Composite hollow fiber membrane for production of high-quality biogas, membrane module comprising the same and manufacturing method thereof |
| abstract |
The present invention relates to a hollow fiber membrane having a bilayer structure comprising a porous inner layer of a first glassy polymeric material and a porous outer layer of a second glassy polymeric material; And a hollow composite membrane for carbon dioxide / methane separation wherein the surface of the hollow fiber membrane is coated with an organopolysiloxane copolymer having a repeating unit grafted with polyethylene glycol or polyethylene / propylene glycol. According to the present invention, since the permeability of carbon dioxide and the selectivity of carbon dioxide to methane are greatly improved at the same time, it is possible to selectively remove and remove carbon dioxide from a mixed gas of carbon dioxide and methane in the biogas solidification process, have. |
