Abstract:Current studies on the modification of CaO-based sorbents have paid less attention to ion migration resistance within the product layer of CaCO 3 during carbonation. In this work, limestone-derived sorbents with enhanced carbonation reactivity and diffusivity due to the incorporation of Na + ions into the CaO lattice were prepared by a hydrated ion adsorption method. The Na + -ion-modified sorbents exhibited better CO 2 capture capacity and durability. After 30 cycles, Na/Ca-0.10 sorbents still maintained a la… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
