Abstract

A novel and complete study of microwave-assisted synthesis parameters for ZSM-11 zeolite is provided. Several parameters were studied such as aging time, synthesis temperature, silica source, Si/Al molar ratio, template agent concentration and residence time of the initial synthesis mixture under microwave irradiation and conventional heating. Novel framework zeolite shifts from MEL to MFI, as well as the Ostwald ripening mechanism were observed. The microwave-assisted synthesis of ZSM-11without seeding was optimized after a complete study of the synthesis parameters.

Keywords: MEL, MFI, microwave, ostwald ripening, synthesis parameters, zeolites, ZSM-11.
