The article considers the processes of torrefaction and pyrolysis of biomass typical for Ukraine. The advantages of torrefied fuel and directions of its application are given. Technical problems that arise in industrial installations are separately considered (self-heating and self-ignition of the torrefied product, adsorption and condensation of liquid substances, the danger of self-ignition of torrefied gas). During the granulation of torrefied biomass, energy consumption increases 3 times compared to untreated biomass. Due to dry friction, abrasive wear of the matrix increases. The cost price of torrefied pellets is higher than that of fossil coal. Based on these considerations, it is assumed that torrefaction plants in Ukraine can be built with foreign equipment. The state of charcoal production in Ukraine has been analysed. A forecast has been made regarding further growth of its volumes. The production of biochar by the oxidative method for metallurgy and agriculture (biochar) is considered. Specific biochar rich in nutrients can be produced from granulated chicken manure and sewage sludge. A technological scheme for the continuous co-production of torrefied fuel and biochar has been developed. The use of oxidative pyrolysis reactors for creating cogeneration plants that produce both electrical and thermal energy from biomass has been considered.
