あった。2. Description of the Related Art A conventional oil adsorbent used to adsorb and remove oil on the water surface caused by an oil leak accident is extremely thick on the surface of the water such as a visible light wavelength. thin oil film had a drawback that can not be absolutely absorption. or,
When the surfactant-containing oil cannot be adsorbed and the surfactant is mixed, it has a drawback that it absorbs water but hardly adsorbs oil.

た。[0003] Therefore, oil film can not be adsorbed by the oil adsorbent, neutralizing agent for pretend as was rather one Mim, i.e. sprinkle surfactant, oil dispersed in water, emulsified with water In addition to contamination, the surfactant itself has a BOC value and COD
The value was increased and the water was further polluted. Moreover, after spraying the surfactant, the oil containing the surfactant floats again. Since this oil cannot be adsorbed with the conventional oil adsorbent,
It was left as it was, causing a vicious circle that pollutes the environment.

る。The oil absorbent obtained by firing and carbonizing the squeezed grounds of coffee beans is tasteless and odorless, like many known activated carbons made from wood, charcoal, coconut shell charcoal, lignite, etc. The surface area is extremely large due to the fine pores. However, the oil absorbent of the present invention has unique properties that are not found in known activated carbons, that is, extremely water-repellent and oil-adsorptive properties.

材に吸収される。Since it is excellent in oil absorbency and water repellency which the conventional oil adsorbent does not have, it is possible to absorb the oil film which the conventional oil adsorbent could not adsorb. Further, it effectively absorbs oil mixed with a surfactant and oil in a water area mixed with a surfactant. Oil that flows out and floats on the water surface is also absorbed by this oil absorbing material.

The oil on the water surface can be absorbed quickly. Part 1
It is, to absorb the oil from the water surface with cloth scattered on the surface of the water the oil absorbent material directly. Since the oil absorbent has a specific gravity smaller than that of water, it absorbs oil while floating on the water surface and does not form an oil film. Further, since the oil absorbing material after absorbing the oil floats on the water surface as it is, it can be easily collected by a net or the like.

A bag of 23 cm in width and 2.2 cm in thickness is filled with an oil absorbent and a kapok, and floated as an oil mat on the water surface to absorb about 1.9 liters of oil. A plurality of the oil-absorbing bags can be connected and used, and the absorbent bag can be used as an oil fence by forming a long tubular shape.
As the water-repellent bag, water-repellent treated gauze, polypropylene woven cloth, nylon tubular bag, or the like can be used.
