METHOD FOR CLEARING LIQUID HYDROCARBONS OF HIGH MOLECULAR IMPURITIES Russian patent published in 2017 - IPC C10G31/11 C07C7/144 B01D61/14

Abstract RU 2622404 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for purifying a liquid hydrocarbon product containing not more than 3% by weight of polymeric impurities having a molecular weight of at least 8×10⁵ g/mol, wherein the liquid hydrocarbon product is contacted with a hydrophobic porous inklyudirovannoy ultrafiltration membrane comprising a substrate layer of a polymeric substrate, the hydrophobic polymer layer.

EFFECT: use of the proposed method increases the throughput while maintaining membrane selectivity.
