The invention relates to a method for recovering hydrocarbons from plastic wastes, in particular polyolefin-rich waste, by means of purely thermolytic cracking without the use of catalysts, comprising melting the plastic waste in two heating devices (3) and (4), wherein a recycle stream derived from the cracking reactor (5) and purified in a separator system (8, 9) is admixed with the molten plastic waste from the heating device (3). The mixed plastic stream is further heated in the second heating device (4), and from there is guided into the cracking reactor (5), where the plastic materials are cracked, and by means of subsequent distillation are separated into diesel and low boilers. A special entry system allows the prior separation of water and acidic gases, and the saving of inert gas. The invention further relates to a system for carrying out the method.
A method for recovering hydrocarbons from reusable plastic materials comprising plastic-containing waste and organic liquids based on crude oil, from polyolefin-rich reusable plastic materials, by means of thermolytic cracking in a cracking reactor having a first heating device and a second heating device situated upstream therefrom, wherein the supplying of the plastic waste to the first heating device takes place via a feed system in which:
