The conventional coating methods like dip-, spray- and film coating used to prepare zeolite membrane usually gives in-homogeneous membrane. Here we have used an rotary method to prepare zeolite membrane where a alumina tube was rotated at constant speed and at constant temperature in the zeolite reaction mixture. The zeolite membrane characterized by XRD and SEM was of Zeolite A type. The efficiency of the zeolite membrane was tested for its selectivity toward oxygen in 50% O2/N2 gas mixture. There was an increase of 2.8 wt% in the oxygen concentration. The surface area of the membrane was 22 cm(2).
