COMPOSITIONS FOR ABSORBING CARBON DIOXIDE, AND RELATED PROCESSES AND SYSTEMS

摘要

A carbon dioxide absorbent is disclosed. The absorbent compostion contains a liquid, non-aqueous, silicon-based material, functionalized with one or more groups that reversibly react with CO2 and/or have a high-affinity for CO2; and at least one amino alcohol compound. A method for reducing the amount of carbon dioxide in a process stream is also described. The method includes the step of contacting the stream with the carbon dioxide absorbent composition. A power plant that includes a carbon dioxide removal unit based on the carbon dioxide absorbent is also described.
