Reaction chemistry between aqueous sulfuric acid and solid sodium borohydride / Qinglin Zhang in Industrial & engineering chemistry research, Vol. 48 N°3 (Février 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°3 (Février 2009) . - p. 1603–1607 Titre : Reaction chemistry between aqueous sulfuric acid and solid sodium borohydride Type de document : texte imprimé Auteurs : Qinglin Zhang, Auteur ; Richard M. Mohring, Auteur Année de publication : 2009 Article en page(s) : p. 1603–1607 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Chemical  hydrides  Sulfuric  acid  --  reaction  chemistry  Solid  sodium  borohydride  --  reaction  chemistry Résumé : Chemical hydrides represent a class of promising hydrogen storage materials. Solid sodium borohydride in particular offers superior fuel stability and its reaction with acid provides a new approach for hydrogen generation. In this study, the chemistry involved in a hydrogen storage system based on solid NaBH4 and aqueous H2SO4 was studied experimentally. Factors influencing hydrogen generation dynamics, sodium borohydride conversion, and borax byproduct distributions were studied. A fuel-only energy density of 2310 Wh/kg (on the basis of lower heating value of hydrogen contained) is projected for hydrogen storage using pure sodium borohydride and 31 wt % H2SO4.
