講　演： Pre-combustion CO2 Capture with Membrane Separation

講　師： Dr. Lie Meng
Research Institute of Innovative Technology for the Earth (RITE), Japan

講演内容： To realize a carbon-neutral, decarbonized society, efforts should be made to the capture of CO2 from sources such as the electricity production burning fossil fuels. Compared with traditional coal-fired power plants, the Integrated Gasification Combined Cycle (IGCC) offers improved thermodynamic efficiency and allows for capturing concentrated and pressurized CO2 before combustion. Membrane separation technology has the potential to be applied to carbon capture process in power plants as it is less energy-intensive and environmentally friendly, and it has been commercially used for gas puri?cation. This talk covers some recent advances in pre-combustion CO2 capture using CO2-selective membranes (including ceramic-carbonate dual-phase membranes and facilitated transport membranes) and hydrogen-selective membranes (e.g., zeolite membranes). The unique properties of ultra-selective and highly permeable membranes could offer a CO2 capture ratio >95% and CO2 purity >95%, which increases the competitiveness of membrane separation technology in pre-combustion carbon capture.
