Abstract (en)
[origin: WO2014027059A1] Hydrothermal carbonization allows the production of charcoal from biomass. However, this biomass can at the beginning of the carbonization process contain constituents which are not suitable for carbonization. Apart from large contaminants such as broken glass, etc., these constituents are, in particular, sand and clay, with the clay not being able to be removed by simple filtration methods because of its fineness. The invention therefore provides for process water to be taken from the reaction space and subjected to purification in a sedimentation filter after the carbonization reaction has commenced and the clay is no longer held in the biomass. The process water is then sprayed back into the reaction space in order to keep the biomass/process water mixture in motion and avoid sedimentation of the clay at the bottom of the reaction space.
