Citrate route to prepare K-doped Li2ZrO3 sorbents with excellent CO2 capture properties / Qiang Xiao in Chemical engineering journal, Vol. 174 N° 1 (Octobre 2011) 

Public ISBD [article]  in Chemical engineering journal > Vol. 174 N° 1 (Octobre 2011) . - pp. 231–235 Titre : Citrate route to prepare K-doped Li2ZrO3 sorbents with excellent CO2 capture properties Type de document : texte imprimé Auteurs : Qiang Xiao, Auteur ; Xiaodan Tang, Auteur ; Yefeng Liu, Auteur Année de publication : 2012 Article en page(s) : pp. 231–235 Note générale : Génie chimique Langues : Anglais (eng) Mots-clés : Nanoparticles  Citrate  CO2  capture  K-doped  Li2ZrO3  Hydrogen  production Résumé : K-doped Li2ZrO3 sorbents with excellent CO2 capture properties were synthesized via a citrate route. The CO2 capture–regeneration properties of these synthesized K-doped Li2ZrO3 sorbents were investigated by thermogravimetric analysis (TGA) at different temperatures and CO2 partial pressures. The synthesized K-doped Li2ZrO3 sorbents possess a better CO2 capture performance than reported Li2ZrO3-based ones, especially at low CO2 partial pressures. At 823 K and a CO2 partial pressure of 0.25 bar, the uptake of CO2 in the K-doped Li2ZrO3 with an optimized K:Li:Zr composition of 0.2:1.6:1 in molar ratio can reach 23 wt.% within 15 min. Furthermore, the sorbent displays a good stability, confirmed by CO2 capture–regeneration cycles.
