No.64 Preparation and Permeation Properties of Zeolite Membranes Prepared from Coal Fly Ash

Abstract

LTA, FAU and MFI zeolite membranes were successfully synthesized form coal fly ash by hydrothermal treatment onto 10-cm-long tubular porous α-alumina supports. The membranes were characterized from XRD analysis, SEM observation and the pervaporation performance. Under the optimized conditions, zeolite membranes from coal fly ash showed fairly efficient for the pervaporation separation of organic liquids.
