Hydrothermal Carbonization: Upgrading Waste Biomass to ...

Jan 11, 2021 Hydrothermal carbonization (HTC) is a thermochemical conversion process that uses heat to convert wet biomass feedstocks to hydrochar. HTC is performed in a reactor at temperatures ranging from 356 to 482 F, i.e., 180 to 250 C, under autogenous (automatically generated) pressure, with feedstock residence time ranging from 0.5 to 8 hours [1,2].
