•The trend in the number of waste tyres is increasing. One of the most promising ways of utilization is recycling for energy recovery. In this study, slow pyrolysis of waste tyres was conducted in a low tonnage industrial unit.•Pyrolytic oil was separated by a single condensation atmospheric distillation into 3 fractions, which were analyzed as a fuel component.•The obtained test results were compared to the fuel oil requirements (DSTU 4058-2001). That the pyrolytic oil fraction boiling >200°C matches the Ukrainian requirements for fuel oil types 40 and 100, while two others pyrolytic-oil fractions may be an interesting raw material for the production of aromatics. With the raising of environmental awareness, waste tyres recycling receives more attention. In this study, slow pyrolysis of waste tyres was conducted in a low tonnage industrial unit. Pyrolytic oil was separated by a single condensation atmospheric distillation into 3 fractions: gasoline fraction (boiling below 140°C), fraction boiling at the range of 140-200°C, and fraction boiling above 200°C. The obtained fractions were analyzed by chemical composition and potential use as a fuel component. The fraction boiling over 200°C, obtained with the highest yield of 78 wt.% meets all the requirements for the fuel oil pointed out in DSTU 4058-2001, PN-C-96024:2011, ISO 8217:2017, while lower boiling fractions may be an interesting raw material for the aromatics production (as styrene or limonene).
