CO2 capture with liquid crystals

Master Student: Olcay Yuksel

Recently, research has started to a new class of solvents for CO2 absorption: liquid crystals. Liquid crystals are molecules with a structured liquid phase between the solid and isotropic (liquid) phase. The solubility of CO2 is higher in the isotropic phase than in the structured phase. Cooling down the mixture a few degrees is already sufficient to remove part of the absorbed CO2. Therefore, this process consumes probably less energy than required for the current amine process. In this project the solubility behaviour of CO2 in nematic liquid crystals is studied, in order to find the best liquid crystal for this process.
