A method of producing biofuels, based on pyrolysis of biomass from macrophytes, includes: pre-treatment of biomass, including processes of drying and crushing the biomass, followed by injection of pre-treated biomass into a pyrolysis reactor; biomass pyrolysis in pyrolysis reactor; a first separation of products; a second separation of products; a third separation of products; burning or collecting gases, wherein the method produces at least four different types of products, including: biochar, pyroligneous extract, vegetable tar and synthesis gas; whereby, the biochar product is collected in the first product separation through the use of a cyclone, the pyroligneous extract product is collected in the second product separation through the use of a condenser, the vegetable tar product is collected in the third product separation through the use of a centrifuge, and the synthesis gas product is collected in the gas burning or collecting step.
