3D simulation of carbon monoxide purification with CuCl(7.0)/AC by pressure swing adsorption process

P. Sharafi; E. Salehi; H.R Sanaeepur; A. Ebadi Amooghin

Volume 19, Issue 4 , December 2022, Pages 20-37


  In this work, the separation of carbon monoxide (CO) from a synthesis gas (syngas) mixture was modeled. It was considered a copper-based adsorbent consisting of cuprous chloride (CuCl) on an activated carbon (AC) support (CuCl/AC) in a pressure swing adsorption (PSA) process. First, the adsorption of ...  Read More
