Study on potential biphasic solvents: Absorption capacity, CO2 loading and reaction rate

For its high potential in reducing energy penalty of power plant, the biphasic absorption system for CO2 capture has attracted more and more attentions. Only few solvents, however, are reported to be suitable for this system. Meanwhile, as the previous researchers have pointed out, besides CO2 loading and reaction rate, absorption capacity should also be considered when we evaluate new solvents. In this paper, therefore, 12 potential single or mixed amine solutions for biphasic system are studied by comparing their maximum CO2 loading, absorption capacity, and the reaction rate. The results could be useful in the biphasic CO2 capture system in the future.
