    摘要: A method is provided for converting oxygenates, e.g., methanol, to olefins, e.g., ethylene and propylene, comprising contacting said oxygenates and an aromatics co-feed, e.g., xylenes, with a framework gallium-containing molecular sieve catalyst comprising pores having a size ranging from about 5.0 Angstroms to about 7.0 Angstroms, e.g., ZSM-5, under production conditions effective to produce olefins. A catalyst composition is also provided, comprising a ZSM-5 zeolite-bound ZSM-5 zeolite having a bound zeolite of framework Ga-containing zeolite having a Si/Ga molar ratio ranging from 5 to 500 and a binder of Ga-modified, e.g., Ga-exchanged and/or Ga-impregnated, zeolite having a Si/Ga molar ratio ranging from 5 to ∞.

    摘要: A process for reforming wherein ethylbenzene formed during the reforming is converted to xylenes. The process is carried out by reforming a feed containing precursors of ethylbenzene with a reforming catalyst under conditions effective to reform said feed; wherein the reforming catalyst is contained in a reactor which contains a second catalyst effective under said conditions to convert ethylbenzene to xylenes. The resulting product contains reduced amounts of ethylbenzene and increased amounts of xylenes.

    摘要: A process for selectively producing para-xylene from a feedstock enriched in C8 isoalkanes and/or isoalkenes is disclosed. The feed is contacted with Group VIII metal loaded molecular sieve catalyst of low acidity under dehydrocyclization conditions wherein the molecular sieve has a channel size ranging from about 5-8 Angstroms and a 10 to 12 membered ring structure containing at least two elements selected from the group consisting of Si, Al, P, Ge, Ga and Ti.
