Synthesis of NaA zeolite membrane on a ceramic hollow fiber

NaA zeolite membrane was successfully synthesized on a ceramic hollow fiber with an outer diameter of 400 μm, a thickness of 100 μm and an average pore radius of 0.1 μm. The as-synthesized membranes were characterized by XRD, SEM as well as gas permeation. A continuous NaA zeolite membrane formed after a three-stage synthesis. The membrane thickness was ∼5 μm. Gas permeation data indicated that a relatively high quality NaA zeolite membrane formed on the ceramic hollow fiber support.
