FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining high-quality saturated base oil or a base oil component based on hydrocarbons. The method of obtaining a saturated hydrocarbon component for use as petrol, base oil, diesel components and/or solvent fractions involves oligomerisation of starting material which contains one or more components selected from a group comprising carboxylic acids having 4-38 carbon atoms, C4-C38 carboxylic acid esters and C1-C11 alcohols, C4-C38 carboxylic acid anhydrides and C4-C38 alcohols, in the presence of a cationic clay-based catalyst and deoxygenation. The starting material contains at least 50 wt % unsaturated and/or polyunsaturated compounds. The invention also relates to base oil obtained using the method given above, which is distinguished by that the base oil contains at least 90 wt % saturated hydrocarbons, 20-90 % mono-naphthenes, less than 3.0% polycyclic naphthenes, not more than 20 wt % linear parafins and at least 50 wt % saturated hydrocarbons have carbon number value interval not greater than 9 carbon atoms. The base oil is a biological product and has kinematic viscosity at 100°C ranging from 3 cS to 8 Cs.

EFFECT: obtaining saturated base oil which does not contain heteroatoms from biological starting material, which satisfies group III API requirements.
