Provided is a method for manufacturing a polymer fiber adsorbent having an MOF uniformly distributed in the matrix thereof, the method comprising the steps of: spinning a spinning dope comprising a polymer matrix and a metal precursor of an MOF to prepare a polymer fiber adsorbent precursor comprising the metal precursor; and contacting the polymer fiber adsorbent precursor with an organic ligand of the MOF to form an MOF in the polymer fiber adsorbent precursor. A polymer fiber adsorbent manufacturing method provided by an aspect of the present invention offers a method capable of easy synthesis of an MOF which is sensitive to water, thereby obtaining a polymer fiber adsorbent excellent in terms of adsorption performance and long-term stability.

Structured metal-organic framework fiber adsorbent for capturing carbon dioxide and manufacturing method therefor

Methods for recovering methane gas from natural gas hydrates are provided. A representative method includes the step of adding a gas mixture containing air and carbon dioxide to a natural gas hydrate (NGH), the step of replacing the methane gas with the gas mixture, and the step of decomposition-replacement of methane hydrate.
