Carbon Fiber Molded Body

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to specially formed carbon fiber bodies (molded objects) that are produced via a specific process involving fiber formation (such as electrospinning), shaping, and then carbonization. These carbon fiber moldings have been optimized to act as highly selective and efficient adsorbents for a wide range of gases. Their unique structure provides superior adsorption properties, making them particularly effective for gas purification, separation, and storage applications.

Use CasesContent extracted from patent full text and abstract with AI.

• Purification of industrial gas streams (e.g., removing CO2 from combustion gases or biogas).
• Separation of gas mixtures in chemical and petrochemical industries (e.g., separating oxygen from air, separating ethylene from ethane).
• Gas storage and enrichment systems, including hydrogen, methane, or ammonia storage.
• Gas adsorption devices used in pressure swing adsorption (PSA), temperature swing adsorption (TSA), or electric swing adsorption (ESA) systems.
• Water vapor adsorption and drying applications (gastrocknung).
• Environmental remediation (removal of pollutants and trace gases from air or industrial emissions).
• Integration into columns, gas adsorbers, or packed bed reactors for air treatment or gas processing.
• As reinforcing additives for plastics, elastomers, ceramics, or concrete for enhanced material properties.

BenefitsContent extracted from patent full text and abstract with AI.

• Tailored and high selectivity for various gases, allowing targeted adsorption and separation.
• Improved volumetric and gravimetric adsorption capacity due to the specially packed and porous structure of the molded carbon fiber bodies.
• Excellent flow and handling properties (abrasion resistance, free-flowing), facilitating easier industrial use in gas separation columns or reactors.
• High stability against moisture and impurities compared to other adsorbent classes (e.g., zeolites or metal-organic frameworks).
• Lower pressure drop across packed beds, reducing energy consumption and operational costs in industrial processes.
• Adjustability of adsorption properties via control over the carbonization process, enabling customization for specific gas targets.
• Comparatively low manufacturing costs and scalable production methods (using common polymers and solvents).
• Material versatility: usable for a broad spectrum of gases, such as CO2, CH4, NH3, H2, CO, N2, O2, hydrocarbons, and various pollutants.
