FIELD: chemistry.

SUBSTANCE: invention relates to two versions of a method for selective production of hydrocarbons which are suitable for making diesel fuel, one of which is characterised by that it includes a step where a decarboxylation/decarbonylation reaction is carried out by reacting material from renewable sources containing C₈-C₂₄ fatty acids, esters of C₈-C₂₄ fatty acids, triglycerides of C₈-C₂₄ fatty acids or metal salts of C₈-C₂₄ fatty acids or their combination, and a solvent or mixture of solvents if desired, with a heterogeneous catalyst which, if necessary, is pre-treated with hydrogen at 100-500 °C before brought into contact with the raw material, which contains 0.5-20 % one or more group VIII metals selected from platinum, palladium, iridium, ruthenium and rhodium or 2-55% nickel on a carrier selected from oxides, mesoporous substances, carbonaceous carriers and catalyst structural carriers, at temperature of 200-400°C and pressure between 0.1 and 15 MPa, to obtain a mixture of hydrocarbons as the product.

EFFECT: use of the method enables to obtain hydrocarbons which are suitable for making diesel fuel from renewable sources, which reduces hydrogen consumption.
