Torrefaction is an up to date technology of biomass thermal conversion that allows obtaining solid organic fuel with improved properties. The one of the main disadvantage of the torrefaction is necessity of volatile products utilization. Thermal conversion of volatiles info synthesis gas is the promising way to solve this problem. The results of experimental investigations of different kinds of torrefied biomass properties are presented. The quantity of gases obtained by high-temperature cracking of condensable and non-condensable volatiles formed during the torrefaction of wood, straw and peat at temperatures of 230°C, 250°C, 270°C are presented. It is shown that high-temperature conversion of the volatiles into synthesis gas is very effective method of utilization the torrefaction by-products.
