摘要：A hydrophobic and oleophilic particular vermicular structure of expanded graphite, possessing the property of absorbing in a selective manner only large amounts of petroleum products from a water media is described. This expanded grahite is characterized by three main properties: (a) a specific density in the range of 0.003-0.1 g/ml; (b) a surface area in the range of 50-200 m.sup.2 g/ml; and (c) closed pores in the range of 3% to 20%. The particular structure of the expanded graphite can be used in the form of particulate, pillows, blankets, booms or as a filter medium. Preferred particles sizes of the expanded graphite are in the range of between 0.5 to 3 mm. The oil absorbed onto the expanded grahite can be released by pressure or recovered by solvent e xt r act ion.
