Effect of Temperature on the Torrefaction of Peat
The effect of temperature on the torrefaction (mild pyrolysis) of peat was studied. The process was carried out under anaerobic conditions at atmospheric pressure and a temperature of 230–300°C. It was established that an increase in the temperature from 230 to 270°C leads to a certain decrease in the yield of biocoal and an increase in the gas formation. However, in this case, the fraction of carbon in the material increases by 10%. As a result, the calorific value of solid fuel increases to 25–26 MJ/kg. The process is characterized by a high carbon efficiency (about 90%)
