The aim of the work was, using a specially designed fast pyrolysis device, to determine optimum conditions for obtaining pyrolysis oil, to investigate its composition and properties, as well as to substantiate and experimentally confirm possible directions of the pyrolysis products usage. For obtaining of pyrolyses oil, the deciduous trees (ash (Fraxinus excelsior), grey alder (Alnus incana), and aspen (Populus tremula)) wood technological wastes had been used as raw material. Size of sawdust particles: 0.1-1.0 mm, moisture content - 6-8.5%. The water content in pyrolysis oil was determined by Karl Fischer titration; thermal capacity by calorimeter Oxygen Bomb Calorimeter-1341. In research of products' chemical composition, gas chromatography and analytical pyrolysis have been used.
