Hydrothermal carbonization (HTC) is a relatively recent technology
that offers the benefits of converting the biomass into
homogenous lignite-like material. In this process, biomass in a
mixture with water is kept during a certain period of time in a
closed vessel in the temperature range of 180–250 ◦C (pressure
Solids (hydrochar), aqueous solution, and some amount of gases
(about 10% by mass of feedstock) are generated during the HTC
process. Hydrochar presents the main product of the process. In
comparison with the feedstock, hydrochar is charactarized by the
increased carbon content , higher homogeneity, better
grindability, and hydrophobic behavior . These improved
product characteristics together with the independence from feedstock moisture make the HTC process a promising technology for enhancing biomass fuel properties. Besides the utilization for heat and power production, hydrochar may find other potential applications: for example, soil fertilizer, catalyst, energy storage, or
absorbent .
