Abstract

The aim of this study is to investigate the feasibility of using kaolin as a starting mate-rial in ceramic membrane support preparation using phase inversion/sintering techniqueat different kaolin content and non-solvent coagulant bath. The ceramic suspension wasprepared by mixing the kaolin, polyethersulfone (PESf) as binder, N-methyl-2-pyrrolidone(NMP) as solvent and Arlacel as dispersant using a magnetic stirrer; drying and sinteringprocess at temperature of 1200◦C. By varying the kaolin contents, different morphologiesof ceramic support were obtained due to the variations in viscosity of ceramic suspensions.Similarly, different non-solvent coagulant bath was found to affect the membrane supportstructure through liquid–liquid demixing process and at the same time affected membranesupport’s roughness, porosity, pore size distribution and strength. All ceramic supports pos-sessed high gas permeation with no separation capability, proven the suitability as ceramicmembrane support. The cost for the prepared ceramic membrane support in this work is aslow as $5.97, prepared at 54.0 g kaolin content and immersed into distilled water.
