Аннотация

The new architecture of IT thin oxygen membranes on a flexible support made of stainless steel grid is proposed. This membrane is designed to realize clean coal energy with combustion of pulverized low ranked solid fuels in oxygen enriched atmosphere using purified flue gases as a sweep gas. Multilayer membrane with thickness about 40 μm is consist of metal grid with deposited protected layer and filled by porous agglomerates of e-conducting perovskite, dense selective layer on the base of multilevel nanocermet δ-Bi2O3/Ag, protected porous layer and supported Pd/Pt-catalyst layer. Mechanochemical ceramic method is the main approach to designing of nanomaterials with interpenetrating and core-shell microstructures. Compatible combination of materials and operations is determined for creating oxygen membranes with operating temperature 500-550 °C. The best combination of materials successfully passed the degradation test at 500 °C for 500 hours.
