<p>The inventive method includes thermal liquefaction of wastes in an organic solvent at a temperature above 270°C and a pressure up to 6 MPa. The liquid fraction is separated from the undissolved product. The liquid fraction is distilled into the fraction with the boiling temperature below 220°C and the fraction with the boiling temperature above 220°C. Alkyl benzene or the gasoline fraction with a boiling temperature below 220°C is used as an organic solvent at the start-up of the process. Thermal liquefaction of a batch of wastes is carried out in an organic solvent at a temperature from 280°C to 435°C and a pressure at least 2.9 MPa, the organic solvent-waste weight ratio being more than 1.0. The liquid fraction with the boiling temperature below 220°C is subjected to catalytic reforming. A part of the liquid fraction, as subjected to catalytic reforming, with the boiling temperature below 220°C is used as the target product, and the remaining part of the liquid fraction, as subjected to catalytic reforming, with the boiling temperature below 220°C is used as a solvent and returned for the</p> |
