Today, the limitations of traditional energy sources based on oil, natural gas and coal are becoming obvious. Therefore, the search for new sources of energy is a pressing issue both for modern Russia and for the whole world. The alternative sources of energy, based on the use of bioenergy of biomass, begin to play a significant and growing role in the world energy industry. The article presents the curves of changes in the mass yield of products obtained during the pyrolysis of biomass, thermally pre-treated in the temperature range of 180-270 °C without access of oxygen. It has been experimentally proved that pre-heat treatment reduced the total liquid yield in the pyrolysis process: with an increase in the processing temperature, the mass yield of the liquid decreased, but the mass yield of charcoal and gas changed slightly. At the same time, it was found that the temperature affected the yield of the elemental composition of biomass: as the temperature increased, the content of elemental carbon in the biomass increased, while the content of hydrogen and oxygen decreased. It is concluded that the preliminary heat treatment of biomass can improve the quality of the final liquid biofuel by reducing the water content in it and by increasing the heat of combustion. It is also found that pressure reduction during the pyrolysis process increased the yield of the liquid fraction of decomposition products.
