Abstract: The paper describes the investigations of the physicochemical properties of biocoal, a solid fuel obtained following the carbonization of rice starch. The production of biocoal (carbonization) was completed at the temperature of 600 °C in the nitrogen atmosphere. As a result of the carbonization, amorphous carbon with high monodispersity was obtained, devoided of oxygen elements and was a very well developed BET specific surface—360 m 2 g −1 . The investigations of the technical parameters have confirmed a very high concentration of energy. The calorific value of 53.21 MJ kg −1 and the combustion heat of 54.92 MJ kg −1 are significantly higher than those of starch before carbonization (18.72 MJ kg −1 and 19.43 MJ kg −1 , respectively) and these values for typical biomass fuels. These values are also greater than those of hard coal. Other advantageous features of the obtained fuel are low ash (0.84%) and moisture content. These features predispose this fuel for the application as an alternative to conventional fuels.
