Abstract:
Biogenic wastes and residues, especially those with high fractions of ash and contaminants (e.g. sewage sludge) are currently mainly thermally treated. Alternatively, materials low in impurities but with high water content are processed through fermentation. Hydrothermal carbonization (HTC) is a thermochemical process for the conversion of biogenic raw materials and residues to hydrophobic solids ("HTC - coal") with, in comparison to the starting materials, reduced weight and higher calorific value. Hydrothermal carbonization offers the possibility of using a single procedure by varying the process parameters to convert biogenic raw and residual materials with a very high carbon efficiency into valuable products such as solid fuel, substitute reducing agent for the processing of metal ores, soil conditioner, fertilizer etc. Different feedstock materials (wood chips, different nutshells, sewage sludge etc.) were tested to produce efficiently high quality, storable bio-chars for energetic use or as reducing agent as well as soil conditioner via hydrothermal carbonization.
