Abstract

The potential of a highly loaded mesocellular silica supported polyethyleneimine sorbent to capture CO2 from air was investigated under a set of isothermal conditions between 36 °C and 81 °C. The highest capacity, 1.29 mmol/g, was observed at temperatures of 46 °C and 52 °C. At temperatures lower than 46 °C, the uptake of CO2 appeared to be limited by gas diffusion resistances, while at temperatures above 52 °C the uptake appeared to be limited by the thermodynamics of the reaction between CO2 and amines.
