Abstract

Abstract : From breathing air to flue gas : The cover image illustrates the relationship between the structure of adsorbed carbon dioxide (CO2 ) on an immobilized amine sorbent and the concentration of CO2 from breathing air (400 ppm) to simulated flue gas (15 vol %). In situ infrared spectroscopic study determined the structures and fractions of strongly and weakly adsorbed CO2 on a Class I amine sorbent, which is applicable to CO2 capture from air to flue gas. Elevating the CO2 concentration in the stream increased the CO2 capture capacity, fractions of strongly adsorbed CO2, and the binding energy of adsorbed species. Sorbents that capture CO2 from breathing air can be regenerated by using vacuum regeneration whereas sorbents that capture CO2 from flue gas have to be regenerated by using a thermal swing process. More details can be found in the Full Paper by Yuxin Zhai and Steven S. C. Chuang from the Department of Polymer Science, University of Akron onpage 510 in Issue 3, 2017 (DOI: 10.1002/ente.201600685).
