Claim:
1. A method for extracting biochemical products during a process of hydrothermal carbonization of biomass, comprising feeding an aqueous mixture of biomass from a preheating tube to a vertical reactor with a defined level of flotation and an area for the accumulation of steam and gases in its upper portion, wherein said method for extracting biochemical products comprises: (a) Heating the aqueous mixture of biomass up to or over an evaporation temperature of the biomass in the vertical reactor by means of a direct injection of at least one saturated overheated steam and/or of hot gases into the vertical reactor itself, below the defined level of flotation of the aqueous mixture of biomass to increase the generation of steam and/or gases at the set level of flotation of the vertical reactor and to release and form biochemical products; (b) Extracting the biochemical products alongside the steam and/or gases generated in the previous stage, which accumulated in the upper portion of the vertical reactor during a monomerization stage of the hydrothermal carbonization of biomass process; (c) Cooling the gases and/or condensing the steam extracted in the previous stage at differing temperature and pressure levels; and (d) Separating the biochemical products from the cooled gases and/or the condensed steam generated in step c).
