Abstract:Ethanol steam reforming (ESR) over a Ni/Al 2 O 3 catalyst prepared by reduction of a NiAl 2 O 4 spinel is a promising alternative route to produce H 2 from biomass. This work deepens into the effect of reaction conditions (450−650 °C, a steam/ ethanol (S/E) ratio of 3−9, and a weight space time up to 1.3 h) and evaluates the time on stream evolution of the yields of H 2 , gaseous byproducts (CO, CO 2 , CH 4 , C 2 H 4 , C 2 H 4 O), and formed carbon/coke. The results are explained taking into consideration the … 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.
