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

摘要

The present invention relates to a technique for manufacturing a hydrophobic ceramic hollow fiber membrane capable of improving the carbon dioxide absorption rate by forming a sponge structure by controlling a pore structure, and applying the same to a gas-liquid contact membrane apparatus for absorbing carbon dioxide. According to various embodiments of the present invention, the pore structure of the hollow fiber membrane is adjusted to form a sponge structure, thereby minimizing the resistance of the gas and the hollow fiber membrane, and thereby improving the permeation amount of carbon dioxide. In addition, since the nonwettability due to the characteristic of the sponge structure having a small average pore size is increased, the movement of the gas through the pores and the mass transfer can be facilitated. Therefore, when the hollow fiber membrane is applied to a gas- And the like.
