Adsorptive permeation hollow fiber membrane, method of manufacturing the same, and gas adsorptive/desorptive separation system utilizing the same

摘要

Disclosed are an adsorptive permeation hollow fiber membrane formed by uniformly dispersing an adsorbent capable of selectively adsorbing only a specific gas in mixed gas components inside a porous hollow fiber membrane having a sponge structure capable of non-selectively permeating a mixed gas in a powder or crystalline powder form, a method of manufacturing the same, and a gas adsorptive/desorptive separation system utilizing the same.

主权项

1. A method of manufacturing an adsorptive hollow fiber membrane, comprising:
a step of mixing a polymer, a diluent, and an adsorbent to produce an adsorbent-dispersed dope solution; a step of spinning the adsorbent-dispersed dope solution to form a hollow fiber member having a generally annular shape with an exterior surface forming an outer boundary of the hollow fiber member and with an inner hollow passageway disposed within the hollow fiber member; and a step of cooling the hollow fiber member so as to form, by thermally induced phase separation (TIPS) method, the hollow fiber membrane having pores interconnected throughout the hollow fiber membrane, the pores being in fluid communication with the inner hollow passageway and having permeability to the entire mixed gas intended to be separated.
