Problems solved by technology

(4) Distillation step, where the resulting oil mixture is usable as furnace oil, but not pure enough for engines
Therefore, the heat transfer coefficient is not ideal
[0019] It is also understandable that the viability of methods for extracting diesel from plastics is limited given that the method itself produces large quantities of contaminated waste solvents

Embodiment Construction

[0101] refer to figure 1 , provides a system 10 for converting plastics into hydrocarbon fuels such as diesel, gasoline and liquefied petroleum gas (LPG). The classification of hydrocarbon fuels is mainly determined by the chain length range of the hydrocarbons in the fuel mixture, for example diesel hydrocarbons usually range from C10-C25, gasoline hydrocarbons are C4-C12 and liquefied petroleum gas (LPG) usually contains propane ( C 3 h 8 ) and butane (C 4 h 10 )mixture.

[0102] System 10 includes plastic feedstock 500 supplied to kiln 100 . Plastic feedstock 500 may be any plastic material formed from long-chain organic polymers, such as waste plastic material (such as plastic packaging or car tires). Prior to introduction into the kiln 100, the plastic feedstock 500 may be pretreated, such as crushed or shredded to improve handling and surface area of ​​the plastic feedstock, or dried to minimize the amount of water introduced into the system. Plastic raw material...

Abstract

Disclosed herein is a kiln (100) for use in the production of hydrocarbon fuels from plastics. The kiln (100) comprises a scrubber (200) in fluid communication with a reaction chamber (130), the scrubber (200) being configured to condense hydrocarbons in the reaction chamber gas product stream (501) above a predetermined upper hydrocarbon range for returning to the reaction chamber (130) for further heating in the absence of oxygen. Also disclosed herein is a method of converting waste plastics to a commercially-useful form by way of diesel or the like. The method comprises treating a crude fuel produced from plastics in a pyrolytic process with a first extraction step comprising counterflow liquid-liquid extraction, and a second extraction step comprising counterflow extraction of solvents from the first extraction step.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to the following Australian provisional patent applications: AU2015904828, filed 24 November 2015, entitled "Kilns for use in the production of hydrocarbon fuels from plastics"; AU2016901654, filed 5 May 2016 , entitled "Plastic Derived Fuels and Methods of Making the Same," and AU2016902869, filed July 21, 2016, entitled "Plastic Derived Fuels and Methods of Making the Same II," the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure generally relates to the production of hydrocarbon fuels from waste plastic materials. Background technique [0004] Plastics are materials typically formed from long-chain organic polymers. Due to the relatively low cost of production and the ease of manufacture, plastic materials are used throughout the world in a variety of products, including a large number of single-use produ...
