Activated carbon odor removal

When the activated carbon is treated by ultrasonic wave, the ultrasonic cavitation will cause shock wave and microjet, and the different ultrasonic treatment time and physical parameters will have different effects on the properties of activated carbon.
Yu Fengwen et al. 1 found that the pore size of activated carbon was changed by ultrasonic modification, and the BET specific surface area and micropore specific surface area of activated carbon decreased slightly with the extension of ultrasonic treatment time.dxd activated carbon
In order to make the activated carbon material have more abundant void structure and more uniform pore size distribution, some activators are often added in the activation process.
The commonly used activators are alkali metals, hydroxides of alkali earth metals, inorganic salts and some acids. At present, the more widely used and more mature chemical activators are KOH, NaOH, ZnCH, CaCb and H.PO, etc."Different activators and their dosages make the preparation of activated carbon more flexible, among which the super activated carbon prepared by KOH as the activator has the best performance.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.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.activated carbon supplier
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.
