Method for recycling organic polymeric wastes

摘要

The invention relates to a chemical recycling of organic industrial and polymeric wastes. The inventive method consists in thermally fluidifying wastes at a temperature higher than 270 DEG C and at a high pressure at least in one solvent i.e. alkyl benzene. After thermal fluidifying, a liquid fraction is separated and distilled. For the thermal fluidifying, a high pressure not lower than 6.1 MPa is used. After distillation, the liquid fraction with a boiling point not lower than 210 DEG C is introduced into the solvent as an additional component. The mass ratio between the additional component and the solvent is not less than 1:1.
