A research team at the Univ. of Wyoming's Soft Material Laboratory has developed a simple, low-cost adsorption process, referred to as Carbon Filter Process, which can capture CO2 and mercury from fluegas generated by coalfired power plants.
CO2 and other pollutants are retained on a porous carbonaceous sorbent at ambient temperature and pressure. This is because such CO2-philic carbonaceous materials are selective to CO2 with respect to nitrogen, especially at lower pressures. After it has been saturated with CO2, the sorbent releases CO2 upon heating to approximately 100°C (e.g., with steam). The sorbent is also known to be effective in removing residual mercury from ...
