Title:
HYDROPHOBIC ALUMINA HOLLOW FIBER MEMBRANE FOR CARBON DIOXIDE ABSORPTION AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2016/171426
Kind Code:
A1
Abstract:
The present invention relates to a technology for preparing a hydrophobic alumina hollow fiber membrane by modifying a surface of an alumina hollow fiber membrane, obtained by a phase transition method, with fluorinated alkyl silane (FAS). According to the present invention, by surface-modifying an alumina hollow fiber membrane through fluorinated alkyl silane (FAS) coating to allow the alumina hollow fiber membrane to exhibit hydrophobicity, a hydrophobic alumina hollow fiber membrane for carbon dioxide absorption can be provided that facilitates the migration of gas through pores of the membrane and the resultant mass transfer, thereby increasing the flow rate of an absorption liquid, thus remarkably increasing the absorption amount of carbon dioxide; and by applying a membrane module comprising the hydrophobic alumina hollow fiber membrane to a hollow membrane contactor, the absorption rate of carbon dioxide can be greatly improved.
