Abstract: Development of ceramic oxygen-electrolyte membrane reactor (COMR) represents an innovative exploration in pursuit of coupling solid-state electrochemical separation with high-temperature catalysis. Aiming to the developing of asymmetric tubular COMR by low-cost wet chemistry methods and integrating the air separation with catalytic partial oxidation of methane (POM) into syngas, this thesis has accomplished the following main technical or scientific breakthroughs: (i) inventing 5 types of low-cost methods for the fabrication of asymmetric tubular ceramic membrane; (ii) demonstrating extremely high oxygen permselectivity from air; (iii) solving the reductive thawing action to the membrane structure and the charcoaling effect on the catalyst of POM; and (iv) proposing three respective theoretical models, which supports the extrusion of ceramic-polymer blend, describes the effect of surface oxygen vacancy concentration to oxygen permeability, and offers an accurate insight for the unique POM mechanism brought about by associating oxygen electrolyte with the nickel catalyst.
