Prof. Arvind Rajendran : The Challenge of CO2/H2O Co-adsorption for Point-Source and Direct Air Capture
Abstract: Post-combustion CO2 capture and direct air capture processes deal with moist gas streams, where removing water can be costly. In fact, dealing with water in these cases is often more challenging than performing CO2/N2 separations. Despite the critical role water plays in adsorptive CO2 capture, few studies quantitatively address CO2/H2O co-adsorption. In recent years, our group has focused on developing experimental tools to quantify CO2/H2O co-adsorption on both phys- and chemi-sorbents. This talk will present our work on CALF-20, the first metal-organic framework (MOF) commercialized for CO2 capture, which exhibits unique CO2-H2O competitive behaviour, and how this insight has advanced our work on other physisorbent metal-organic frameworks (MOFs) for post-combustion CO2 capture, and chemisorbents for DAC.
