Abstract

Self-standing, planar dual-phase oxygen transport membranes consisting of 70 vol% (ZrO₂)_.89(Y₂O₃)_.01(Sc₂O₃)_.10 (10Sc1YSZ) and 30 vol% LaCr_.85Cu_.10Ni_.05O_3-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 1000 µm thick and 110 µm thick self-supported 10Sc1YSZ-LCCN (70–30 vol%) membranes from 700 °C to 950 °C using air as the feed gas and N₂ or CO₂ as the sweep gas. The 110 µm thick membrane, prepared by tape-casting and lamination processes, showed oxygen fluxes up to 1.02 mL_N cm⁻² min⁻¹ (950 °C, air/N₂). Both membranes demonstrated stable performances over long-term stability tests (250–300 h) performed at 850 °C using pure CO₂ as the sweep gas.
