Abstract
An oil adsorbent is manufactured by including performing heat treatment on a non-woven fabric for low-temperature carbonization, and has the effect of adsorbing and evaporating oil having various carbon numbers ranging from a low boiling point to a high boiling point to remove the oil, has photothermal conversion efficiency, high evaporation efficiency of oil by sunlight, and a high adsorption amount and high adsorption rate, thereby making the adsorption-evaporation cycle fast and efficiently performing the adsorption-evaporation, and has an environmentally friendly effect that does not cause any environmental problems even if the oil adsorbent is put into a river, a sea, or the like and then lost.
