Abstract:
1. A method for preparing a hydrophobic adsorbent material having the ability to separate oil from water and/or binding oil, comprising adding with steady mixing 3.45-11.75 mass percent of an auxiliary material, which comprises 2.95-7.75 mass percent of a liquid adsorbent agent and 1.2-3.4 mass percent of liquid catalyst, to 29.3-86.2 mass percent of ground and dried CaO, then during additional steady mixing adding 18.25-55.75 mass percent of water and stabilizer, whereby a chemical reaction the adsorbent material is achieved, followed by dehydrating and allowing said material to cool and rest for 24-48 hours, wherein the composition of the adsorbent agent is: the composition of the catalyst is: in which the composition of the catalyst additive is: and the stabilizer is potassium silicate with a quantity of 0.01-0.002 mass % proportioned to the total mass of materials.
