Synthesis and properties of the silicoaluminophosphate molecular sieve SAPO-31
Abstract
The silicoaluminophosphate molecular sieve SAPO-31 has been synthesized and characterized by XRD, 27Al, 29Si, and 31P MASNMR, IR spectroscopy, electron microscopy, DTA-TGA, chemical analysis, and the catalytic conversion of methanol to light olefins. The results from XRD and NMR investigations show that hydration causes structural changes of the framework.
