A phase-transfer crystallization pathway to synthesize ultrasmall silicoaluminophosphate for enhanced catalytic conversion of dimethylether-to-olefin

Abstract

We present a phase-transfer crystallization approach to the synthesis of ultrasmall (< 100 nm) SAPO-34 crystallites. The method is featured by porogen-free and tumbling crystallization in biphasic toluene-water media. The nanosized SAPO-34 catalyst has demonstrated prolonged catalysis lifetime (approximately 5 folds) and higher ethylene/propylene selectivity (by ca. 5%) for dimethylether-to-olefin conversion.
