CALF-20 (KAR-F33) Technical Datasheet

Key Properties & Advantages

CALF-20 (KAR-F33)’s superior CO₂ capture performance stems from its zinc-based structure and optimized design:

Exceptional CO₂ Adsorption Capacity & Selectivity: Features a pore geometry (typically 0.5–0.8 nm) and surface chemistry tailored to strongly interact with CO₂ molecules, enabling high adsorption capacity (even at low CO₂ concentrations) and selective separation from flue gas components (e.g., N₂, O₂, H₂O).
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 CO₂ 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.

CALF-20 (KAR-F33) is ideally suited for capturing CO₂ from industrial flue gases:

Flue Gas Treatment: Efficiently removes CO₂ from emissions of power plants, cement factories, and steel mills, even in the presence of water vapor and other impurities.
Industrial Stream Purification: Separates CO₂ from process streams (e.g., biogas, natural gas) to enhance fuel quality or meet emission regulations.

Ambient Air Capture: Demonstrates potential for direct CO₂ capture from atmospheric air, supporting efforts to reduce legacy carbon emissions.
Low-Concentration CO₂ Streams: Effective at capturing CO₂ from dilute industrial exhausts, where traditional adsorbents often underperform.
