Description
Technical field
The present invention relates to a kind of method of making activated carbon structure, this is a kind of framework that can make a good job of absorption and intensity function.
Background technology
Activated carbon has a huge accurate surface-area (about 1500 meters squared per gram), and because of containing many micropores, it is widely used for dispeling the organic substance that is present in the middle of the fluidity substances such as air, water.
Many drawbacks are arranged when using activated carbon.At first, use a parcel or filter cylinder, activated carbon is fixed on particle state by reticulation and similar thing.Can produce the pressure whereabouts that adsorptive power and conversion unit are caused in this case, be very difficult because will control activated carbon certain parcel factor in parcel or filter cylinder.Then, it is interior as sorbing material or catalyzer that activated carbon should be filled in a filter cylinder, and can be dispelled under wind action easily.Secondly, when being used continuously, activated carbon generally is filled in the special instrument, so that carry out the separation after the passivation, still, because activated carbon particle is so little, the pressure that generally can produce instrument falls phenomenon after rise.
In order to overcome above-mentioned drawback, many tests were all carried out, such as: use tackiness agent to make the filterableness structure of likeness in form honeycomb; Increase the volume of activated carbon particle.When using tackiness agent to make activated carbon structure, tackiness agent may stop up its micropore, reduces certain surface-area of this structure, and adsorptive power is had a greatly reduced quality.For example, activated carbon power and water-soluble starch are mixed, form activated carbon structure, and oven dry activated carbon tissue, even these steps all can be very useful when forming a special construction, but tackiness agent has stopped up the micropore of activated carbon structure, cause certain low surface area to dwindle.And in the process of water is arranged, or when surpassing the temperature of combustion of starch, the mode of using starch to make tackiness agent is impracticable.
The bounding force of tackiness agent (such as starch) and activated carbon is very weak, and when the tackiness agent capacity was on the low side, the activated carbon structure that contains starch and activated carbon was easy to destroyed.When the tackiness agent capacity is higher, certain concrete surface meeting step-down of activated carbon, thus destroy adsorptive power.
Therefore, in the carbonate switching process, the tamanori that can change charcoal mixes with activated carbon power or particle, thereby the whole tackiness agent and activated carbon power or particulate material of containing changed into carbon.This method can be carried out under higher relatively temperature, so the reduction of the concrete surface-area of activated carbon is then lower.That is to say, tackiness agent in the carbonate conversion process by carbonating and kept its state, like this since, the steadiness of structure can remain unchanged, the concrete surface area minimizing degree of structure is also low, because the volatile matter of tackiness agent has produced some micropores in the high temperature evaporation process.In a word, tackiness agent serves as thermoplastic resin exactly in this purpose.
The 303rd, No. 239 Korean Patent has disclosed a kind of tackiness agent, is used to make the pitch or the thermoplastic resin of carbon optical fiber filtering type sorbent material such as being used for fixing activated carbon.
When pitch is used as tackiness agent, generally about 400 degrees centigrade, carry out with the postheat treatment of carbon fiber mix.In heat treatment process, pitch is become meso-phase and is attached on the carbon optical fiber.Yet in heat treatment process, because pitch can be transformed into a kind of heat-proof polymer, it does not have micropore is in accordance with expectation.Therefore, just in case certain piece bituminous amount thickness excessive or carbon optical fiber is excessive, the original micropore of carbon optical fiber can stop up, but therefore more further carbon optical fiber micropore may lose activity.Thus, increasing certain concrete surface area is very difficult thing.If dosed that small portion activated carbon powder, just tension intensity increases, but the reduction of concrete surface area is very high.
In addition, the 302nd, No. 472 Korean Patent disclosed and a kind ofly by high-temperature heat treatment tackiness agent has been transformed into the method for carbon, and wherein, thermo-elasticity or thermoplastic polymer be as tackiness agent, and activated carbon powder by this adhesive attachment on inorganic filter or wire netting.In this case, be conditional attached to the activated carbon powder amount on wire netting or the inorganic filter.In addition, owing to can stablize heating at back thermoplastic polymer that thermoplastic polymer is hardened, therefore stable thermoplastic polymer is carried out carbonization may need lot of energy and time.And lower as the output of the thermo-elasticity of tackiness agent or thermoplastic polymer, therefore when increasing binder dosage, specific surface area can reduce.That is to say that although the intensity of activated carbon structure increases along with the increase of tackiness agent, specific surface area can reduce.
As mentioned above, use the tackiness agent that meets conventional related can easily carry out mold.If as tackiness agent, then this tackiness agent may block some micropores with starch, and can reduce the adsorptive power of activated carbon structure.If by as tackiness agent activated carbon powder being adhered to structurally thermoplastic polymer, then by the thermal pretreatment of low temperature more, thermoplastic polymer can decompose, and temperature more Gao Shihui carry out carbonization.In the previous case (use starch), thermal treatment temp may be different because of the characteristic of tackiness agent.And in latter event (use thermoplastic resin), the carbonization meeting consumes plenty of time and energy.
In addition, because the viscosity of this tackiness agent is higher, be difficult to make activated carbon to mix mutually with this tackiness agent, therefore temperature is higher when using traditional method to make activated carbon structure.But also used solvent to dilute the tackiness agent that uses traditional method to make.When using solvent, carburising step can be comparatively complicated.In addition, in heat treatment process, can produce bubble, therefore may not can form activated carbon structure well.Along with adhesive consumption increases, the intensity of activated carbon structure also improves constantly.But tackiness agent may block the micropore of activated carbon, thereby has reduced specific surface area.
Therefore, need a kind of activated carbon structure with high-tensile of design strongly, this structure can be resisted high temperature, and has high absorption capacity, can prolong the commutation period of new texture.
Summary of the invention
Therefore, target of the present invention provides the activated carbon structure with following framework: activated carbon structure has outstanding adsorptive power and intensity in this framework.
Therefore, another target of the present invention provides the activated carbon structure that can make such as different shapes such as honeycomb type, collar plate shape or anchor chain types.
For realizing above-mentioned target, made the activated carbon structure that in structure, has the enhancing framework, so that can make large scale structure, and the intensity that improves structure.In addition, by using the specific surface area that can reduce activated carbon structure as the mixture of the pitch of tackiness agent and activated carbon powder slightly.
In embodiment of the present invention, introduced the making method of the activated carbon structure of band framework, step is as follows: at first, make activated carbon mixture in this ratio of reinforcement material of the activated carbon powder of about 100 weight (wt), the tackiness agent of about 5～40wt, about 5～30wt.Secondly, the framework with predetermined shape is installed in the mold.Then, activated carbon mixture is filled between mold and the framework; Moreover, under 50 ℃～300 ℃ temperature, to activated carbon mixture preheating 10～30 minutes.Then, under rare gas element, put in the smelting furnace activated carbon mixture into (temperature is 400 ℃～1000 ℃) carbonization 1～15 hour.At last, under rare gas element, input steam or carbonic acid gas are with cooling of carbonization mixture and activation.

Embodiment
Hereinafter, will with reference to the accompanying drawings best mode and the first-selected embodiment of the present invention that carries out an invention be elaborated.It should be noted that for graphic simplicity and explanation, can use some reference numbers to come part or like product are marked.
In embodiment of the present invention, introduced the making method of the activated carbon structure of band framework, step is as follows: at first, make activated carbon mixture, this mixture by about 100 weight (wt) in the activated carbon powder partly, the 5～40wt part in the tackiness agent, 5～30wt in the reinforcement material partly form.Secondly, the framework with predetermined shape is installed in the mold.Then, activated carbon mixture is filled between mold and the framework; Moreover, under 50 ℃～300 ℃ temperature, to activated carbon mixture preheating 10～30 minutes.Then, under rare gas element, put in the smelting furnace activated carbon mixture into (temperature is 400 ℃～1000 ℃) carbonization 1～15 hour.At last, under rare gas element, input steam or carbonic acid gas are with cooling of carbonization mixture and activation.
Pre-heating step is in order better tackiness agent to be put in the middle of the reinforcement material.Carburising step must be carried out under rare gas element, and as nitrogen, argon gas etc., this helps preventing fire.If in oxygen, carry out, the thermal treatment meeting danger close in the carburising step.Moreover, by activation carbonization mixture, can enlarge the micropore of activated carbon structure, or remove the material that the activated carbon structure surface does not react, so just can increase concrete surf zone, heat up the activatory step thereby saved passing through in the traditional method.Tackiness agent is a kind of of pitch, creosote, viscid bitumen, gilsonite and their mixtures, can be solid shape or aqueous, can be solid and liquid mixture during use, also can be independent solid or liquid.
Generally speaking, preferably adopt softening temperature to be higher than the Powdered pitch of room temperature.If adopt aqueous pitch, viscosity is an important processing factors.Mix with heavy oil (aqueous creosote wet goods) by intensification or with pitch, may command bituminous viscosity, thus the flowability between control activated carbon and the tackiness agent also is easier to mixed active carbon and tackiness agent.
Embodiment in according to the present invention, when tackiness agent was put into activated carbon powder equably, intensity was constant, and the reduction of concrete surface area can be very low.The intensity height of the part that amount of binder is higher, the reduction of concrete surface area is also very high.The intensity of the part that amount of binder is less is low, and the reduction of concrete surface area is also low.According to embodiment of the present invention, when softening temperature is higher than 60 ℃ pitch when the tackiness agent, pitch is easy to mix with activated carbon and reinforcement material, because pitch is Powdered; When mixed uniformly activated carbon mixture was kept in the environment that is higher than softening temperature, the asphalt powder of uniformly distributing in activated carbon mixture can liquefy, and after the liquefaction, and can be applied to the surface of activated carbon, framework and reinforcement material.Therefore compare with the structure that adopts liquid adhesive to form, this kind texture quality is better, mainly is because adopted uniform mixing.
Coal tar pitch has one 60 to 100 ℃ softening temperature, at room temperature keeps solid state, also has a kind of hydrocarbon mixture of fragrance.This and mixture have polymer weight, so boiling point is very high.And, when the coal tar pitch adstante febre, easy polymerization reaction take place.Coal tar pitch contains phenyl ring on three and carbon one carbochains, so that hydrocarbon ratio uprises, about 1.6-1.9.Therefore, when it is decomposed by thermal treatment, can produce wide variation; Wedding agent is suitable for activated carbon structure.When pitch was used as wedding agent, volatile quantity was very little, thereby made pitch almost become carbon, and carbon transforms power and just increased.So even only use a spot of pitch, the power of activated carbon structure has also increased, carbonization just can take place at short notice.In addition, in the process of carbonization, because the formation effect of volatile component, the decrement of certain surface areas is very little,
According to a function mode of the present invention, the activated carbon structure that has framework comprises the carbon fiber reinforcement material that a length is 1～20mm.Because carbon fiber as reinforcement material, is compared with the situation of only using wedding agent, and activated carbon structure has higher intensity.
According to a function mode of the present invention, framework mainly is steel, stainless steel, nickel, nickelalloy, aluminium, copper and composition thereof.In addition, framework is made of a coarse surface, to strengthen bounding force; Also comprise the asphalt surface course of a thickness more than 0.1mm.Therefore coarse surface has increased surface area, has also increased the bounding force between framework and the activated carbon.Upper layer is to form by the road oil on the framework, and becomes carbon surface layer in carbonization process, thus keep and activated carbon mixture 12 between bounding force.
If framework is a rod-type 31, the diameter of bar is approximately 1～20mm so.If framework is the net formula, Wang thickness is about 0.1mm so, and circle or rectangular opening are about 10mm.
In addition, in the process of making activated carbon mixture, can be supported by activated carbon structure as the precursor of precious metal or golden oxygen catalyst.The consumption of precursor can be controlled according to the purpose of reaction, and has temperature meeting increase in the process of carbonization of the activated carbon of precursor.Then, precursor is decomposed, and activated carbon structure has also just comprised and also just comprised catalyzer.In other words, the step of the activeconstituents of support catalyst can be eliminated, to increase output and to save energy and cost.
