    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 invention is directed to a method for preparing microporous aluminophosphate or silicoaluminophosphate molecular sieves having the CHA framework type, the process comprising the steps of a) forming a reaction mixture comprising a source of aluminum, a source of phosphorus, optionally a source of silicon, at least one source of fluoride ions and at least one template containing one or more N,N-dimethylamino moieties, b) inducing crystallization of aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture; c) recovering aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture. The invention also relates to the molecular sieves obtained by this method and to molecular sieve catalyst compositions containing these molecular sieves.
