Abstract
An absorbent agent is provided. The absorbent agent is particularly for separating carbon dioxide from the flue gas of a fossil-fired combustion device. The absorbent agent comprises a two-component mixture including a free amino acid and an amino acid salt, wherein the free amino acid exhibits a surplus compared to the amino acid salt based on the molar concentration. This creates variability in the PCBN value, which may be attained through different absorption and desorption process temperatures. A method for manufacturing the absorbent agent is also provided.
