Patent ID: 7754642

Claim:
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: component volume percentage Palmitic acid 2.75-6.75% Stearic acid 0.75-3.75% Oleic acid 30-97.50% Linoleic acid 9.00-33.00% Linolenic acid 3.50-15% Erucidic acid <3% the composition of the catalyst is: component volume percentage Ethyl alcohol 45-97% Denaturant 0.1-0.50% Catalyst additive 3.00-54.5% in which the composition of the catalyst additive is: component volume percentage Benzine 33.75%-90% Benzol 10-30% Pyridine 3.75-11.25% Methanol 2.5-7.5% and the stabilizer is potassium silicate with a quantity of 0.01-0.002 mass % proportioned to the total mass of materials.
