Abstract: The invention provides an apparatus for thermolysis of waste plastics, particularly polyolefins. The apparatus includes a feeding system, an extruder, a main thermolysis reactor, a dual propeller/mixer housed within the reactor, and a discharging system. The height of the thermolysis reactor is at least 1.5 times bigger than the diameter. The apparatus is arranged such that the extruder follows the plastic feeding system, the thermolysis reactor follows the extruder, and the discharge system follows the thermolysis reactor. The invention also provides a method for using the apparatus for thermolysis of waste plastics. In this method, reaction feedstock, reaction residuals, and reaction products are removed continuously.

Abstract: The subject of the invention is apparatus and method for thermolysis of waste plastics especially polyolefins where reaction feedstock, reaction residuals and reaction products are removed continuously. Apparatus for thermolysis of waste plastics especially polyolefins includes plastic feeding system, pyrolysis reactor, discharge system according to the invention characterized in that after the plastic feeding system (1) the extruder (2) and pyrolysis reactor (3) which height is at least 1.5 time bigger than its diameter are situated. Pyrolysis reactor is equipped with dual high speed propeller (7). Method for thermolysis of plastic waste especially polyolefins thermolysis in the presence of inert gas according to the claim characterized in that plastic waste are continuously fed to the extruder where plasticized at 180° C. to the temperature of the reactor later are fed to the pyrolysis reactor where at 350° C.-450° C.
