Carbonization Process
The carbonization process is actually the dry distillation process of materials under low temperature conditions.
In this process, the material is gradually heated in a certain low temperature range and under the condition of air isolation. The low molecular substances in the material are volatilized first, and then a series of complex physical and chemical changes will occur. The physical changes are mainly dehydration, degassing and drying; The chemical changes are mainly thermal decomposition and thermal polycondensation. The oxygen bond binding group of the organic compound in the material is destroyed, and the oxygen element is separated out in the form of H2O, CO, CO2, and other gases, while forming aromatic compounds and crosslinked high-strength carbon molecular structure solids.
In the carbonization process, noncarbon materials such as oxygen and hydrogen are discharged during the high-temperature decomposition of the material, and the carbon atoms are recombined to form an ordered material with a basic graphite microcrystalline structure. This crystal is composed of hexagon arranged carbon atom planes, and their arrangement is irregular. Therefore, gaps between microcrystals are formed, which are the initial pores of the carbonized material. The purpose of carbonization is to make the material form a secondary pore structure that is easy to be activated and give it the mechanical strength required to withstand the activation process.
Activation Process
The principle of carbon activation is to use water vapor, flue gas, and other oxygen-containing gases as activators to contact with carbon at high temperature to generate carbon monoxide, carbon dioxide, hydrogen, and other hydrocarbon gases. Through the gasification reaction of carbon, many pores are formed in carbon particles.
The activation reaction belongs to the multiphase reaction of the gas-solid system. The activation process includes physical and chemical processes. The whole process includes the diffusion of the activator in the gas phase to the outer surface of the carbonized material, the diffusion of the activator to the inner surface of the carbonized material, the gasification reaction on the surface of the carbonized material to produce intermediate products, the decomposition of the intermediate products into reaction products, the desorption of the reaction products, and the diffusion from the inner surface of the carbonized material to the outer surface.
Reactivation Process
At present, the most widely used and most mature industrial regeneration method of activated carbon is the heating regeneration method.In the regeneration process of activated carbon, according to the changes of organic matter when heated to different temperatures, it is generally divided into three stages: drying, high-temperature carbonization, and reactivation.
The drying stage is mainly to remove the volatile components on the activated carbon.
The high-temperature carbonization stage is to boil, vaporize and desorb part of the organic matter adsorbed on the activated carbon; A part of the organic matter undergoes decomposition reaction and generates small molecular hydrocarbons for desorption; The residual components remain in the pores of the activated carbon and become “fixed carbon”. At this stage, the temperature will reach 800-900 ° C. in order to avoid oxidation of activated carbon, it is generally carried out in vacuum or inert atmosphere.
In the next activation stage, gases such as CO2, Co, H2 or water vapor are introduced into the reactor to clean the micropores of activated carbon and restore its adsorption performance. This stage is the key to the whole regeneration process. Thermal regeneration is widely used because of its high regeneration efficiency.
