FIELD: chemistry.
SUBSTANCE: invention concerns oil and fat industry. The method involves reacting oil with an adsorbent - a natural kaolinite-β-quarts mixture. Oil is passed through an adsorbent which is in form of granules with diametre of 3-5 mm and height of 5-7 mm at room temperature. The granules are obtained by moulding a natural mixture in the presence of sodium silicate solution with density of 1.32-1.43 g/cm3 in mass ratio of solid: liquid = 4:1-5:1 with subsequent cutting and drying to constant mass at 110-120 °C.
EFFECT: invention increases degree of purity of plant oil, excludes energy consuming operations and enables carrying out the process in continuous mode.
