficiently regenerating catalyst particles by minimizing the formation of localized “hot spots” and “cold spots” in a regeneration zone. Specifically this invention relates to a method for controlling regenerator temperature in an oxygenates-to-olefins system, comprising the steps of: contacting an oxygenate feed in a reactor with a catalytically effective amount of molecular sieve-containing catalyst under conditions effective for converting said oxygenate to a product containing light olefins and forming a coked catalyst; contacting a portion of the coked catalyst in a regenerator, having a catalyst bed height (Hc), an inlet height (Hi), and an outlet height (Ho), with an oxygen-containing regeneration medium under conditions effective to at least partially regenerate the coked catalyst; and conducting a portion of the catalyst from the regenerator to a catalyst cooler to form a cooled catalyst portion, wherein Ho is greater than Hi.

摘要： This invention provides a process for limiting the loss of catalyst particles through olefin product streams and regenerator flue gas streams exiting the reaction system. In particular, this invention provides for removing catalyst particles from the reactor using a water stream and from the regenerator using a two step separation process. The two step process involves the use of a catalyst fine separation unit.
