[0002] Activated carbon is a specially treated carbon. The organic raw material is heated in an air-tight condition to reduce the non-carbon components. Then it reacts with gas, the surface is corroded, and a structure with well-developed micropores is produced. Since the activation process is a microscopic process, that is, the surface corrosion of a large number of molecular carbides is point corrosion, the surface of the activated carbon has countless tiny pores. The diameter of the micropores on the carbon surface is mostly between 2 and 50nm. Even a small amount of activated carbon has a huge surface area. Almost all applications of activated carbon are based on this feature of activated carbon.

If these waste gases with particles are directly discharged into the air, they will pollute the air. Therefore, it is necessary to conduct secondary treatment on the incompletely burned activated carbon, and at the same time, the waste gas must be subjected to secondary treatment before being discharged into the air to prevent air pollution.
