Tiivistelmä
Hydrothermal carbonization is a thermochemical process, under which biomass material is converted into a lignite–like hydrochar. Hydrochar has better physical and chemical properties compared to the original feedstock and it has been utilized in various applications.
A new correlation between operational conditions (temperature, time and water : biomass ratio) and the hydrochar’s mass and energy yield for the case of defective coffee beans and corncobs has been developed. The analysis results of experimental data suggest that the behaviours of these biomass feedstocks differ from that of the reference material (woodchips), and thus new correlation equations should be proposed.
