The process performance of three amine-functionalized chemisorbents and two physisorbents was evaluated for direct air capture of CO2 in temperature-vacuum swing adsorption and steam-assisted temperature-vacuum swing adsorption cycles. The study showed that physisorbents, generally not studied for DAC, can be promising. Parametric studies revealed that the lack of multi-component thermodynamic and kinetic data impedes the objective evaluation of DAC processes.
