Removal of chlorinated chemicals in Hfeedstock using modified activated carbon

Abstract

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.
