Metal Monolithic Amine-Grafted Zeolites for CO₂ Capture
Project # FC26-07NT43086

Primary Performance Organization
University of Akron

This project will investigate a novel carbon dioxide (CO₂) capture system that involves the integration of a metal monolith with amine-grafted zeolites. The goal of the project is to develop a highly efficient and low cost CO₂ capture system for coal-fired power plants. The results of the investigation will provide parameters to a material and energy balance model for accurate determination of the cost for scale-up of this innovative CO₂ capture system.

Because of the high value of end products, current aqueous amine and membrane technologies are only cost effective for the separation of CO₂ from natural gas in the liquefaction and ammonia synthesis processes. When used for CO₂ capture from coal-fired power plants, however, these current technologies result in substantial increases in the cost of electricity produced.

The cost of CO₂ capture and storage could be reduced if an effective CO₂ capture sorbent is developed with the following three qualities:

• High CO₂ adsorption capacity.
• Long term regeneration capacity in a power plant flue gas environment.
• Low energy requirement for regeneration compared to large amounts of energy required for the aqueous amine process.

These three qualities will be the broad objectives of this project. The potential economic advantages of this particular study revolve around the use of metal monoliths coated with a low cost amine grafted zeolite, which eliminates the use of corrosive liquid amine and decreases the energy required for sorbent regeneration.

This project will continue into 2010, recognizing that coal-fired power plants under anticipated federal carbon emissions regulation will require increasingly efficient and much lower cost CO₂ capture systems.
