Method for producing carbon film, carbon film and separator |
摘要 |
A method for producing a carbon membrane of the present invention is a production method where a carbon membrane obtained by subjecting a carbon-containing layer to thermal decomposition in an oxygen inert atmosphere while sending a gas mixture containing an oxidizing gas thereinto is thermally heated. The carbon membrane is subjected to a heating oxidation treatment with controlling the ratio of the flow rate of the gas mixture to the areas of the carbon membrane to 0.5 cm/min. or more to control (temperature ° C.)2×time (h)/10000, which is the relation between the temperature of the gas mixture and the flow time, to 9 to 32. This enables to obtain a carbon film which selectively separates alcohols having 2 or less carbon atoms from a liquid mixture of the alcohols having 2 or less carbon atoms and organic compounds having 5 to 9 carbon atoms.
