Among the four examples (B, C, and 2), example (A) is considered to have the best effect. Therefore, if we want to implement this example, what instruments are needed for the present application? This can be done by purchasing i.

C1 Effect of the invention (a) Hot water can be produced by removing heat from the industrial waste treatment of scrap tires, and since the burned residue contains benign activated carbon, activated carbon can also be effectively produced.

b. High-quality activated carbon can be obtained at low cost using waste tires without requiring a gas activation process. (The price is about 1/10 of that of conventional activated carbon.) Since the so-called C8 process can be simplified, there is no cost burden for producing activated carbon.

d. When using activated carbon, soak the activated carbon in water24.
Use over time. This is because the air trapped in the adsorption pores is removed by the pressure of the water.
