Abstract

A considerable increase in the global atmospheric CO₂ concentration has raised concern about climate change and has led to a worldwide effort in R&D on control of CO₂ emissions. The separation of CO₂ from flue gas of a gas-/coal-fired power plant was studied. The composition of the gas-fired flue gas was 7.4-7.7% CO₂, 14.6% H₂O, ∼ 4.45% O₂, 50 ppm CO, 420 ppm NO_x, 420 ppm SO₂, and 76-77% N₂. CO₂ could be selectively separated from the flue gases of power plant by using the novel "molecular basket" adsorbent MCM-41-PEI-50. The adsorbent hardly adsorbed any N₂, O₂, and CO. The selectivity of CO₂/NO_x was 2.5 for gas-fired flue gas and the selectivity of CO₂/SO₂ and CO₂/NO_x were 10.7 and 2.86 for coal-fired flue gas, respectively. Very little NO_x and SO₂ desorbed after adsorption indicating the need for pre-removal of NO_x and SO₂ from the flue gas before capture of CO₂ by the PEI based "molecular basket" adsorbent.
