Description

Honeycomb type porous carbon material manufacturing method {METHOD OF PREPARING AN ACTIVATED CARBON HAVING HONEYCOMB STRUCTURE}

The present invention relates to a method for producing a porous carbon material having a honeycomb structure that can be used as an adsorbent in an adsorption process requiring a lower pressure drop than a conventional adsorption process.

The honeycomb material having the adsorption capacity is required in a process in which the pressure drop is large due to a large flow rate or a very high flow rate of the fluid to be treated, compared to a general adsorption tower.

As a manufacturing method thereof, a method of manufacturing a paper containing a carbonaceous adsorbent powder by a process for producing corrugated cardboard is generally used.

Japanese Patent Application Laid-Open No. 1988-319022 discloses a method of manufacturing a paper using a paper stock suspension in which activated carbon powder is dispersed, and assembling it into a cardboard form to construct a cardboard box. The cardboard box has an adsorptive force by the activated carbon powder and thus exhibits an air purification effect. However, the corrugated cardboard thus prepared disperses the activated carbon powder in the suspension of paper stock, and in this process, various components in the suspension solution are adsorbed to the activated carbon powder, thereby losing most of the adsorptive power of the activated carbon powder which can exhibit the adsorptive power. . Therefore, it is difficult to show the effect sufficiently.

Korean Patent Laid-Open Publication No. 2003-0080823 similarly to the above patent, by mixing activated carbon as a filler in a sized pulp to produce a paper to include the activated carbon between the paper fibers, using the same to manufacture a general box and cardboard It is disclosed. However, the paper produced as described above has a problem in that the specific surface area value is greatly lowered to around 100 m 2 / g due to reaction with a sizing agent in the manufacturing process, so that the adsorption force is low.

On the other hand, according to the Republic of Korea Patent Publication No. 2001-0019360, in the manufacture of corrugated cardboard corrugated cardboard filled with activated carbon powder in the bone between the corrugated core and the liner to produce a corrugated cardboard so as not to lose the adsorption power of the activated carbon A method of making a box is disclosed. This method is suitable for use as a material of a box having adsorptive power. However, since the adsorbent is filled in the empty space of the honeycomb molded body, the honeycomb is used to realize the adsorption or catalytic effect by passing gas through the bone of the molded body. It does not have the characteristics of the molded body, the pressure drop is large, and the activated carbon used as the adsorbent is not fixed to the inside of the bone and is simply filled, so it may be lost during processing such as cutting of cardboard or scattered by the passage of gas during use. I have a problem.

According to the Republic of Korea Patent No. 0601094 by the present inventors to solve this problem, the porous paper by the method of laminating paper cardboard in the form of honeycomb, impregnating a solution containing a pitch or thermosetting resin, and heat-treating the honeycomb structure A method for producing a carbon material has been disclosed. This method provides a honeycomb structured adsorbent with a relatively high specific surface area, but since the strength of the raw material is relatively weak because the substrate uses paper corrugated paper, it maintains the honeycomb form during the transportation process. I have a hard time. In addition, some impurities remain in the paper even after the heat treatment, and it is difficult to apply when higher purity activated carbon is required.

An object of the present invention is to solve the above-described problems of the prior art, and in particular, it is difficult to handle in the manufacturing process by using thermoplastic resin and thermosetting resin-based plastic corrugated paper as a raw material while maintaining the advantages as an activated carbon of a conventional honeycomb structure.

The porous carbon material of the present invention is preferably applicable to catalysts or adsorbents used in purification of restaurant exhaust gas, automobile exhaust gas removal, air purification, solvent recovery, and purification of industrial products.

Hereinafter, the present invention will be described in more detail at each step.

Step a): Honeycomb Structure Fabrication Step

Honeycomb structure (honeycomb structure) is a honeycomb hollow hollow form, the adsorbent having such a honeycomb structure has a high specific surface area, not only ensures a gas flow path of a certain space, but also distributes the external force evenly throughout It can withstand external pressure.

The method of the present invention includes a step of manufacturing a honeycomb structure by laminating a thermoplastic resin plastic corrugated cardboard or a thermosetting plastic plastic corrugated cardboard alone or in combination thereof into a plurality of layers.

The corrugated paper used in the present invention is a thermoplastic plastic corrugated cardboard or a thermosetting plastic corrugated cardboard, and is manufactured by the same method as a conventional paper corrugated cardboard manufacturing method, and has a honeycomb structure having a honeycomb cross section by a method of laminating corrugated cardboard and a liner in several layers. You will build a structure.

Figure 1a shows a typical cardboard cross section, Figure 1b shows a honeycomb structure made using the cardboard of Figure 1a.

1A and 1B, the corrugated cardboard 10 is provided with liners 1 and 3 at both sides, and corrugated cardboard 2 is positioned at the center thereof to produce a corrugated cardboard 10 having wavy bones. The honeycomb structure 100 having a honeycomb structure in cross section is manufactured by a method of stacking the corrugated core 2 and the liners 1 and 3 by using a corrugated cardboard 10.

The honeycomb structure 100 may be manufactured by a method of treating a base paper for cardboard, which is commonly used in the field of producing cardboard, with an adhesive, which is not described in detail in the present invention.

In the present invention, in the case of laminating several layers of the corrugated cardboard, an adhesive is applied, and the adhesive used may be an adhesive generally used in the manufacture of corrugated cardboard, but a final adhesive may be used when using a thermosetting resin-based adhesive. The strength of the honeycomb structured activated carbon product is maintained stronger.

As the corrugated cardboard material used in the present invention, corrugated cardboard made of thermoplastic resins such as polypropylene, polyethylene, polyvinyl chloride, and polystyrene, which are generally used, can be used as it is, and made of corrugated cardboard using various thermosetting resins and used as raw materials. Can be. Furthermore, it is also possible to laminate and use a cardboard made of thermoplastic material and a thermosetting material.

As such, the plastic corrugated cardboard material used as a raw material is heat-treated in a subsequent process, so that an adsorbent of carbon material is manufactured, and only the carbon component is left by heat treatment in a subsequent process as well.

Step b): impregnation step

The present invention includes impregnating the honeycomb structure in an impregnation solution comprising a pitch, a thermosetting resin, and a mixture thereof.

The impregnation solution is suitably adjusted in viscosity so that the compound is evenly applied to the honeycomb structure by dissolving a pitch or a thermosetting resin in an organic solvent. Since the pitch or the thermosetting resin has a certain viscosity, it serves as a binder to facilitate the bonding to the honeycomb structure and maintain the strength of the porous carbon material of the final honeycomb structure, as well as heat treatment in a subsequent process to the carbon component It remains and constitutes a porous carbon material.

The pitches usable in the present invention are not particularly limited in kind, and may be both pitches synthesized from coal tar or petroleum heavy oil, and pitches synthesized from petroleum pitch or other organic matter.

The thermosetting resin used for the impregnation is also not particularly limited, phenolic resin (furicyl alcohol), furfuryl alcohol (furfuryl alcohol), urea resin (urea resin), melamine resin (alamine resin), alkid resin (epoxy), epoxy At least one resin selected from the group consisting of an epoxy resin and an unsaturated polyester resin can be used, and preferably a phenol resin is used.

The organic solvent may be used as long as it is possible to dissolve the thermosetting resin used for the impregnation while maintaining the shape of the thermoplastic resin-based corrugated cardboard substrate, and is not particularly limited in the present invention. In the case of impregnating the honeycomb structure of the thermosetting resin system, since it is manufactured and stabilized through a curing step at the time of manufacture of the corrugated cardboard, it is not dissolved in an organic solvent for dissolving the thermosetting resin used for the impregnation, and thus can be used without any limitation.

The impregnation process of this step impregnates the honeycomb structure provided in step a) into the impregnation solution so as to contain a sufficient amount of pitch or thermosetting resin.

At this time, the impregnated amount of the pitch or thermosetting resin contained in the honeycomb structure is used in a ratio of 0.1 to 10 times the weight of the honeycomb structure. If the weight ratio is less than 0.1 times, the honeycomb structure is difficult to manufacture because the thermoplastic resin substrate is softened in the heat treatment process, making it difficult to maintain the structure. When the weight ratio is 10 times or more, the size of the corrugated cardboard forming the honeycomb structure is large. Even if the bone is filled with a pitch or a thermosetting resin, there is a problem that is difficult to manufacture as a honeycomb form.

At this time, in the case of using the thermosetting resin dissolved in the organic solvent as the impregnation solution, before the subsequent heat treatment step to perform a curing process so as not to have a viscosity to facilitate the handling of the honeycomb structure impregnated in the thermosetting resin. You may. The curing is performed by applying heat at a suitable temperature according to each impregnating resin used, and may be used by adding a curing agent commonly used for curing each thermosetting resin, if necessary, the use of such a curing agent is commonly used in this field. It may be chosen and used appropriately by those with knowledge of

In the case where the pitch is included in the impregnation solution, the solvent is evaporated to perform the subsequent heat treatment step so that the pitch used by the conventional method does not have viscosity at room temperature, and thus the handling is easier. This step is not necessary in the construction of the process, but it is possible to prevent the honeycomb structure impregnated with the pitch or the thermosetting resin from being interfused in a subsequent process.

On the other hand, when the plastic corrugated cardboard material in step a is manufactured using a thermosetting resin, the carbonization yield is high in itself and thus has an adsorption capacity by treatment of a subsequent step, so that the impregnation step of this step can be omitted.

In addition, the activated carbon powder may be further contained in the pitch or the thermosetting resin in addition to the above. The activated carbon powder is a powder whose surface is oxidized in an oxidizing atmosphere, and has a specific surface area and includes fine pores, and thus has excellent adsorptive capacity.

The activated carbon powder may be added in less than three times the weight of the pitch or thermosetting resin to improve specific surface area, thereby preparing a high-performance product. If the content ratio is more than three times, the pitch or thermosetting resin is not preferable because the effect as a binder with the corrugated substrate is not sufficient, so that the adhesive bonding strength is weak.

Step c: carbonization step

The present invention includes the step of carbonizing the honeycomb structure by heat treatment.

This step is a process in which the honeycomb structure is heated at a high temperature to remove tar and volatile components in the pitch or thermosetting resin, leaving only fixed carbon. In this carbonization step, a carbonization process which is commonly used in preparing an adsorbent is performed.

The carbonization process is carried out in an inert atmosphere, preferably in a nitrogen atmosphere, in order to prevent oxidation of the honeycomb structure and to prevent pore closure on the particle surface due to a decrease in mechanical strength or rapid heating.

At this time, the carbonization temperature is preferably carried out at 600 to 1200 ℃ and the temperature increase rate to the temperature preferably has a range of 0.1 to 20 ℃ per minute. If the carbonization temperature is less than 600 ℃, it is difficult to expect the carbonization effect even if the honeycomb structure is treated for a long time, and if it exceeds 1200 ℃, even if the treatment for a short time, the crystallization proceeds so that the reaction does not occur well in the subsequent activation process. .

In addition, if the temperature increase rate up to the carbonization temperature is less than 0.1 ℃, the temperature increase process is too long, the crystallization proceeds in the temperature increase process, and thus the reaction is less likely to occur in the subsequent activation process, and also unnecessary energy consumption This is undesirable. When the temperature increase rate up to the carbonization temperature exceeds 20 ° C., the thermoplastic resin-based corrugated substrate is rapidly thermally decomposed, so that it is difficult to maintain the structure. Thus, the thermosetting resin layer coated on the surface is destroyed together by the impregnation process, and the honeycomb structure is generally It is not preferable because it becomes difficult to maintain the shape and also becomes very low in terms of carbon yield.

This carbonization process may omit this carbonization process when the honeycomb structure is impregnated with a large amount of pitch or thermosetting resin whose strength can be sufficiently maintained in the activation step, and the impregnation amount that can omit such carbonization process is honeycomb. It is a case where it is 0.2 times or more with respect to the weight of a structure. However, if the carbonization process is omitted, the yield and strength of carbon may be lowered. Therefore, the carbonization process is preferably applied even when the strength required by the product is not high.

Step d: Activation Step

The present invention includes the step of activating the honeycomb structure by heat treatment in a steam, air or carbon dioxide atmosphere.

Activation is a process of increasing the specific surface area of a porous carbon material by developing a fine pore structure by heat treating the honeycomb structure at high temperature to erode the surface of carbon (or fixed carbon) of the honeycomb structure.

The activation process is performed by heat-treating the honeycomb-shaped carbon structure obtained in the carbonization step at a temperature of 600 to 1200 ° C. under steam (H ₂ O), air, or carbon dioxide (CO ₂ ) atmosphere.

If the temperature of the activation process is less than 600 ° C., the activation reaction proceeds very slowly and takes a long time. On the contrary, when the treatment is performed at a temperature exceeding 1200 ° C., the reaction may occur so rapidly that an overall oxidation reaction may occur. Therefore, it is not preferable in the maintenance of structure and control of reaction.

However, when a large amount of activated carbon powder is added to the impregnation solution, the previous carbonization step alone may cause the porous carbon material to be partially activated to have a sufficient degree of adsorptivity. Therefore, different adsorption forces are required depending on the use, so that only the carbonization step may be performed or the activation step may be performed to suit the use.

As described above, the porous carbon material having the honeycomb structure produced by the method of the present invention has adsorption capacity over the entire portion of the material. Therefore, the present invention can be suitably applied as a catalyst or adsorbent for use in purifying exhaust gases of restaurants, automobile exhaust gas removal, air purification, solvent recovery, and purification of industrial products. In addition, the porous carbon material has a high specific surface area, and the gas flow path is secured intact in the bone, so that the porous carbon material can be utilized as an adsorbent in an adsorption process requiring a lower pressure drop than a conventional adsorption process.
