FIELD: chemistry. n SUBSTANCE: invention relates to a method of producing fuel components from biological material. A method of producing fuel components from biological material includes the following steps: a) evaporating biological material to remove impurities and obtain pure biological material, wherein evaporation is carried out in two, three or more steaming steps, the first being carried out at temperature of 50-250°C and pressure of 5-100 mbar, b) hydrogenating the pure biological material in the presence of hydrogen gas and at least one catalyst to form a mixture of hydrocarbon compounds, c) separating the gaseous compounds from the obtained mixture of hydrocarbon compounds to obtain liquid hydrocarbon compounds, d) fractionating the obtained liquid hydrocarbon compounds to obtain fuel components, and e) recirculating part of the liquid hydrocarbon compounds obtained at the separation or fractionation step to the hydrogenation step. Also disclosed is a system for producing fuel components and fuel components obtained using the disclosed method. Also disclosed is use of fuel components and a composition containing fuel components. n EFFECT: method provides almost complete processing of raw material which includes a heavy fraction into valuable fuel components of good or high quality. n 30 cl, 3 dwg, 4 tbl, 3 ex |
