Advanced Carbon Capture Methods Using Catalysts and Absorbents

Carbon capture technology is the next step in addressing climate change by reducing the amount of carbon dioxide (CO₂) released into the atmosphere from industrial sources. Among the various methods employed, the use of catalysts and absorbents has shown significant promise. These methods leverage the properties of specific materials to enhance the capture and storage of CO₂, thereby improving efficiency and effectiveness.

Catalyst and Absorbent Applications in Carbon Capture

Catalysts and absorbents have the ability to selectively interact with CO₂ molecules. The efficiency of these materials is often determined by their surface area and porosity, which facilitate the adsorption of CO₂. Various materials serve as effective sorbents, including solid amine-based adsorbents, carbon-based adsorbents, zeolites, metal-organic frameworks (MOFs), and alkali metal carbonates.

• Solid Amine-Based Adsorbents: These materials involve immobilizing amines on solid supports, providing high CO₂ capture capacities due to the chemical interaction between the amine groups and CO₂. The use of mesoporous silica, carbon, and certain polymers enhances the performance of these adsorbents by offering high surface areas and proper porosity​.
• Carbon-Based Adsorbents: Carbon materials such as activated carbon, carbon nanotubes, and graphene are known for their high surface area and ease of functionalization. These properties make them suitable for CO₂ capture, especially when modified to increase alkalinity through nitrogen doping or the addition of amine groups.
• Zeolites and MOFs: These materials are crystalline structures with high surface areas and tunable porosity. Zeolites, in particular, are effective at low temperatures, while MOFs can be tailored for specific CO₂ capture applications due to their modular nature​.

Granulation Technologies: Pelletizers and Spheronizers

Granulation technologies like LCI’s extruders and spheronizers enhance the properties of absorbents used in carbon capture. The production of granules with good packing characteristics, low friability, and high absorbent properties help make CO₂ capture systems the most efficient.
