Hydrophobic ceramics hollow fiber membrane with high efficiency and strength and preparation method thereof

摘要

The present invention relates to technologies of manufacturing a hydrophobic ceramic hollow fiber membrane capable of improving carbon dioxide absorption rate by adjusting a pore structure and forming a sponge structure, and applying the hydrophobic ceramic hollow fiber membrane in a gas-liquid contact separation membrane device for absorbing carbon dioxide. By controlling a pore structure of the hollow fiber membrane to form a sponge structure, resistance between gas and the hollow fiber membrane is minimized and carbon dioxide penetration can be improved. Also, dewetting properties are increased due to the sponge structure having the small average pore size so movement of gas and mass transfer become easy through pores. When the hollow fiber membrane is applied to a gas-liquid contact separation membrane device, carbon dioxide absorption rate can be improved.
