Benefits of technology

The present invention aims to use a limited amount of petroleum products to reduce human-produced CO2 emissions. The invention also aims to provide energy for the method through re-use, making the method self-sufficient in terms of energy.

Problems solved by technology

These microparticles are taken up by fish and other organisms living in the ocean severely affecting their health.
Thus, it would be beneficial for the environment if plastic materials were to be recycled and the release of additional CO2 into the atmosphere would be limited by lowering the extraction of petroleum products.

first embodiment

[0282]FIG. 1 illustrates the invention comprising a primary cracking reactor (20) capable of transforming at least one plastic material into a first hydrocarbon fluid being a gas by primary cracking. The first hydrocarbon fluid is directed via the fluid connection to a catalytic hydrogenation reactor (40) capable of transforming the first hydrocarbon fluid to a second hydrocarbon fluid by catalytic hydrogenation. The second hydrocarbon fluid is directed via the fluid connection to a fractional separator (80) for fractional separation of the second hydrocarbon fluid into three products being a light fraction (81), a medium fraction (82) and a heavy fraction (83).

second embodiment

[0283]FIG. 2 illustrates the invention comprising a primary cracking reactor (20) followed by a catalytic hydrogenation reactor (40). The waste plastic is fed to the primary cracking reactor (20) producing a first hydrocarbon fluid being a gas. The first hydrocarbon fluid is then exposed to catalytic hydrogenation (40) forming a second hydrocarbon fluid. In an alternative embodiment, a filter such as illustrated in FIG. 8 (27) at an outlet of the primary cracking reactor (20) is present (not shown in FIG. 2). After catalytic hydrogenation (40), the hydrocarbon fluid is exposed to condensation in a condenser (60) and separation in a post-condensation separator (65) resulting in a first non-condensable gas and a first hydrocarbon liquid as the second hydrocarbon fluid to enter the fractional separator. The first hydrocarbon liquid is fed to a fractional separator (80) and being separated into a light fraction (81), a medium fraction (82) and a heavy fraction (83).

third embodiment

[0287]FIG. 3 illustrates the invention, where waste plastic is fed into a primary cracking reactor (20). The hydrocarbon fluid exiting the primary cracking reactor (20), being a gas, is then exposed to a catalytic cracking in a pre-hydrogenation catalytic cracking reactor (30) before the first hydrocarbon fluid is catalytic hydrogenated in a catalytic hydrogenation reactor (40). The resulting hydrocarbon fluid is then condensed in a condenser (60) and separated in a post-condensation separator (65) a first non-condensable hydrocarbon gas and a first hydrocarbon liquid. The first hydrocarbon liquid is fed to a fractional separator (80) for fractional separation of the second hydrocarbon fluid into three products being a light fraction (81), a medium fraction (82) and a heavy fraction (83). The first non-condensable hydrocarbon gas is re-circulated to a gas burner (19) heating up the primary cracking reactor (20).

Abstract

The present invention relates to a method for producing fuel and additional hydrocarbons from waste plastic comprising the steps of providing at least one plastic material; exposing said at least one plastic material to a primary cracking to obtain a first hydrocarbon fluid; said first hydrocarbon fluid being a gas; exposing said first hydrocarbon gas to a catalytic hydrogenation to obtain a second hydrocarbon fluid; fractional separation of said second hydrocarbon fluid to obtain at least one final product. The present invention further relates to a waste recycling system for recycling waste plastic into fluid hydrocarbon compounds.

Description

FIELD OF THE INVENTION[0001]This disclosure relates to the recycling of waste plastic and its transformation into hydrocarbon fuels and other hydrocarbon compounds by means of primary cracking and gas-phase catalytic hydrogenation, before fractional separation.BACKGROUND OF THE INVENTION[0002]Huge amounts of plastics end up in nature every year. The environmental consequences hereof have recently been realised. Not only does it destroy the esthetics of nature but it is realised that huge amount of microparticles are formed in particular in the oceans. These microparticles are taken up by fish and other organisms living in the ocean severely affecting their health.[0003]At the same time, it is well known that the release of CO2 to the atmosphere could beneficially be reduced as CO2 is acknowledged to be a major factor in global heating. Advantageously, the extraction of petroleum products could be reduced in order to lower the CO2 outlet. One way of limiting this extraction could be ...
