Pure titanosilicate (ETS-10) and vanadosilicate (AM-6) membranes were synthesized on ceramic tubular supports by seeded hydrothermal synthesis. The membranes have been characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and temperature programmed permeated (TPP) measure the single gas permeances showing activated flow. At ambient temperature, the membranes exhibit promising propylene/propane separation factors (between 3.8-6.5 for ETS-10 membrane and about 2.3 for AM-6 membrane).
