چکیده انگلیسی
Self-standing, planar dual-phase oxygen transport membranes consisting of 70â¯vol% (ZrO2).89(Y2O3).01(Sc2O3).10 (10Sc1YSZ) and 30â¯vol% LaCr.85Cu.10Ni.05O3-δ (LCCN) were successfully developed and tested. The stability of the composite membrane was studied in simulated oxy-fuel power plant flue-gas conditions (CO2, SO2, H2O). The analyses of the exposed composites by X-ray diffraction (XRD), X-ray fluorescence (XRF), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and Raman spectroscopy revealed an excellent stability. Oxygen permeation fluxes were measured across 1000â¯Âµm thick and 110â¯Âµm thick self-supported 10Sc1YSZ-LCCN (70-30â¯vol%) membranes from 700â¯Â°C to 950â¯Â°C using air as the feed gas and N2 or CO2 as the sweep gas. The 110â¯Âµm thick membrane, prepared by tape-casting and lamination processes, showed oxygen fluxes up to 1.02â¯mLN cmâ2 minâ1 (950â¯Â°C, air/N2). Both membranes demonstrated stable performances over long-term stability tests (250-300â¯h) performed at 850â¯Â°C using pure CO2 as the sweep gas.
