Effect of Temperature on the Hydrothermal Carbonization of Peat

Аннотация

The effect of the temperature of hydrothermal carbonization of peat on the yield and composition of the resulting biocoal was studied. It was found that an increase in the temperature from 160 to 230°C leads to a significant decrease in the moisture and ash contents of biocoal, but it significantly increased (from 52 to 68%) the fraction of carbon and the net and gross calorific values (from 20.2 to 26.77 and from 21.5 to 28.03 MJ/kg, respectively).
