METHOD FOR PRODUCTION HYDROCARBON LIQUIDS WITH LOW CONTENT OF AROMATIC COMPOUNDS Russian patent published in 2015 - IPC C10G45/44 C10G65/08 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to the hydrogenisation of a low-sulphur raw material containing less than 15 mln^-1 of sulphur up to liquids with a very low content of sulphur and aromatic compounds containing less than 5 mln^-1 of sulphur and less than 100 mln^-1 of the aromatic compounds boiling within the range from 150 up to 400°C and having the boiling temperature range less than 80°C. The method includes a stage of the catalytic hydrogenation of the above raw material at a temperature from 80 up to 180°C and pressure from 60 up to 160 bar, consisting of two or three stages of hydrogenisation with a nickel-containing catalyst wherein each stage of hydrogenisation is carried out in a separate reactor, and a stage of hydrogenised products fractionating up to the liquids having certain boiling ranges.

EFFECT: method allows provision of the aromatic compounds content in the product of at least 100 parts per million without molecules cracking at low temperature and high pressure of hydrogenation.
