Microwave synthesis of mesoporous SAPO-34 with a hierarchical pore structure

SAPO-34 possessing a unique microporous–mesoporous hierarchical pore structure (Meso-SAPO-34(MW)) with a reduced particle size was prepared using a microwave heating method and applied as a catalyst for methanol-to-olefin (MTO) conversion reaction. All synthesized SAPO-34 catalysts were characterized via XRD, N2 adsorption isotherm and SEM. The Meso-SAPO-34(MW) demonstrated clearly improved MTO performance compared with those synthesized using the conventional SAPO-34 catalysts due to the catalyst deactivation alleviated by the introduced modifications in textural property.
