PROCEDURE FOR PRODUCTION OF HYDROCARBONS FRACTIONS Russian patent published in 2011 - IPC C10G47/12 C10G47/16 

FIELD: oil and gas production.

SUBSTANCE: invention refers to procedure of production of hydrocarbon fractions including stage of catalytic hydro-cracking of source hydrocarbon compounds containing poly-cyclic aromatic hydrocarbons and where ratio of carbon atoms forming aromatic cycle is as high, as mole 35 %. Also, the said ratio corresponds to a share of carbon atoms forming aromatic cycles in total amount of carbon atoms in oil at presence of hydrogen with purpose of conversion of not less, than 40 % of fractions with boiling temperature as high, as 215°C into fractions, boiling temperature of which is less, than 215°C. Thus, there is produced oil subjected to hydro-cracking containing 30 vol. % or more of mono-cycle aromatic hydrocarbons.

EFFECT: production of light hydrocarbons and simultaneously efficient and selective production of mono-cyclic aromatic hydrocarbon corresponding to alkyl-benzenes of high value.
