Preparation of titanosilicate ETS-10 and vanadosilicate AM-6 membranes

abstract

Pure titanosilicate (ETS-10) and vanadosilicate (AM-6) membranes were synthesized oil ceramic tubular Supports by seeded hydrothermai synthesis. The membranes have been characterized by X-ray diffraction (XR-D), scanning electron microscopy (SEM) and temperature programmed permeation (TPP) to 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 membranes).
