9 PREPARATION OF PEROVSKITE TITANIA CERAMIC MEMBRANE BY SOL-GEL METHOD

摘要

Membranes play an important role in separation technology because membrane-based separation uses less energy and is more economically competitive than other conventional separation technologies, such as distillation, absorption, adsorption, solvent extraction, and cryogenics [1]. Among the various types of membranes, ceramic membranes are widely used due to their unique features, such as high temperature stability, high pressure resistance, good chemical stability, high mechanical resistance, long life, and good anti-fouling [2]. Presently, there are many researchers developing ceramic membranes to be used in oxygen separation. Applications that require oxygen separation include the oxidative coupling of methane (OCM) [3], partial oxidation of methane (POM) processes [4], and fuel cell systems [5].
