Synthesis of Zeolite Membranes from Coal Fly Ash

Abstract:

Article Preview

Zeolite membranes were successfully synthesized from coal fly ash by hydrothermal treatment onto 10-cm-long tubular porous supports. The membranes were characterized from XRD analysis, SEM observation and the pervaporation performance. Under the optimized conditions, LTA-type membrane from coal fly ash showed fairly efficient for the dehydration of organic liquids. The maximum selectivity reached more than 3000 with accompanying flux as high as 3.0 kg/(m2•h) for separation of 90 wt% EtOH aqueous solution at 75 °C.
