    摘要: The present invention relates to new methods of making crystalline materials, as well as to new crystalline materials obtainable by such methods, and their use in hydrocarbon conversion processes. In one of its aspects, the invention relates to a method for preparing a crystalline molecular sieve comprising oxides of one or more tetravalent element(s), optionally one or more trivalent element(s), and optionally one or more pentavalent element(s), said method comprising submitting to crystallization conditions one or more sources of said oxides in the presence of at least one organic templating agent R of formula C1C2R1R2N+ A− (I), in which C1 and C2 each independently represent a substituted or unsubstituted cyclohexyl or cyclopentyl group, R1 and R2 each independently represent a methyl group, an ethyl group or a propyl group, or R1 and R2 together with the nitrogen atom they are connected to form a ring containing 5 or 6 atoms, and A represents hydroxyl, fluorine, chlorine, bromine or iodine.

    摘要: Disclosed herein is a method of converting oxygenates to olefins comprising contacting an oxygenate stream with an acidic high silica chabazite catalyst in one or more oxygenate-to-olefins reactors; circulating greater than from 80% of the catalyst to one or more catalyst regenerators to form regenerated catalyst; circulating the regenerated catalyst, preferably the same amount of regenerated catalyst, back to the oxygenate-to-olefins reactor to contact an oxygenate stream; and isolating a stream of olefins from the one or more oxygenate-to-olefins reactors.

    摘要: The present invention relates to processes for converting a mixed alcohol feedstock, including methanol and a higher alcohol, to olefins such as ethylene, propylene, and the like. In addition, the olefins produced by the oxygenate-to-olefin reaction system can then be used as monomers for a polymerization of olefin-containing polymers and/or oligomers.
