Effect of Temperature on the Hydrothermal Carbonization of Organic Fertilizers with the Production of Carbon Fuel

The effect of the temperature of hydrothermal carbonization of granulated organic fertilizer based on poultry manure on the yield and composition of the resulting biocoal was studied. It was found that an increase in the temperature from 180 to 210°C leads to a significant decrease in the moisture content of biocoal, but it significantly increased (from 39 to 53%) the fraction of carbon and the Lower heating value (LHV), Higher heating value (HHV) (from 15.69 to 22.36 and from 16.93 to 23.62 MJ/kg, respectively).
