In FY2019, we evaluated the direct air capture (DAC) process that uses the KOH-CaCO 3 alkali absorption method. For this proposal paper, we focused on the DAC process involving the adsorption method ...

For the purpose of performance evaluation of the sorbent to be used in DAC (Direct Air Capture), the structure of CO 2 adsorbed on the alkyl amine tethered on the mesoporous silica surface and the ...
