    • A method of manufacturing a carbon membrane for oxygen enrichment is provided to improve permeability and selectivity by increasing the contraction ratio of the membrane. A method of manufacturing a carbon membrane for oxygen enrichment comprises the steps of: primarily pyrolyzing a polyethylene naphthalate film in an inert gas atmosphere of a furnace in which a temperature of 300 to 500 deg.C is maintained for 0.5 to 1 hour; and secondly pyrolyzing the polyethylene naphthalate film in an inert gas atmosphere containing oxygen of a furnace in which a temperature of 700 to 800 deg.C is maintained for 1 to 2 hours. The polyethylene naphthalate film is prepared by using naphthalate that is an aromatic compound as raw material. The insert gas contains 0.5 to 1% of oxygen in the second pyrolysis process.
