Biomass energy is an important area of renewable energy. However, the efficient use of raw biomass for energy purposes does not always have the desired effect, so there is a need for biomass processing. One of the ways to improve the fuel characteristics of biomass is its torrefaction. Torrefaction allows to obtain fuel with a high energy density, which in energy terms will be close to coal. This retains most of the benefits of burning biomass over fossil fuels. There is no universal way to determine the optimal modes of heat treatment of biomass, so the study of effective methods and parameters of torrefaction for individual crops continues today. This paper investigates the influence of different regimes of heat treatment of Miscanthus Giganteus biomass on the fuel characteristics of the torrefied product and the changes that occur in the biomass. The research was conducted at the research facility for torrefaction in the educational and scientific laboratory “DAK GPS” of the higher educational institution “Podillia State University”. The method of heat treatment in a static layer was used, which eliminates the influence of side factors on the process of torrefaction. Regularities between the initial parameters of raw biomass, selected modes of torrefaction and the characteristics of the final product are established. The results of these studies will allow to develop a system of recommendations for optimally balanced and energy efficient production of torrefied product from biomass of Miscanthus Giganteus. The research has established that the optimal temperature for torrefaction of Miscanthus Giganteus biomass can be considered 250–300 °C.
