Abstract
The invention relates to a method for hydrothermal carbonisation of biomass containing organic matter, the method comprising: —injecting the biomass, a heat transfer fluid and a reagent into a reactor (), —circulating a mixture consisting of the biomass, the heat transfer fluid and the reagent under specific pressure and temperature conditions for transforming the organic matter by hydrothermal carbonisation. The invention consists in: 1) determining the production rate of the emitted gas Tduring the hydrothermal carbonisation reaction; 2) comparing the determined production rate of the emitted gas Twith a predefined value for the set gas production rate T, and 3) adjusting at least one of the reaction control parameters chosen from among the temperature within the reactor (), the quantity of injected reactant, and the residence time in the reactor in order to adjust the production rate of the emitted gas T, such that the value of said production rate of the emitted gas Te tends to be equal to the value of the set gas production rate T. The invention is applicable to treatment of biomass containing organic matter.
