Description

Key Properties & Advantages
CALF-20 (KAR-F33)??s superior CO? capture performance stems from its zinc-based structure and optimized design:

Exceptional CO? Adsorption Capacity & Selectivity: Features a pore geometry (typically 0.5?C0.8 nm) and surface chemistry tailored to strongly interact with CO? molecules, enabling high adsorption capacity (even at low CO? concentrations) and selective separation from flue gas components (e.g., N?, O?, H?O).
Humid Condition Stability: Maintains structural integrity and adsorption efficiency in moist environments??critical for post-combustion systems, where flue gases often contain high water vapor content.
Thermal Stability at Moderate Temperatures: Withstands temperatures up to 200??C, ensuring durability in industrial capture processes without compromising adsorption performance.
Low-Energy Regeneration: Requires relatively low temperatures for CO? desorption, reducing energy consumption compared to traditional adsorbents (e.g., amines, zeolites)??a key advantage for large-scale, cost-effective carbon capture.
Zinc-Based Safety: Zinc??s low toxicity and environmental compatibility make it suitable for applications requiring minimal ecological impact, distinguishing it from heavy metal-based MOFs.
Core Applications
Post-Combustion Carbon Capture
CALF-20 (KAR-F33) is ideally suited for capturing CO? from industrial flue gases:

Flue Gas Treatment: Efficiently removes CO? from emissions of power plants, cement factories, and steel mills, even in the presence of water vapor and other impurities.
Industrial Stream Purification: Separates CO? from process streams (e.g., biogas, natural gas) to enhance fuel quality or meet emission regulations.
Carbon Capture from Dilute Sources
Ambient Air Capture: Demonstrates potential for direct CO? capture from atmospheric air, supporting efforts to reduce legacy carbon emissions.
Low-Concentration CO? Streams: Effective at capturing CO? from dilute industrial exhausts, where traditional adsorbents often underperform.
