<P>PROBLEM TO BE SOLVED: To provide a material which can be used as an oil absorbent material which exerts excellent resistances to water, detergents, chemicals and heat and an excellent recyclability and handleability after absorbing oil, shows an excellent oil absorption and water repellency capable of selectively absorbing oil in a mixed system of water and oil and does not release the absorbed oil into water upon being thrown into water, a water-repellent oil absorbent material and an oil separation process for an oil-water mixture using the same. <P>SOLUTION: The glassy carbon felt exerting an excellent oil absorption while retaining a water repellency, a chemical resistance and a heat resistance is manufactured by baking a felt essentially comprising a phenol resin fiber, especially a novolac phenol resin fiber which has been cured with formalin after melt spinning, in an inert gas atmosphere at 800-2,000°C. The water- repellent oil absorbent material is manufactured using this. The oil separation process uses this. <P>COPYRIGHT: (C)2004,JPO |
