Abstract

Zeolite NaA membranes were obtained by using a continuous recirculating flow, 0.25-5 ml min-1 of synthesis solution along the inner side of asymmetric porous alumina tubular supports. The membranes of 5 μm in thickness showed a N2 permeance of 5 × 10-7-1 × 10-6 m-2 s-1 Pa-1. The procedure developed in this work provides control of the synthesis and crystallization conditions at any position on the tubular support, thus implying scale-up.
