With an ever-increasing population and unpredictable climate changes, meeting energy
demands and maintaining a sustainable environment on Earth are two of the greatest …

This work provides a comparative technical assessment of three technologies for CO 2
removal from air: two aqueous-scrubbing processes and one solid sorbent process. We …

A potential to decarbonize atmosphere, while simultaneously providing a feedstock for
functional industrial applications, induces a strong economic incentive for direct air capture …

Activated carbon (AC) was prepared from waste tea (WT) and the obtained product, WTAC,
was modified with ethylenediamine (MWTAC). Unmodified and modified WTAC samples …

The concurrent utilization of an adsorbent and absorbent for carbon dioxide (CO2)
adsorption with synergistic effects presents a promising technique for CO2 capture. Here, 1 …

Coalbed methane is an abundant form of natural gas extracted from coal beds. Coalbed
methane is viewed as a cleaner energy source versus petroleum and coal combustion …

Carbon capture and storage (CCS) is a critical technology in mitigating greenhouse gas
emissions and achieving carbon peaking and carbon neutrality goals. Currently, there is a …

Amine-functionalized adsorbents have become a hot topic in research on CO 2 separation
from biogas. However, develo** superior adsorbents with high adsorption capacity and …

A study on the intrinsic kinetics of CO 2 adsorption on solid amine sorbent is performed. For
this, a new experimental method is developed to exclude heat and mass transfer limitations …

Two commercially available CO 2-adsorbent materials (ie, zeolite 13X (13X) and Lewatit®
VP OC 1065 (Lewatit)) were evaluated for their applicability in a continuous temperature …
