Removal of Chlorinated Chemicals in H2 Feedstock Using Modified Activated Carbon

Removal of Chlorinated Chemicals in H2 Feedstock Using Modified Activated Carbon

Activated carbon (GAC) was impregnated by sodium and used as adsorbent to remove chlorinated hydrocarbon (CHC) gases contaminated in H2 feedstock. 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 wa...
