Mar 01, 2018  Mar 01, 2018  After desorbing from the amine, CO 2 in our procedures reacted with Ca 2+ to form calcium carbonate (CaCO 3). Forming precipitated CaCO 3 is a permanent way to sequester CO 2. Since carbonates have a low energy level compared to CO 2, we expect the developed method to be an economical and energy-efficient process.
