摘要:
The present invention provides a method of regenerating an oil adsorbent, wherein an oil adsorbent even if containing a large amount of oil can be regenerated without taking it out from the facility. The method of regenerating an oil adsorbent comprises washing a carbonaceous oil adsorbent made from calcined coke, with oil adsorbed thereon, with warm water of 40° C. or higher or gas-bubbled warm water of 40° C. or higher.
