CRYSTALLINE POROUS SILICOALUMINOPHOSPHATES AND METAL-SUBSTITUTED SILICOALUMINOPHOSPHATES WITH A HIERARCHICAL PORE STRUCTURE COMPRISING MICROPORES AND MESOPORES, METHODS FOR MAKING THE SAME, AND METHODS FOR CONVERTING OXYGENATES TO OLEFINS VIA REACTIONS CATALYZED BY THE SAME

摘要

Crystalline porous silicoaluminophosphates and metal-substituted silicoaluminophosphates with a hierarchical pore structure comprising micropores and mesopores, methods for making the same, and methods for converting an oxygenate to an olefin via reactions catalyzed by the same are provided. In an embodiment, crystalline porous silicoaluminophosphates with a hierarchical pore structure have mesopores with a minimum dimension of about 25 Å to about 475 Å that constitute at least about 7% of the total pore volume.
