Description

The manufacturing apparatus of high quality activated carbon and its manufacturing method TECHNICAL FIELD

The present invention relates to an apparatus for producing high quality activated carbon using a vertical activation furnace having a stirring and transport means and a method for producing the same. It relates to an apparatus for producing high-quality activated carbon and a method for producing the same, which includes means for transporting and stirring the activated carbon upwardly by a reactor, and performing activation of high-temperature activated carbon in which steam or an inert gas is uniformly injected in the lower part of the reactor.

The quality of activated carbon produced by the conventional technology is mainly suitable for water treatment or air pollutant adsorption, and high-performance capacitors for MCDI (Membrane Capacitive Deionization) have improved the performance of the module by using the ion exchange membrane for the recent CDI electrode. For the purpose of use, medicine, or adsorption of special materials, higher performance is required than the quality of conventional activated carbon. It is a condition that requires technology to produce such high-quality activated carbon.

Activated carbon is a material that has strong adsorption properties and is composed of carbonaceous material, and is widely used as an adsorbent for water treatment, atmospheric use, or as a decolorizing agent. Although there are several types of activated carbon source materials such as palm-based, coal-based, and pitch-based, coconut-based and coal-based materials are mainly used in air pollution prevention facilities and water pollution prevention facilities. Recently, in response to the demand for high-quality activated carbon for special purposes, a lot of research and development is being conducted because pitch-based activated carbon can more easily implement a high specific surface area. In most activated carbon production processes, the activation process is sequentially performed after carbonization. However, in particular, in the case of a pitch system, it is known that it is possible to directly activate a pitch material without a carbonization process, so it is a subject of special interest.

Activation is the most important in the activated carbon production process, and there are physical activation and chemical activation. Physical activation is a method of performing activation using gases such as _{CO 2} , H _{2 O, and chemical activation is a method of activation using chemicals such as KOH, NaOH, H 3} PO ₄ and ZnCl, depending on the activation method and process conditions. Depending on the cost and pore structure are different.

In general, physical activation develops pores with a wide distribution including micro (~2 nm), meso (2-50 nm), and macro (50 nm~) pores, but has a low specific surface area, and chemical activation develops pores with a narrow distribution of micro pores However, it is characterized by a high specific surface area. The specific surface area improvement by the physical (steam) activation process is due to the development of the mesopore structure, and the physical activation is cheaper than chemical activation. Most of the activated carbon used in electrode materials for EDLC, which requires high capacitance, is made by chemical activation. In particular, KOH is widely used because it can obtain the highest specific surface area, but it is rather inappropriate because of the narrow pore distribution of micropores. In order to overcome this problem, the related industry has tried to secure a high filling amount and stability of steam activation at the same time by using a phenol-based polymer precursor, but the situation is still insufficient due to difficulties in steam activation. That is, it is intended to manufacture activated carbon having a wide range of surface area and micropore porous structure with a specific surface area of 1200 to 2000 m ^{2 /g and a pore radius of 1 to 100 nm.}

The activation method of such activated carbon is a chemical method, where KOH or zinc chloride solution is added to charcoal powder to permeate it, and then heated to 600° C. to 700° C. under anoxic conditions to carbonize, or as a physical activation method, when steam is blown into charcoal or coal 800 It can be formed by heating to ℃ to 1200 ℃. The physical activation method is cheaper and is mainly applied to mass production.

In addition, the conventional activated carbon activation device consumes a lot of energy to provide a high temperature, and the device for handling high temperature is also composed of a refractory material, so high facility cost and maintenance cost are required.

An example of such a technique is disclosed in Documents 1 to 3 and the like.
