FIELD: chemistry.
SUBSTANCE: invention relates to a method for selective production of fraction of alkanes, suitable for petrol and diesel fuel. Method is characterised by that it includes a step, for simultaneous decarbonylation/decarboxylation and direct hydrodeoxygenation of raw material, originating from renewable sources and containing triglycerides of fatty acids and/or derivatives thereof, at temperature of 350-450 °C and pressure from 10 to 50 atm in presence of a heterogeneous catalyst, which is reduced with hydrogen at temperature of 400-500 °C for 11-12 hours prior to bringing into contact with raw material, wherein heterogeneous catalyst based on gamma-aluminium oxide, prepared using platinum acetate blue is used, containing 0.1 to 1 wt% of platinum.
EFFECT: method provides high output of end products and longer service life of catalyst.
