HYDROPHOBIC FILTER FOR COLLECTING OIL PRODUCTS FROM SURFACE OF WATER AND METHOD OF ITS OBTAINING Russian patent published in 2017 - IPC C02F1/40 E02B15/04 C09K3/32 

FIELD: ecology.

SUBSTANCE: invention relates to the field of water purification from oil and oil hydrocarbon contamination. A hydrophobic filter for the collection of petroleum products from the surface of water, consisting of a cassette in which separate highly interconnected highly hydrophobic blocks are interconnected, made of high-temperature oxide materials with a density of 0.4-0.6 g/cm³, The outer surfaces of highly porous hydrophobic blocks and the inner surfaces of the pores of which are covered with a continuous carbon film. A method for producing a hydrophobic filter for collecting petroleum products from the water surface, including drying the highly porous hydrophobic blocks in an oven at a temperature of 300-400°C to a constant weight of the blocks, after which they are impregnated with the carbonaceous liquid until the outer surface of the highly porous hydrophobic blocks and the inner surface of the pores are completely covered, then pyrolysis is carried out in an inert gas atmosphere at a temperature of 700-900°C to complete graphitization of the surface coating of highly porous hydrophobic blocks.

EFFECT: increasing the efficiency of removing oil and oil products, simplifying the manufacturing process.
