Abstract: In the method of obtaining liquid biohydrocarbons from oils of natural origin, in the first step, the oil and/or waste oil is/are heated in the presence of a mixture of hydrogen and carbon monoxide in the presence of a catalyst in the form of a metal oxide selected from a group comprising CoO, NiO, MoO3, ZrO2, or a mixture of such metal oxides, on an oxide support selected from a group comprising SiO2, Al2O3, TiO2, whereupon the product of the first step is contacted with hydrogen gas or with a mixture of hydrogen and carbon monoxide in the presence of a metallic catalyst selected from a group comprising Pd, Pt, Co/Mo, Ni/Mo, Zr on an oxide support selected from a group comprising SiO2, Al2O3, TiO2, P2O5, ZrO2 or on a mixture of such oxides.
