Abstract:Measurements of the rate constant of CO 2 dissociation on the surface of molten Fe x O-SiO 2 -Al 2 O 3 -Cu 2 O slag have been made by using the 13 CO 2 -CO isotope exchange technique as a function of temperature and imposed equilibrium CO 2 /CO ratio. It is shown that the apparent first-order rate constant remains fixed with Cu 2 O content from 1 to 10 wt% at higher oxygen potentials. The rate constant becomes approximately 2 times higher after metallic copper is reduced from the slag. The effect of temperatur… 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.
