SORBENT MATERIAL AND METHOD OF ITS FABRICATION Russian patent published in 2009 - IPC B01J20/20 B01J20/26 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to sorbents of oil and oil products. Sorbent material consists of a layer of thermo-plastic polymer fibers bound between them and of a secured on fibers substance with hydrophobic properties; the substance corresponds to disperse carbon; particles of disperse carbon are of 50-1000 Angstrom size; share of carbon attached to fibers is from 1 to 25% of fibers weight. The method of fabrication of sorbent material consists in forming the layer out of thermo-plastic polymer fibers, in treating them with the substance possessing hydrophobic properties and in thermal processing of material to facilitate thermal binding of fibers; also as a substance with hydrophobic properties disperse carbon is used; thermal treatment is performed to attach carbon to the surface of fibers; after that not attached particles of carbon are removed.

EFFECT: invention facilitates increased sorbent property of material, rate of sorption and regeneration ratio and also increased floatability of material.
