Funded Project to Capture CO2 from Flue Gas
The Illinois Clean Coal Institute (ICCI) has selected the Illinois State Geological Survey to develop a biocatalyst-promoted absorption process for the post-combustion CO2 capture from coal combustion flue gases. The main objective of the 18-month, $118,000 project is to develop and evaluate an enzyme catalyst to promote the absorption rate of CO2 in a vacuum potassium carbonate process. The process was developed at the ISGS and is currently patent pending. Particular efforts will be made to evaluate and minimize the impacts of the impurities from the Illinois coal combustion flue gas (such as sulfur and chlorine) on the activity of the catalyst. Immobilization techniques will be developed to maximize the activity of the catalyst immobilized onto selected matrix supports.
