Effect of synthesis parameters on performance of Faujasite Membranes abstract
Effects of synthesis parameters on the membrane structure and performance have been investigated for Faujasite zeolite membranes. X-ray diffraction (XRD) patterns of the membranes exhibited peaks corresponding to the support and the zeolite. The crystal species were haracterized by XRD and morphology of the supports subjected to crystallization was characterized by Scanning electron microscopy (SEM). Separation performance of Faujasite (NaX, NaY) zeolite membranes was studied for water-unsymmetrical dimethylhydrazine (UDMH) mixtures using pervaporation (PV). The membranes showed good selectivity towards water in the water-UDMH mixtures. Water permeates faster because of its preferential adsorption into the nano-pores of the hydrophilic zeolite membrane. In PV of water- UDMH mixtures, the membrane exhibits a hydrophilic behavior, with a high selectivity towards water and a good flux. The best membranes had a water flux of 4.00 and 2.92 kg/m2.h at 27 oC for NaY and NaX respectively. The best PV selectivity was obtained to be 90 and 40 for NaY and NaX respectively.
