Abstract

tIn this study, low cost ceramic supports were prepared from kaolin via phase inversion technique withtwo kaolin particle sizes, which are 0.04–0.6 um (denoted as type A) and 10–15 um (denoted as type B), atdifferent kaolin contents ranging from 14 to 39 wt.%, sintered at 1200◦C. The effect of kaolin particle sizesas well as kaolin contents on membrane structure, pore size distribution, porosity, mechanical strength,surface roughness and gas permeation of the support were investigated. The support was prepared usingkaolin type A induced asymmetric structure by combining macroporous voids and sponge-like structurein the support with pore size of 0.38 um and 1.05 um, respectively, and exhibited ideal porosity (27.7%),great mechanical strength (98.9 MPa) and excellent gas permeation. Preliminary study shows that thekaolin ceramic support in this work is potential to gas separation application at lower cost.
