Technical Field

[0001] It is an invention of a system that can simultaneously achieve the three major recycling of industrial waste (waste tires, plastics), and it is an invention derived from these inventions towards SDGs (realization of a sustainable society). We aim to construct business models such as national policies for the sake of the world and people, biomass future industrial city concept, preventive care special zone, eco-town special zone, etc.

Background Art

[0002] As a background art patent, the manufacturing method of conductive carbonized biomass has already obtained a patent in 2008. At that time, among the three major recycling that were not regarded as problems, it was a patent for the manufacturing method of new material biomass carbon.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Forestry waste (bamboo, wood, etc.) and industrial waste (waste tire rubber, plastics) have long lacked new technologies for simultaneous treatment of the three major recycling. Although discharge operators, countries, and scientists around the world have been seriously researching, no new technology has been discovered yet.

Means for Solving the Problems

[0005] Example 1 for solving the above problems is Waste tire rubber within the range of 100°C to 400°C Used salad oil using heat treatment to perform oilification, The used salad oil extracting the Metals and rubber carbides that has not melted in the rubber carbide performing gas recovery on the above Oxygen-free state in a high-temperature system of 400°C to 1000°C in an argon atmosphere, and the It is a rubber carbide.

[0006] To solve the above problem, Example 2 is a process of heat-treating forestry waste (bamboo, wood) using an oily solution (waste salad oil) in the range of 100°C to 400°C. Carbonized biomass was obtained through a process of extracting undissolved material (hereinafter referred to as carbonized biomass, etc.) from the oil, and a process of simultaneously recovering gas from the carbonized biomass, etc. at a high temperature of 400°C to 1000°C in an oxygen-free environment.

[0007] The embodiment 4 that solves the above problem is A process of heating waste tire rubber with waste salad oil in the range of 100°C to 400°C to turn it into oil, a process of extracting metals and rubber carbides that have not dissolved in the waste salad oil, and the rubber carbides of Oxygen-free state The gas was recovered in a high-temperature system at 400°C to 1000°C in an argon atmosphere. rubber carbide of Under an argon atmosphere without oxygen Then it is further treated at a graphite structure formation temperature of 1800°C or higher. obtained conductive It is a rubber carbide.

[0008] Example 4, which solves the above problem, obtained conductive carbonized biomass (new material carbon) by further processing the carbonized biomass in an argon atmosphere (oxygen-free state) at a graphite structure formation temperature of 1800°C or higher.

[0009] Industrial waste (waste tire rubber, plastics) was heat-treated with an oily solution (waste salad oil) in the range of 100°C to 400°C. The oil, which was in a semi-molten state, was then analyzed by gas chromatography to identify the components that vaporize and burn at 280°C. (Figure 1)

[0010] Conductive carbonized biomass and conductive carbonized rubber were obtained by subjecting the aforementioned forestry waste (bamboo, wood) and industrial waste (waste tires, waste plastics) to a graphite structure formation treatment temperature of 1800°C or higher. This completes the SDGs (Sustainable Development Goals) simultaneous recycling system (chemical, material, and thermal) for forestry waste (bamboo, wood) and industrial waste (waste tire rubber, plastics).

[0011] This invention is a derivative patent, applying a proprietary patent obtained in 2008 (a method for manufacturing conductive carbonized biomass). In April 2024, a demonstration test was conducted at the Gunma Prefectural Industrial Technology Center regarding the proprietary patent for manufacturing conductive carbonized biomass. The results confirmed the formation of three major recycling processes (new material iomass carbon) and a large amount of biomass gas from the chemical cycle. The demonstration experiment was conducted in an argon atmosphere at 1000°C for 1 hour and 2 hours. In both cases, clean micropores remained, and biomass carbon (new material iomass carbon, one of the three major recycling processes) was formed. A large amount of gas (chemical recycling, one of the three major recycling processes) was generated from a sample with a diameter of 0.5 cm and a length of 3 cm, which is the subject of this additional patent application.

[0012] The methane gasification of CO2 emitted simultaneously from industrial waste (waste tire rubber, plastics, etc.) and the issue of global warming, which was discussed at the UN's COP28, are international themes, and on a global scale, cries of distress can be heard from all over the world due to extreme weather events. My own patent, obtained in 2008 (method for manufacturing conductive carbonized biomass), is already patented as a method for manufacturing new material biomass carbon, one of the three major recycling methods. In April 2024, the Gunma Prefectural Industrial Technology Center conducted further demonstration experiments using samples. The results showed that microporous carbon was clearly detected in the three major recycled materials (wood and bamboo) under conditions of 1000°C in an argon atmosphere for 1 hour and 1000°C for 2 hours. Furthermore, it was found that large amounts of gases such as carbon dioxide, carbon monoxide, and hydrogen could be extracted and recovered.

[0013] A patent has also been completed for a power generation system that can recover large amounts of gas generated from carbon black, which accounts for nearly 40 percent of industrial waste (waste tire rubber and plastics), and generate electricity using that gas. In other words, the method for producing conductive carbonized biomass according to the present invention has been demonstrated using biomass in April 2024 (Gunma Prefectural Industrial Technology Center), and the generation of a large amount of gas was confirmed at that time. This patent involves the use of forestry waste (bamboo, wood, etc.) that is carelessly abandoned throughout Japan, as well as industrial waste (waste tires, rubber, plastics, etc.) that was previously produced from fossil resources like petroleum. However, this represents a shift towards addressing global warming and achieving a circular economy and the Sustainable Development Goals (SDGs). This invention solves the problem of simultaneous recycling (chemical, material, and thermal) of three major types of waste: forestry waste (bamboo, wood) and industrial waste (waste tire rubber, plastics). This is the only way to solve the above-mentioned problems. [Brief explanation of the drawing]
