Hydrophobic Modification of Al2O3 Ceramic Membrane and Its Application to CO2 Capture
摘要
In order to further improve the CO2 capturing efficiency and fluxesFlux of the ceramic membraneCeramic membrane, the micron alumina ceramic membrane with a larger pore sizePore size is selected in this chapter. After the hydrophobicHydrophobic modificationModification, the structure and the mass transferMass transfer characteristics of the modified ceramic membrane are studied. The carbon capture performance is verified by experiments, and the crystal phase composition, the surface morphology, the contact angleContact angle, the pore sizePore size and the porosityPorosity of modified ceramic membranes are characterized in details. Furthermore, the operational factors affecting the CO2 capture efficiencyCapture efficiency of the hydrophobicHydrophobic Al2O3 ceramic membraneCeramic membrane are analyzed, and the stability of the modified ceramic membrane is discussed in details.
