Synthesis, characterization and performance of single- component CO2-binding organic liquids (CO2BOL) for post combustion CO capture

摘要

Global demand for fossil fuel is rising tremendously as a consequence of this CO2 emission is increasing exponentially. In order to mitigate the environmental effects of this CO2 emission, an efficient capture technology is required. Current industrial technology utilizes alkanolamines such as monoethanolamine (MEA) that bind post combustion CO2 effectively as aqueous carbonates and bicarbonates. However, to minimize corrosion effects the concentration of MEA rarely exceeds 30 wt% in water, leading to low CO2 gravimetric capacities (≤ 7 wt%). Given the high specific heat capacity of water this 30 wt% MEA means there is a large energy penalty incurred during the CO regeneration process.
