Title:
MODIFIED POROUS MEMBRANE MATERIAL AND PREPARATION METHOD, AND CARBON DIOXIDE LIQUID MEMBRANE SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/031675
Kind Code:
A1
Abstract:
The present invention relates to a membrane modification method for improving liquid membrane separation of carbon dioxide. The method is: grafting organic matter containing an amine group on a membrane material, then loading water into the pore channels of a porous membrane, making a supported liquid membrane used for a mixed gas separation experiment on carbon dioxide. The present invention, by means of a chemical grafting reaction to introduce an amine group, enables water to be, to a certain extent, alkaline when used as a membrane liquid, and, compared to other alkaline solutions used as membrane liquids, can avoid the loss of active alkaline matter, while also increasing carbon dioxide permeation flux.
