The subject of the invention is a hydrophobic, oil-adsorbent material separating oil from water as well as methods for production and application of said material, suitable for collecting and removing hydrocarbons and other contaminations of oil content from solid surface and water as well. During the method the adsorbent material is made from a chalk base raw material with an auxiliary material and during preparing the adsorbent material, ground and dried chalk (CaO) is used, which is characterized by that, during preparing the adsorbent material 29.3 - 86.2 mass percent, preferably 39.1 - 72.84 mass percent of ground and dried chalk (CaO) is applied as raw material, and during steady mixing 3.45 - 11.75 mass percent, preferably 4.12 - 9.21 mass percent of liquid adsorbent agent and liquid catalyst are added as auxiliary materials, the composition of which is 2.95 - 7.75 mass percent, preferably 4.15 - 5.85 mass percent of liquid adsorbent agent and 1.2 - 3.4 mass percent, preferably 1.34 - 1.76 mass percent of liquid catalyst, then during additional steady mixing 18.25 - 55.75 mass percent, preferably 26.55 - 48.45 mass percent of water and stabilizer are added to the well mixed and steadily blended material, then after the chemical reaction the ready adsorbent material is dehydrated, emptied and left to cool evenly and let it rest for 24-48 hours, and the composition of the adsorbent agent applied during the method is: 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 % ; furthermore the composition of the catalyst applied during the method is: Ethyl alcohol 45 - 97 % ; Denaturant 0.1 - 0.50 % ; Catalyst additive 3.00 - 54.5 % ; in which the composition of the catalyst additive is: Benzine 33.75 % - 90 % ; Benzol 10 - 30 % ; Pyridine 3.75 - 11.25 % ; Methanol 2.5 - 7.5 % ; and the stabilizer used during the method is potassium silicate with a quantity of 0.01- 0.002 mass % proportioned to the total mass of materials applied during the method. |
