Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of super activated carbon preparation, and specifically is a method for preparing super activated carbon by adopting a blending process. Background Art
[0002] Super activated carbon is supercapacitor activated carbon or carbon electrode material. It is an activated carbon material with a super large specific surface area. The pore structure of super activated carbon is concentrated, the ash content is low, and the conductivity is good. It is widely used in adsorption, electrochemical energy storage and other fields. Super activated carbon can be used to adsorb and catalyze sulfur dioxide to produce sulfur trioxide. Super activated carbon can be regenerated and reused. During regeneration, sulfur trioxide is decomposed into water and dissolved to obtain sulfuric acid.
[0003] At present, the preparation of super activated carbon usually involves a coal-based activation process, in which a chemical activator is used to improve the pore structure of the activated carbon. The traditional method is to use the impregnation method to prepare activated carbon. The impregnation method is to prepare the catalyst into an aqueous solution, and then put the activated coke into it in a certain proportion to make it fully contact. Under the action of surface tension, the active components penetrate from the surface of the activated coke into the pores inside the activated coke, and then are adsorbed by the active points on the surface of the activated coke, and finally loaded on the activated coke. The impregnation method often uses inorganic salt catalysts to impregnate with a saturated solution. During the impregnation process, the impregnation effect can be increased by stirring and increasing the temperature of the impregnation solution, but the active components can only be distributed on the outer surface of the activated coke. The preparation process is complicated and the preparation cycle is long; and during heating and regeneration, the active components on the outer surface of the activated carbon are easy to lose support and fall off, resulting in a significant reduction in catalytic oxidation activity. Summary of the invention
[0004] In order to overcome the above-mentioned defects, the present invention provides a method for preparing super activated carbon by a blending process, which solves the problem that the traditional method of preparing activated carbon by impregnation method can increase the impregnation effect by stirring and increasing the temperature of the impregnation solution during the impregnation process, but the active components can only be distributed on the outer surface of the activated carbon, the preparation process is complicated, and the preparation cycle is long; and during heating and regeneration, the active components on the outer surface of the activated carbon easily lose support and fall off, resulting in a significant reduction in the catalytic oxidation activity.
[0005] To achieve the above object, the present invention provides the following technical solution: a method for preparing super activated carbon by blending process, comprising the following steps:
[0006] S1. The anthracite is sent to the crusher via a belt conveyor for fine crushing. The finely crushed anthracite is sent to a mixing silo for blending with additives. The obtained mixture is ground by a Raymond mill and then sent to a coal powder silo;
[0007] S2, placing the ground mixture in a continuous kneader, adding a binder and water for kneading, and then forming it into columnar wet carbon strips by a flat die rolling granulator, and then granulating it to obtain activated carbon particles;
[0008] S3, drying the activated carbon particles, pre-carbonizing and carbonizing the dried activated carbon particles in sequence, and finally calcining them to obtain carbonized activated carbon particles;
[0009] S4. Add an activator to the activated carbon particles after carbonization. The activator contacts the carbon at high temperature to cause a redox reaction to activate the carbon particles, thereby forming pores in the carbon particles. After the activation is completed, stop introducing the activator and switch to nitrogen protection until it is completely cooled to finally obtain a super activated carbon product.
[0010] As a further solution of the present invention: the blending ratio of the anthracite to the additive is 15-20:2-3, the additive is made of a raw material containing an active ingredient activator, and in S1, the particle size of the mixture after grinding is ≥200 mesh.
[0011] As a further solution of the present invention: in S2, the adhesive is specifically coal tar, and the mass ratio of the ground mixture, the adhesive and water is 30-40:5-8:10-15.
[0012] As a further solution of the present invention: in S3, the activated carbon particles are dried at a temperature of 140-160°C.
[0013] As a further solution of the present invention: in S3, during the pre-carbonization process, the temperature is controlled at 270-280°C, during the carbonization process, the temperature is controlled at 390-400°C, during the calcination process, the temperature reaches 500°C and the activated carbon particles are calcined by external heat supply.
[0014] As a further solution of the present invention: in S4, the activator is one of water vapor and carbon dioxide, and the temperature at which the activator contacts the carbon to undergo a redox reaction for activation is controlled at 700-800°C, and the activation time is 110-120 minutes.
[0015] As a further solution of the present invention: in S4, when the activating agent is water vapor, the flow rate is controlled at 95-100 mL / min, and when the activating agent is carbon dioxide, the flow rate is controlled at 95-105 mL / min.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by using a raw material containing an active ingredient activation material as an additive, the additive is blended with finely crushed anthracite, and the various active elements contained in the additive are utilized to perform variable adsorption catalysis, thereby enhancing the performance of super activated carbon in the application field. Compared with the traditional method of preparing activated carbon by impregnation, this method mechanically mixes the activated carbon before the activated coke is formed, and the loading and activation can be completed at one time. The preparation process is simple, and the active components are evenly distributed throughout the activated coke. At the same time, it has a better function of regulating the pore structure of the super activated carbon. During heating and regeneration, the carbon on the surface of the super activated carbon reacts with sulfuric acid to only cause the catalytic components on the surface of the activated coke to fall off, while the active components inside continue to play a catalytic role, and the internal activation material can also form pores during regeneration, thereby not reducing the catalytic activity of the super activated carbon activated coke.

[0101] Comparative Example:
[0102] The traditional impregnation method is used to prepare super activated carbon: the impregnation method uses an inorganic salt catalyst to impregnate the activated carbon particles with a saturated solution. During the impregnation process, the impregnation effect is increased by stirring and increasing the temperature of the impregnation solution. The active components of the prepared super activated carbon are distributed on the outer surface of the activated coke.
[0103] The following table is obtained based on Examples 1-6 and Comparative Examples:
[0104]
[0105]
[0106] From the comparison in the above table, it can be seen that in Example 3, the super activated carbon is produced by a blending process, and the blending ratio of anthracite to additives is 6:1, and the specific surface area, porosity and desulfurization capacity are the highest. However, the parameters in the comparative example are lower than those in Examples 1-6, and the difference with the parameters in Example 3 is the largest, and thus Example 3 is the optimal preparation process.
[0107] From the above we know:
[0108] By using raw materials containing active ingredient activation products as additives, blending the additives with finely crushed anthracite, and utilizing the various active elements contained in the additives to perform variable adsorption catalysis, the performance of super activated carbon in the application field is enhanced;
[0109] This method allows the super activated carbon to be uniformly mixed by mechanical methods before the activated coke is formed, and the loading and activation can be completed at one time. The preparation process is simple, and the active components are evenly distributed in the entire activated coke. At the same time, it has a good function of adjusting the pore structure of the super activated carbon.
[0110] During regeneration, the carbon on the surface of super activated carbon reacts with sulfuric acid to only cause the catalytic components on the surface of activated coke to fall off, while the active components inside continue to play a catalytic role, and the internal activated substances can also be regenerated during regeneration, thereby not reducing the catalytic activity of super activated carbon activated coke.
