An innovative method for preparation of Hydroxysodalite zeolite membrane

In this research, two new innovations have been made. The first innovation involves the synthesis of zeolite membranes from the source of kaolin. In the first step, the kaolin was calcined at 700C to the metakaolinite phase. As a second step, the zeolitisation experiments have been carried out under hydrothermal conditions. The metakaolinite obtained has been reacted with NaOH solutions in autoclaves at 100C. The second innovation to membrane synthesis was based on Self-supported zeolite membranes. Synthesis of Nano HS zeolite membrane from tubular extruded of kaolin was investigated. In the first step, kaolin has been calcined at 500-850 C to the metakaolinite phase. As a second step, the zeolitisation experiments have been carried out under hydrothermal conditions. The metakaolinite obtained has been reacted with NaOH solutions in autoclaves at 100C. X-ray diffraction (XRD) patterns of the membranes exhibited peak corresponding to the zeolite. The morphology of the support and membrane subjected to crystallization was characterized by Scanning electron microscopy (SEM). Separation performance of the HS membranes was evaluated using pervaporation (PV) of water–organic mixtures. The membranes showed high water selectivity in the water–organic mixtures.
