摘要: Abstract Capture and storage of CO2 (CCS) from fossil-fuel power plants is vital in order to counteract a pending anthropogenic global warming. High temperature oxygen transport perovskite membranes can fulfill an important role the separation air needed oxy-fuel technologies for CCS. In this study we present development, performance stability gastight, macrovoid-free sulfur-free Ba0.5Sr0.5Co0.8Fe0.2O3 − δ (BSCF) mixed conductor capillary prepared by phase-inversion spinning sintering. A polymer was chosen obtain phase-pure BSCF crystal phase. Special attention given solution ceramic suspension avoid macrovoids achieve gastight membranes. The capillaries showed average 4-point bending strength 64 ± 8 MPa maximum flux ∼5.3 Nml/(cm2 min) at 950 °C argon sweep flow rate 125 Nml/min. comparison sulfur-containing with similar dimensions revealed profound impact sulfur contamination on both activation energy overall mechanism. Both long-term permeation different temperatures post-operation analysis were performed discussed.
