Abstract:
A method for synthesizing small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves with high structural purity. The method includes first forming a slurry comprising monoisopropanolamine. Then, the slurry is aged to form an aged slurry. Finally, crystallization of silicoaluminophosphate molecular sieves comprising the SAPO-34 molecular sieves is induced from the aged slurry.
