In this work, silica-based CO2 adsorbents were successfully prepared by the sol–gel method. These materials were chemically modified with 3-aminopropyltriethoxysilane (APTES) using the grafting technique. Two synthesis parameters were investigated

Aqueous solutions of alkanolamines are commonly used in CO2 capture processes. To describe these complex processes rigorous mass transfer models are needed, in which all mass transfer, kinetics and thermodynamics are incorporated correctly. To improv
