The selection of treatment technology should be based on the gas volume, purification requirements, the possibility of recovery, the economy of equipment construction and operation and other conditions. Special attention should be paid to the close cooperation with the process in practical work, so as to achieve comprehensive utilization as far as possible.activated carbon coconut shell  At present, there are three common methods of organic waste gas treatment at home and abroad: liquid absorption method, activated carbon adsorption method and catalytic combustion method. The purification efficiency of liquid absorption method is 60%~ 80%, which is suitable for treating low concentration and large volume of organic waste gas, but there are secondary pollution. The purification rate of catalytic combustion method is 95%, which is suitable for the treatment of high concentration and small air volume organic waste gas. The disadvantage is that it has strict requirements on the treatment object and requires high gas temperature. In order to improve the exhaust gas temperature, it needs to consume a lot of fuel, so the operation cost is very high.activated charcoal wholesale  The purification efficiency of activated carbon adsorption method is 99.2%~99.3%. For the treatment of large air volume and low concentration of organic waste gas, it is agreed that this method is the most mature and reliable technology at home and abroad, but the T art process is too long, the operation cost is high, and it is often more difficult to need a stable steam source.

Electrochemical modification is to change the electrical and chemical properties of activated carbon surface by using micro electric field, so as to improve the adsorption selectivity and performance.It does not need to add chemical agents, does not need to heat, does not cause pollution to the environment, low energy consumption, only a few hundred millivolts, easy to operate.The results show that the adsorption equilibrium of activated carbon is dependent on the electric potential: the adsorption amount of activated carbon increases with the increase of the potential, and the adsorption speed is accelerated;Arpolarity polarization is beneficial to the adsorption of chloroform by activated carbon, while cathodic polarization inhibits the adsorption of chloroform by activated carbon 3-341]. Activated carbon heteroatom carrier and compound modificationActivated carbon has very high stability and good activity, these two basic properties become the activated carbon as a catalyst or catalyst carrier conditions.By introducing certain heteroatoms and compounds on the surface of activated carbon by liquid phase deposition, the adsorption performance of activated carbon can be increased by using the binding effect between these substances and adsorbents.compounds, which has the advantages of increasing the reaction rate and increasing the adsorption capacity.Yang Quanhong et al. 'Using FESO;Activated carbon material was modified.www.powdered-activated-carbon.com  The experimental results show that the surface structure of the activated carbon material modified by FeSO changes: the specific surface area decreases, the surface oxygen content increases, the plane of the random layer graphite carbon net is destroyed to a certain extent, and the ammonia absorption capacity and benzene absorption performance of the sample are greatly enhanced.He ChunHong et al. [reported the research progress of supporting activated carbon materials in the removal of SO; the removal ability of SO was significantly enhanced after supporting Co, Ni, Mg, and V compounds, which was due to the formation of Co(OH)2, Ni(OH)2, Mg (OH)2, and V,0 microcrystals on the surface of activated carbon after supporting, which enhanced the desulfurization activity of activated carbon. imagitarium activated carbon pellets

When the activated carbon adsorbed impurities contained in the water, the dissolved impurities in the water accumulated on the surface of the activated carbon and were adsorbed, but also some of the adsorbed substances left the surface of the activated carbon due to the movement of molecules, and re-entered the water at the same time desorption phenomenon. When adsorption and desorption are in a state of dynamic equilibrium, it is called adsorption equilibrium. At this point, the solute concentration between activated carbon and water (i.e. solid and liquid phase) has a certain distribution ratio. If under certain pressure and temperature conditions, with m grams of activated carbon adsorption solute in the solution, the solute adsorption is X mg, then the number of activated carbon adsorption solute per unit weight q. , that is, the adsorption capacity can be calculated as follows It was found that the contents of volatile compounds and flavor components were related to the type of cigarettes and the amount of tar. The contents of volatile compounds and flavor components were higher in the flue-cured cigarettes than in the mixed cigarettes, and higher in the high tar cigarettes than in the low tar cigarettes. The types of fragrance components in smoke of different types of cigarettes are basically the same, but there are great differences in content. The contents of furfural, furfuryl alcohol, maltol, 5-hydroxymethylfurfural, linolenic acid, methyl linolenic acid, linoleic acid, methyl palmitate and other components in flue-cured cigarettes were significantly higher than those in mixed cigarettes. This is related to the higher carbohydrate content in flue-cured cigarettes. Mixed-type cigarettes contain high content of 3-methylpentanoic acid and nitrogen heterocyclic compounds such as cotinine, ho ah, and methamine due to their formulations of burley tobacco and spice tobacco. The filtering law of activated carbon for different types of cigarettes is basically the same, that is, the filtering efficiency is related to the properties of compounds, especially with the molecular weight and boiling point of compounds. The filtration efficiency of activated carbon on flue-cured cigarettes was lower than that of mixed cigarettes. The adsorption characteristics of pure acetone gas on activated carbon were measured. Langmuir model and Dubinin-Radushkevichv (D-R) model were used to fit the adsorption data, respectively. The Langmuir model and D-R model were compared from the Angle of model fitting accuracy and prediction of adsorption heat. Compared with Langmuir model, D-R model has higher fitting correlation coefficient and lower average relative standard deviation for adsorption data, so the fitting result is better. Based on 10-4-3 potential function, the theoretical adsorption heat of pure acetone gas on activated carbon is 17.9 kJ/mol, which is relatively small, indicating that the adsorption is mainly physical adsorption. The predicted value of adsorption heat of D-R model is 15.8kJ/mol, which is close to the theoretical calculated value, and the predicted value of adsorption heat of Langmuir model is 40.7 kJ/mol, which is much larger than the theoretical calculated value. It is found that the key to predict the filtration efficiency of different compounds is to predict the heat of adsorption of compounds. The filtration efficiency is mainly related to the adsorption temperature v, the amount of activated carbon, pore volume, molecular weight of the compound, collision diameter and energy parameters. The influence of pore size on filtration efficiency and adsorption selectivity can be obtained by analyzing adsorption energy. pelletized activated carbon suppliers   It was found that the contents of volatile compounds and flavor components were related to the type of cigarettes and the amount of tar.

Wood activated carbon in China since the 1970 s, the proportion of total domestic activated carbon production of 80% to 40% of the 90 s, but our country coal resources are relatively abundant, variety complete, and low cost, stable and reliable supply, taking coal base as raw material to the production of coal based activated carbon percentage rise gradually, in the 1970 s and 90 s, coal-based activated carbon in China increased from 15% to 60% of the total amount of active carbon, and present a trend of increasing 1 all the time.activated charcoal suppliers & manufacturers  Therefore, the preparation technology of coal based activated carbon has been widely valued at home and abroad, and has made great development.At the same time, it has improved the performance of coal-based activated carbon products and become the world's largest activated carbon product in terms of production and consumption, accounting for about 70% of the total output of activated carbon in the ancient world.However, due to the protection of the environment and high-quality coal and wood resources, some developed countries have introduced relevant laws and regulations to limit the production of high pollution and high energy consumption of activated carbon, resulting in the production and export of activated carbon gradually reduced;On the other hand, because activated carbon is a resource-consuming, labor-intensive product, the production cost of activated carbon produced in developed countries is high, and its competitiveness in the international market is gradually declining.The activated carbon exported by China is mainly of middle and low grade varieties, with low added value. In order to occupy the international market share, enterprises generally adopt low-price marketing strategy, resulting in the low price of activated carbon in the international market.Statistics show that at present, the average price of China's exported activated carbon is only one quarter of that of the United States.www.wyactivatedcarbon.com   This extremely low selling price, for the activated carbon preparation industry, which relies on resource consumption to a large extent, is undoubtedly a waste of precious data. Activated carbon industry is currently facing the dilemma of low price and resource waste. Due to the rapid development of activated carbon industry in some Southeast Asian countries with relatively rich resources, the export of activated carbon is increasing year by year. International buyers use their sales channels to maliciously undercut prices; Domestic industry standards such as: output, capital, technology, environmental protection and other aspects, low entry threshold, the flood of small enterprises. There are some small enterprises lack of funds, the corresponding preparation technology is backward, in the market shoddy, malicious price. As a result, the precious characteristic resources in the process of preparing activated carbon are wasted, leading to the shortage of high quality raw media.

The treatment of organic waste gas mainly includes two categories: recovery method and elimination method.The main recovery technologies of organic waste gas include: adsorption method, absorption method, condensation method, membrane separation technology and pressure swing adsorption technology.Organic waste gas elimination technology can be divided into two categories: physical - chemical method and biological method.china activated carbon supplier  Physical - chemical methods include thermal destruction, photodecomposition, corona, ozone decomposition, etc.Biological methods include biological filter, biological drip filter, biological scour tower, membrane bioreactor, activated sludge process, etc.The purification rate of activated carbon adsorption method can reach more than 95%, if there is no regeneration device, the operation cost is too high, if the steam recovery, the process is too long,coconut shell based activated carbon  the operation cost is high, the recovery of solvent and water mixture utilization value is not high;Regeneration needs a stable steam source, and the adsorption capacity of activated carbon after repeated adsorption and desorption will gradually reduce, generally use two or three years after the replacement.The purification rate of liquid absorption method is only 60%-80%, and there are secondary pollution problems.The waste gas produced in the production process, mainly of benzene, toluene, xylene, etc., according to the nature of benzene class, this scheme adopts the active carbon as adsorbent to absorb the waste gas, the adsorption bed configuration 2 sets of above commonly, use rotation, when one adsorption bed adsorption of organic adsorption amount of reach regulation, change to another Ⅰ adsorption bed for adsorption purification operation, at the same time to take off one in front of the adsorption bed with regeneration.Desorption is carried out by heating under the action of additional steam, and most of the hotgas released by the tail gas is used for desorption and regeneration of adsorbent in the adsorption bed to achieve the utilization of waste heat.The waste gas volatilized from production is sent to the adsorption tower by centrifugal fan with activated carbon as adsorbent. The gas in the tower is processed through the activated carbon filter layer from right to left and from bottom to top, and the purified gas is discharged into the atmosphere through the exhaust pipe.  The purification rate of catalytic combustion method can reach 95%, but it is suitable for the treatment of high concentration, small air volume and high exhaust gas temperature of organic waste gas, and the gas temperature is higher, in order to improve the exhaust gas temperature, it needs to consume a lot of energy.The most used method is a catalytic combustion method, adsorption, it mainly particles or honeycomb carbon as adsorbent, to ensure the continuity of production, generally set up two adsorption bed used interchangeably, as a result of the switching cycle at least for ld, so adsorption bed volume big, adsorbent dosage, heavy equipment, large investment, operation trouble;As the bed volume is large, it is easy to appear the combustion and explosion caused by the accumulation of adsorption heat.To solve these problems, the adsorber of the existing new device adopts a multi-unit shunt combination structure, and uses a new material -- activated carbon fiber as adsorbent

When the temperature is below 600℃, the specific surface area of carbonized material increases with the increase of temperature.When 600~900℃, the specific surface area reaches a certain value: 250~300 m2/g; when above1000℃, the specific surface area shrinks rapidly. granular activated charcoal  When the carbonization temperature is above 800℃, the reaction performance of carbonized compounds and activation gas gradually becomes weaker, so the carbonization temperature is generally below 1000℃. However, if the residual volatile content and thermal effect are taken into account, the most suitable temperature should be 600~700℃39].coal activated carbon supplier  The carbonized substance obtained from the carbonization process is placed in water vapor or a mixture of water vapor and combustion gas and heat treated at 800~1000℃, which is called the activation process. The commonly used activation gases are carbon dioxide, water vapor, oxygen, etc., due to the oxidation reaction of these gases on the surface of the carbonized substance, eroding the carbonized substance, thus producing a rich porous structure.(2) Chemical method.
