PROBLEM TO BE SOLVED: To provide a method for producing a paper charcoal having greatly improved adsorption force for adsorbing oil selectively in a two-component state of water and oil, and to provide an oil adsorbing material including a paper charcoal obtained thereby.SOLUTION: An oil adsorbing material includes a paper charcoal obtained by a production method including: a step for obtaining a wet paper body from a raw material paper and water; a step for obtaining a molded wet paper body by molding the wet paper body; a step for obtaining a paper molded body by drying the molded wet paper body, or by forming a paper molded body without drying the molded wet paper body; and a step for obtaining a paper charcoal by carbonizing the paper molded body at 600-900°C in superheated steam. |
