活性炭吸附法广泛应用于有机废气的净化。当废气中有很多成分时,吸附情况变得复杂。 着眼于印刷,制革和涂料行业的废气中含有苯,甲苯和乙酸等,对活性炭吸附法处理废气的动力学进行了实验研究,并优化了操作参数。探索了固定床吸附器,可为工程设计提供参考。 实验结果表明,纯组分的吸附平衡与Langmuir方程吻合良好。 在多组分吸附的情况下,由于各组分之间的竞争和干扰,具有取代吸附能力的组分可以代替已吸附的另一部分,因此各组分的渗透曲线有明显的变化。 吸附能力相对较弱的组分的渗透点显着提高,而吸附能力强的组分的渗透时间被延迟。www.dxdcarbon.com  本文将EL方程和IAST理论用于多组分吸附平衡的理论预测和分析,并与实验结果进行了比较。 结果表明,至少用EL方程预测的总吸附量与实验结果吻合良好,但用EL方程预测的各部分的吸附量往往会产生正负偏差,平均误差通常在20%以上。 但是,IAST可以很好地消除正负偏差,平均误差小于10%,与实验结果更加吻合。activated carbon wholesale  操作参数表明,活性炭的吸附容量会转移温度,气体速度或湿度的增加而降低。 合适的工作范围是:温度在40℃以内,气体速度在0.1〜0.5 m / s之间,湿度最好不超过40%。 在此范围内,压降与气体速度之间的关系基本符合Ergun方程。

Factors such as [10. For honeycomb activated carbon, the wall thickness is a very important parameter, by changing the wall thickness to improve its adsorption efficiency. Under the same porosity, thickness increases, the honeycomb carbon content per unit volume also will increase, which can improve the adsorption capacity. This is because the wall thickness increases, the fluid channel in the cellular cross-sectional area reduced, so the real surface or volume flow rate will increase. At the same time, the contact between adsorbate and carbon efficiency will, there is a balance between the two. Under the given conditions, the balance will determine adsorption increase or decrease. If the adsorbate at higherthe diffusion rate diffuses to the inside of the honeycomb wall, and the empty adsorption site can be continuously adsorbed, so the thick-walled honeycomb should have better adsorption efficiency and adsorption capacity"Determination of air velocity and cross-sectional area of empty towerThe empty tower gas velocity is the velocity of gas passing through the entire cross section of the adsorber.The selection of air velocity not only directly determines the size and pressure drop of the adsorber, but also affects the adsorption efficiency. If the gas speed is very small, the size of the adsorber is large and uneconomical.www.powdered-activated-carbon.com  If the gas velocity is too large, the pressure drop will increase and the adsorption efficiency will be affected.The optimum gas velocity was determined by experiment.activated carbon pellets wholesale  The adsorption design can not pursue too high adsorption efficiency, the empty tower speed value is reduced, it will make the adsorption bed volume, the amount of adsorbent and equipment cost increased greatly;On the contrary, it is not appropriate to take too large empty tower gas speed. Although the equipment cost is low, the adsorption efficiency drops a lot, and the pressure drop of the system will rise rapidly with the increase of the empty tower speed, resulting in excessive power consumption. Therefore, due to the selection of the appropriate air speed of the empty tower, the most suitable air speed of the empty tower is 0.8~1.2m/s"21, according to the empirical conclusion, this design determines Air velocity of empty tower :U= 1.0m /s.Original conditions:Treatment air volume :Q=20000 m'h, design temperature is 35° C, pressure is 1.01325×103Pa Since the proportion of air in exhaust gas is far greater than that of pollutants, the properties of exhaust gas can be approximately viewed as the thermophysical properties of dry air. Please refer to Appendix 9 of Principles of Chemistry to obtain the following data:Properties of air mixture:Fluid density P;=1.147kg/ m', viscosity u,= 1.94×10-5 Pa.S, specific heat capacity C,=1.005kJ/(kg."C)

Activated carbon catalyst can promote the decomposition of ozone. The consumption rate of liquid phase ozone in activated carbon catalytic secondary oxidation process is 71.2% higher than that in ozone secondary oxidation process. The analysis of the relationship between ozone consumption and organic matter content in activated carbon catalytic secondary oxidation process shows that activated carbon can react directly with ozone or act as a free radical initiator in the process of ozone decomposition, especially when the organic matter content in water is low. When ozone dosage is L mg/L, the MIB removal rate of catalytic secondary oxidation is about L times higher than that of ozone secondary oxidation. When the concentration of ozone in water is about 1.5 mg/L, the catalytic secondary oxidation makes BrO; The concentration decreased by 0.04mg/L.activated carbon for gold recovery  The combined process of catalytic oxidation and activated carbon filtration has higher water purification efficiency. When the influent ozone concentration is 0~0.1 mg/L and influent UV254 is 0.020~0.030 L /em, the average removal rate of UV2sa by catalytic and ozone activated carbon is 30% and 21%, respectively. The removal rate of UV2s4 and DOC by activated carbon filtration is the highest when influent water quality and liquid phase ozone concentration is moderate. The DOC removal rate reached the maximum when the liquid phase ozone relative concentration (O/DOC) was about 0.3. The organic matter content and ozone concentration of activated carbon influent after catalytic oxidation are low, which is beneficial to the adsorption capacity and surface properties of activated carbon. In addition, metal oxides lost by the catalyst can be adsorbed by the activated carbon, which also helps to promote the decomposition of ozone on the surface of the activated carbon. activated carbon wholesale

The kinetic activity value of adsorbent is the main basis for the design of adsorption system. The adsorption rateThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, the adsorption process can be divided intoThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, which can be divided into the following steps www.activated-carbon-pellets.com  (1) External diffusion, the adsorbate from the main air flow through the air film around the particles to the outer surface of the adsorbent; (2) Internal diffusion, the adsorbate from the outer surface through micropores to the surface of the adsorbent microporesactivated carbon manufacturer   (3) adsorption, the adsorbent reached the microporous surface of the adsorbent is adsorbed (4) The desorbed adsorbate diffuses to the main body of the gas phase through internal and external diffusionPhysical adsorption process is generally controlled by internal and external diffusion, chemical adsorption is controlled by both surface dynamics and internal and external diffusion.Because of the complexity of the adsorption process and many influencing factors, it is difficult to derive the rate theoretically, so it is generally determined by experience or model experiment.

Activated carbon surface area of the study is very important, only the BET specific surface area detecting data of active carbon method detected result is reliable, domestic at present there are many instruments can only make direct comparison method of detection, Plant waste is mostly made of plant fiber raw materials, in the plant body under the action of capillary, modified solution absorbed by material whole fully, between fiber is filled with the subtle space, make the dry material volume expansion after soaking wet, and reaction. Because of the water in the raw material, modified solution constitute a polar molecule, with a strong absorption of microwave dielectric properties,Therefore, polar molecules collide and rub violently with microwave frequency, generating a large amount of heat, which makes water and modified solution volatilize rapidly, and generate steam pressure, which explodes out from the inside of the raw material to the outside. This sharp action makes the fiber space of the raw material expand and produce sharp drying.In this way, the raw material has a more obvious pore structure and a larger internal specific surface area than before microwave irradiation. Compared with the traditional heating method, the mechanism of microwave in the preparation process of activated carbon is completely different.It shows its unique advantages: high efficiency, energy saving, uniformity, selectivity, low pollution, high thermal efficiency, low energy consumption, simple process and equipment and small footprint, conducive to automation, low carbon loss, and recovery of useful substances. https://www.activated-carbon-pellets.com
