چکیده
|
Activated carbon (gac) was impregnated by sodium and used as adsorbent to remove chlorinated hydrocarbon (chc) gases contaminated in hfeedstock. the adsorption was carried out in a continuous packed-bed column under the weight hourly space velocity range of 0.8-1.0 hr-1. the adsorption capacity was evaluated via the breakthrough curves. this modified gac potentially adsorbed hcl and vcm of 0.0681 ghcl/gadsorbent and 0.0026 gvcm/gadsorbent,respectively. it showed higher adsorption capacity than sioand alballs for both organic and inorganic chcs removal. in addition,the kinetic adsorption of chlorinated hydrocarbons on modified gac fit well with yoon-nelson model. © 2015 prapaporn luekittisup et al.
