Adsorption effect of nonpolar small molecules and carbon layer on activated carbon02021-09-14 01:10:33
Activated carbon adsorption, is the use of activated carbon on the solid surface of the water adsorption or a variety of substances, in order to achieve the role of water purification. The adsorption of activated carbon is produced in two aspects.One is that the molecules inside the activated carbon are subjected to equal forces in all directions while the molecules on the surface are subjected to uneven forces.This makes other points adsorbed on its surface, which is physical adsorption;The other is due to the chemical action between activated carbon and adsorbed substances, which is chemical adsorption.The adsorption of activated carbon is the result of the comprehensive action of the above two kinds of adsorption.activated charcoal pellets  When the adsorption speed and desorption speed of activated carbon in the solution is equal, that is, the number of activated carbon adsorption is equal to the number of desorption, the concentration of the adsorbed material in the solution and the concentration on the surface of activated carbon are no longer intermingled, that is, to achieve the balance, the dynamic balance at this time is called activated carbon adsorption balance. www.chinactivecarbon.com

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 manufacturers  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.dxdcarbon.com  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. In view of these problems, combined with the characteristics of this graduation design and only body requirements, the use of activated carbon fixed bed adsorption system for industrial organic waste gas purification, the selection of honeycomb activated carbon as adsorbent.The process system is compact and integrated with adsorption and desorption.

The isobarisothermal adsorption properties of activated carbon at different temperatures, at different pressures and at different flow rates were determined by using the gas produced in the system as samples.The adsorption effluent curve of benzene by activated carbon was plotted.activated carbon gold mining  The effects of different temperature on the regeneration performance of activated carbon under static environment, the effects of steam at different temperature on the regeneration performance of activated carbon under dynamic environment and the effects of nitrogen at different temperature on the regeneration performance of activated carbon under dynamic environment were studied.activated carbon company  The experimental results showed that high pressure and low temperature were beneficial to the adsorption, and the flow rate had little effect on the equilibrium adsorption capacity in the range of experimental flow rate. The adsorption capacity of benzene by activated carbon in the experiment was 150~170mg/g under operating conditions. At the same time, the filtration and adsorption properties of coke were tested. The experiment shows that the adsorption performance of the test coke on benzene is very weak, can not be used as the nitrogen adsorbent, but the coke filter and adsorption performance of ash and naphthalene is very good, the content of naphthalene and ash after the gas through the coke column completely meet the design requirements. The results show that the combined use of coke and activated carbon in the gas system can completely achieve the purpose of removing benzene, naphthalene and ash. According to the above research results, a coke filter was designed. The application of the equipment solved the problems that the feedstock gas compressor in the urea blackening unit could not run for a long period due to the vibration caused by the scaling of the rotor, the blockage of the flow channel and the problems that the naphthalene formation in the heat exchanger affected the heat transfer effect. 
What is granular activated carbon0ceciliacheng2022-03-02 23:27:16
Although the term granular activated carbon is generic, it can refer to ten similar but not identical adsorbents. Activated carbons perform differently in various applications, depending on factors such as raw materials, methods, and degree of activation. Granular activated carbon is a very versatile group of adsorbents capable of selectively adsorbing thousands of organic and certain non-organic materials. yrd carbon From the medicinal use of powdered carbon in ancient Egypt, to the charred interior of whisky casks, carbon has been activated and used as a sorbent for hundreds of years. Granular gas-phase activated carbon media was first widely used in military gas masks of World War I and, in the interwar years, commercially in solvent recovery systems. Granular liquid-phase activated carbon first found significant application in sugar decolorization and antibiotic purification after the First World War. Today, there are hundreds of applications—thousands of ongoing applications if the various uses under the general heading of environmental control are counted individually Granular activated carbon dxd carbon is an adsorbent derived from carbonaceous feedstocks that thermally or chemically removes most of the volatile non-carbon components and part of the original carbon content, resulting in structural domains with high surface activity. The carbon structure obtained from purchasing activated carbon blocks may be a relatively regular network of carbon atoms derived from the cellular arrangement of the raw material, or it may be an irregular block of microchips, but in either case the structure will have openings to allow electrons to pass through. Under microscopic magnification, it is a sponge-like structure. The characteristic of the carbon surface coconut shell activated carbon price per ton   is that it is non-polar, that is, it is essentially electrically neutral. This non-polarity gives the activated carbon surface a high affinity for relatively non-polar adsorbates, including most organics. As an adsorbent, activated carbon contrasts in this respect with polar drying adsorbents such as silica gel and activated alumina. Granular activated carbon has limited affinity for water through capillary condensation, but not the surface attraction of desiccant to water.
