It is no exaggeration to say that it is a serious pollution issue next to things. Therefore, the construction of a factory that collects, processes, and recycles waste such as plastics and tires is an extremely necessary and urgent problem because of the advantages of environmental protection and resource reuse. In such waste treatment plants, mainly plastics or tires,
Waste such as rubber is put into a high-temperature pyrolysis furnace, and is thermally decomposed to recover gas, or oil obtained by cooling and condensing this gas to be used as fuel, while solid carbide remaining at the furnace bottom is That is, carbon black is collected or further purified and reused as industrial raw materials such as tires, rubbers and inks. However, in the international market for the time being, the production of carbon black is in an overproduction state, the price is extremely low, and it is currently unprofitable. Furthermore, the quality of the recycled carbon black is low,
Cannot compete with ordinary carbon black in the market. As a result, they must be disposed of as secondary waste,
It also becomes an environmental problem. Besides this, for example, thermal power plants, heavy oil, natural gas or liquefied gas as a fuel brick,
Kiln furnaces for firing ceramics, boiler equipment at factories, etc.
A large amount of carbides such as soot and carbon black, which become pollutants, is generated. If this can be successfully converted into wide-use, high-industrial demand, and high-value-added activated carbon, not only can decay be transformed,
It can bring tremendous benefits.
