The aim of this study was to determine the effect of time and temperature of torrefaction on selected parameters of torrefied woody biomass. The research material was willow and black locust biomass. First species representing the tree of soft wood and second is representative of hardwood trees. The selected species belong to a group of trees cultivated on energy purposes in so-called short rotation. The biomass samples were dried to a humidity of 10% and then was specified the calorific value, heat of combustion, specific density, ash content and volatiles matter. Characterized samples were subjected to torrefaction process in a special research reactor. In the study was planned the torrefaction temperature range 200–300 °C and the duration of the process in the range of 1–3 h which resulted in products of biomass torrefaction about the different degree of the carbonization, which were characterized by the same parameters as before biomass torrefaction.
