FIELD: oil production particularly to produce petroleum solvents of sulfur-bearing oil having low aromatic hydrocarbon content.
SUBSTANCE: method involves obtaining fraction with initial boiling temperature of 140-195°C at one stage of oil refining operation; hydrofining of obtained fraction by passing thereof through two serially arranged reactors under temperature of not more than 300°C, wherein volumetric ratio between hydrogen containing gas and raw material is not less than 150 nm3/m3; stabilizing thereof under temperature of upper column part of not less than 150°C and temperature of bottom column part of not less than 180°C, wherein aluminum-nickel-molybdenum or nickel-molybdenum or aluminum-nickel-cobalt-molybdenum catalysts are used.
EFFECT: simplified technology, reduced power inputs and costs of petroleum solvent production.
