METHOD OF DEMERCANTIFICATION OF KEROSENE FRACTIONS Russian patent published in 2019 - IPC C10G45/02

Abstract RU 2691760 C1

FIELD: technological processes.

SUBSTANCE: invention relates to oil refining and can be used for cleaning kerosene fractions from mercaptans. Invention relates to a kerosene fractions demercuration process by contacting raw materials and hydrogen at high temperature and pressure in the presence of a catalyst. Note here that water is added to the kerosene fraction in amount of 0.01–0.03 wt.% before demercaptanisation. from kerosene fraction.

EFFECT: increased output of kerosene by 50 % while improving quality of its cleaning and lubricating capacity.
