Carbon Dioxide Recovery from Combustion Flue Gas Using Carbon-Supported Amine Sorbents

75640-This project addresses the environmental problem of the removal and recovery of carbon dioxide (CO2) from combustion/incineration flue gas in order to reduce greenhouse gas emissions. Specifically, carbon-dioxide will be removed from flue gas by using sorbents based on amines that are supported on low-cost activated carbons. Phase I will demonstrate the superior CO2-sorption performance of carbon-supported amine sorbents under simulated industrial conditions. Three tasks will be undertaken: (1) 6¿10 carbon-supported amine sorbents will be developed for CO2 adsorption testing; (2) the sorbents prepared in Task 1 will undergo CO2 sorption and desorption tests to determine the effect of temperature on sorption capacity and to make recommendations for sorbent-regeneration conditions; and (3) an assessment will be conducted to evaluate the concept in terms of comparison with alternative technologies, materials requirements, economics, and life-limiting factors. Commercial Applications and Other Benefits as described by the awardee: The novel technology for the removal of carbon dioxide from combustion/incineration flue gas should be applicable not only to coal-fired power plants but also to municipal, medical, and hazardous waste incinerators. Other related applications include the removal of carbon dioxide from natural gas, especially in small, remote, and off-shore fields.
