Hydrothermal carbonization of peat

The influence of peat hydrothermal carbonization at 180 and 220°C for 8–10 h on the thermal characteristics of the resulting biochar was studied. It was found that hydrothermal carbonization reduced the yield of volatiles to about 50% and increased the calorific value (to 7200 or 7600 kcal/kg for th...

Description
Summary:The influence of peat hydrothermal carbonization at 180 and 220°C for 8–10 h on the thermal characteristics of the resulting biochar was studied. It was found that hydrothermal carbonization reduced the yield of volatiles to about 50% and increased the calorific value (to 7200 or 7600 kcal/kg for the lower or higher calorific value, respectively); that is, it afforded biochar whose characteristics approached those of fossil brown coal or black coal in terms of caloricity.
