Hydrothermal carbonization of lignocellulosic biomass for energy production

Publication Details


Hydrothermal carbonization (HTC) of biomass is a thermochemical conversion technology that improves fuel characteristics of biomass without preliminary drying. The treatment process involves hydrolysis, dehydration, decarboxylation, polymerization, and aromatization mechanisms when raw feedstock is under a suspension with pressurized water at temperatures around 180–250 °C. In comparison with the feedstock, hydrochar is characterized by the increased carbon content and hydrophobic behavior, higher homogeneity, and better grindability. Besides the utilization for heat and power production, hydrochar can be found in other potential applications: for example, soil fertilizer, catalyst, energy storage, or absorbent. Understanding the effect of operational parameters on process mass and energy yields is essential for technology improvement and scaling-up of the applications.
