OIL ABSORBENT AND OIL ABSORBENT MANUFACTURING METHOD

摘要

The present invention relates to an oil adsorbent for recovering oil from water and a method for manufacturing an oil adsorbent. The oil adsorbent particle includes inorganic particles, and a polymer formed on surfaces of or between the inorganic particles, wherein the content rate of the inorganic particles is 50% by volume or more and 97% by volume or less relative to the inorganic particles and the polymer, and an area of the inorganic particles is 30% or more and 60% or less relative to a cross-section of the inorganic particles and the polymer. Also, the method of manufacturing the oil adsorbent particle includes mixing inorganic particles, a polymer, and a solvent to prepare a slurry solution, and spraying the slurry solution under an environment a temperature of is higher by at least 30°C than the boiling point of the solvent.
