Physicochemical Properties of Biocoal Obtained by the Mild Pyrolysis of Peat

The effect of mild pyrolysis methods (hydrothermal carbonization and torrefaction) on the physicochemical properties of biocoal was studied. It was established that biocoal obtained by hydrothermal carbonization has a large specific surface area and exerts an exothermic effect upon decomposition; as compared with the samples obtained by torrefaction, it has a more dispersed structure and lower ash content.
