摘要： The invention provides a method for breaking down long chained hydrocarbons from plastic-containing waste and organic liquids based on crude oil, comprising providing material containing long-chained hydrocarbons; heating a specific volume of the material containing long-chained hydrocarbons to a cracking temperature, at which cracking temperature the chains of hydrocarbons in the material start cracking into shorter chains; and for the specific volume having a temperature above the cracking temperature, exposing the specific volume to heat which is less than or equal to 50° C. above the temperature of the specific volume. The invention also provides an apparatus for carrying out the invention.

摘要： 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.
