FIELD: transport.
SUBSTANCE: invention may be used in chemical and cellulose industries. To produce biohydrogen and hydrocarbon biofuel, biomethanol is used made from black liquor representing aqueous solution containing residues of lignine, hemicellulose, and inorganic agents used in cellulose craft process. Biomethanol is purified and subjected to reforming to produce biohydrogen. Produced biohydrogen is purified and extracted. It is used as hydrogen source in producing flow of biohydrocarbons. Producing the flow of biohydrocarbons is executed using Fisher-Tropsh reaction for synthesis of synthesis gas from biomass, hydrodeoxygenation of biological triglycerides or fat acids or combination thereof. Producing the flow of biohydrocarbons one of operations selected from adjustment of relationship between hydrogen and carbon monoxide in synthesis gas, cracking/isomerisation of Fisher-Tropsh paraffins, hydrodeoxygenation of biological triglycerides or fat acids, hydroisomerisation of n-paraffins and reduction of catalysts. Obtained flow of biohydrocarbons is separated in fractions. Then, biofuel is extracted from one of said fractions. Biofuel production plant 20 comprises cellulose production plant 19 exploiting craft process, unit 12 for biomethanol extraction, unit 13 for biomethanol purification, reformer 7 and unit 8 for gas mix purification for purified biohydrogen production.
EFFECT: biofuel of one- hundred-percent-natural-origin.
