Presentation Title Surface Modified ScSZ-MC Dual-phase Membrane for Pre-combustion CO2 Capture

On-Site Speaker (Planned) Shichen Sun
Abstract Scope In this presentation, we show a high-temperature ceramic-carbonate dual-phase (CCDP) membrane composed of a porous scandium stabilized zirconia (ScSZ) ceramic phase filled with a Li-Na molten carbonate (MC) phase for CO2 capture. To enhance the wettability of ScSZ phase to MC phase, surface modification methods such as wet-impregnation and atomic layer deposition (ALD) were adopted using Al2O3 as agent. Such surface-modified ScSZ-MC membranes show outstanding CO2 permeability and remarkable stability during long-term operation at 650oC. In addition, CO2 permeance was evaluated as a function of CO2 concentration. The H2S tolerance was examined during long-term stability test under a simulated syngas atmosphere containing trace amount of H2S. Moreover, as the CO2 permeability is considered to be dominated by the thickness of ScSZ ceramic phase, a bi-layer ScSZ membrane consisting of a surface-modified ScSZ thin layer and a thick porous supporting substrate was fabricated and studied.
