Description

[Technical Field]

[0001] We have invented a system that can simultaneously achieve the three major recycling processes for industrial waste (waste tires, plastics, etc.), and we would like to use further inventions derived from this to create business models for national policies for the world and people, such as the Biomass Future Industrial City Initiative, special zones for preventive care, and special zones for eco-towns, in order to achieve the SDGs (realization of a sustainable society). [Background technology]

[0002] The background art patent, a method for producing conductive carbonized biomass, was patented in 2008, and was a patent for a method for producing new material biomass carbon, one of the three major recycling methods that was not considered problematic at the time.

[0003] Patent No. 4079987 Summary of the Invention [Problem to be solved by the invention]

[0004] For a long time, there has been no new technology for simultaneously recycling forestry waste (bamboo, wood) and industrial waste (waste tires, rubber, plastics), and although waste producers, countries, and scientists around the world have been seriously researching, no new technology has yet been discovered. [Means for solving the problem]

[0005] To solve the above problems, Example 1 involves a process of heating industrial waste (waste tire rubber, plastics) using an oily solution (waste salad oil) at a temperature between 100°C and 400°C to turn it into oil, a process of extracting materials that are not dissolved in the oil (metals, carbonized rubber, etc.), and a process of simultaneously recovering gas from the carbonized rubber and other materials in an argon atmosphere (oxygen-free condition) using a high-temperature system at 400°C to 1000°C to obtain carbonized rubber.

[0006] To solve the above problem, Example 2 is a process for heat treating forestry waste (bamboo, wood) using an oily solution (waste salad oil) at a temperature ranging from 100°C to 400°C. Carbonized biomass was obtained through a process of extracting the material that was not dissolved in the oil (hereinafter referred to as carbonized biomass, etc.), and a process of simultaneously recovering gas from the carbonized biomass, etc. at high temperatures of 400°C to 1000°C in an oxygen-free environment.

[0007] In Example 3, which solves the above problem, the carbonized rubber is further treated in an argon atmosphere (oxygen-free state) at a graphite structure formation temperature of 1800°C or higher to obtain conductive carbonized rubber (new material carbon).

[0008] In Example 4, which solves the above problem, the carbonized biomass was subjected to a graphite structure formation treatment temperature of 1800°C or higher in an argon atmosphere (oxygen-free state) to obtain conductive carbonized biomass (new material carbon).

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

[0010] The forestry waste (bamboo, wood) and industrial waste (waste tires, waste plastics) were processed at a graphite structure formation temperature of over 1800°C to obtain conductive carbonized biomass and conductive carbonized rubber. This marks the completion of the SDGs (Realization of a Sustainable Society) Revolution's three major simultaneous recycling systems (chemical, material, and thermal) for forestry waste (bamboo, wood) and industrial waste (waste tires, rubber, plastics).

[0011] This invention is a derivative patent and applies the proprietary patent (a manufacturing method for conductive carbonized biomass) acquired in 2008. As a result of a demonstration test in April 2024 (a proprietary patented manufacturing method for conductive carbonized biomass at the Gunma Prefectural Industrial Technology Center), the three major recycling methods (new material biomass carbon) were confirmed, and a large amount of chemical recycling (biomass gas) was also confirmed. The demonstration test was conducted at 1000°C for 1 hour and 2 hours in an argon atmosphere, and in both cases, clean micropores remained, biomass carbon (new material biomass carbon of the three major recycling methods) was formed, and a large amount of gas (chemical recycling of the three major recycling methods) was generated from a specimen with a diameter (0.5 cm, length 3 cm) for which this additional patent application is filed.

[0012] The methane gasification of CO2 emitted from industrial waste (waste tires, rubber, plastics) and the issue of global warming are international topics, and we are hearing cries of distress from all over the world due to abnormal weather on a global scale. My own patent (for the manufacturing method of conductive carbonized biomass) that I obtained in 2008 has already been patented as a manufacturing method of new material biomass carbon, one of the three major recycling methods. In April 2024, a demonstration experiment was conducted again at the Gunma Prefectural Industrial Technology Center, where samples were brought in and the patent was tested. In both cases, samples were tested at 1000°C for one hour in an argon atmosphere, and at 1000°C for two hours. Microporous carbon was clearly confirmed from the three major recycled materials (wood and bamboo), and it was also 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 the large amounts of gas generated from carbon black, which makes up nearly 40% of industrial waste (waste tire rubber, plastics), and generate electricity from the gas. In other words, the method for producing conductive carbonized biomass of the present invention was demonstrated in a demonstration experiment using biomass in April 2024 (Gunma Prefectural Industrial Technology Center), and the generation of large amounts of gas was confirmed at that time. This patent aims to change the direction of the world from the use of forestry waste (bamboo, wood, etc.) that has been carelessly abandoned all over Japan, and industrial waste (waste tire rubber, plastics) made from fossil resources such as petroleum, towards global warming and the realization of a circular SDGs (sustainable society). This invention solves the three major simultaneous recycling problems (chemical, material, and thermal recycling) of forestry waste (bamboo, wood) and industrial waste (waste tire rubber, plastics). This is the only means to solve the above problems. [Brief explanation of the drawings]
