Abstract
The invention relates to a method for extracting biochemical products obtained from a process of hydrothermal carbonization of biomass, which includes feeding an aqueous mixture of biomass from a preheating tube for the aqueous mixture of biomass to a vertical reactor with a predetermined level of floatation and an area for accumulation of steam and gases in the upper part thereof, wherein said method for extracting biochemical products is characterized in that it includes (a) heating the aqueous mixture of biomass to, or above, evaporation temperature in said vertical reactor and/or in a previous stage of preheating the aqueous mixture of biomass, increasing the generation of stream and/or gases at the predetermined flotation level of the vertical reactor, (b) extracting the steam and/or gases generated in the previous stage and accumulated in the upper part of the vertical reactor, and (c) cooling the gases and/or condensing the steam extracted in the previous stage at different levels of temperature and pressure. The invention likewise relates to the biochemical product obtainable from said method, as well as to a system for implementing said method.
