SAPO-34 zeolite with a butterfly patterned hierarchical pore system and high relative crystallinity was synthesized by a melting-assisted solvent-free route. Oxalic acid in the solid state was used as the etching agent through a facile thermal treatment of the parent SAPO-34. The resultant zeolite e...

Description
Summary:SAPO-34 zeolite with a butterfly patterned hierarchical pore system and high relative crystallinity was synthesized by a melting-assisted solvent-free route. Oxalic acid in the solid state was used as the etching agent through a facile thermal treatment of the parent SAPO-34. The resultant zeolite exhibited complete methanol conversion, high C 2 = -C 4 = selectivity (>91%) and a long lifetime in the MTO process. SAPO-34 zeolite with a butterfly patterned hierarchical pore system and high relative crystallinity was synthesized by a melting-assisted solvent-free route.
