摘要： In a method of synthesizing a silicoaluminophosphate molecular sieve having 90%+CHA framework type character, a reaction mixture is prepared comprising first combining a reactive source of aluminum with a reactive source of phosphorus to form a primary mixture that is aged. A reactive source of silicon and a template for directing the formation of the molecular sieve can then be added to form a synthesis mixture. Crystallization is then induced in the synthesis mixture. Advantageously, (i) the source of silicon comprises an organosilicate, (ii) the source of phosphorus optionally comprises an organophosphate, and (iii) the crystallized silicoaluminophosphate molecular sieve has a crystal size distribution such that its average crystal size is not greater than 5 μm. The molecular sieve can then preferably be used in a hydrocarbon (oxygenates-to-olefins) conversion process.

摘要： In a method of synthesizing a mostly CHA-type silicoaluminophosphate sieve, a reaction mixture comprises sources of water, silicon, aluminum, phosphorus, and a template. In one aspect, when the reaction mixture Si/Al2 ratio is less than 0.33, crystallization is induced at least 165° C. Advantageously, the sieve so crystallized exhibits a Si/Al2 ratio less than 0.33 and/or at least 0.10 greater than the synthesis mixture Si/Al2 ratio. In another aspect, the aluminum and phosphorus sources are first combined to form a primary mixture that is aged. The silicon source and template can then be added to form the synthesis mixture. After inducing crystallization, in this aspect, both the synthesis mixture and crystallized sieve exhibit a Si/Al2 ratio less than 0.33 and/or the crystallized sieve has an average crystal size not more than 3.0 μm. The molecular sieve from both aspects can be used in a hydrocarbon (oxygenates-to-olefins) conversion process.
