    Abstract

    Inorganic zeolite membrane NaA was known having high selectivity on liquid-liquid or gas-gas separation. Zeolite membrane NaA can be synthesized on α-alumina support with hydrothermal treatment. The solution of mole composition which used to make zeolite membrane NaA is NaOH:Al()H)3:SiO2:H2O, successively 2:1:2:120. XRD results showed that the membrane which made was zeolite NaA. Characterization result by using Scanning Electron Microscopy (SEM) was known that thickness of zeolite membrane NaA reaches 5 µm and nanocomposite zeolite NaA which formed on α-alumina support occurred homogeneously. Analysis of ethanol and methanol which produced in the product < 0.01%, and the flux permeate which produced is 0.3 and 0.5 kg/m2.h. The best operating condition in manufacturing of zeolite membrane NaA is the crystallization temperature of 110oC for 24 hours. Keywords: hydrothermal; membranes; NaA zeolite; α-alumina
