Uncovering the transition between hydrothermal carbonization and liquefaction using differential scanning calorimetry

Matteo Pecchi et al.

Summary: In situ analysis of hydrothermal carbonization (HTC) and liquefaction (HTL) processes can be achieved using high-pressure differential scanning calorimetry (DSC). This study applies a newly developed DSC method to continuously assess the heat release profile of cellulose across the hydrothermal spectrum. The results reveal that both HTC and HTL are exothermic reactions, and a thermodynamic transition occurs at the transition from HTC to HTL. This novel DSC technique could reduce cost and time in evaluating potential feedstocks for HTC and HTL, expediting the commercialization of these thermochemical processes.
