D. Zhang, Auteur ; B. S. Liu, Auteur ; Y. P. Zhan, Auteur Année de publication : 2009 Article en page(s) : pp. 7498–7504 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : CO2  reforming  Syngas  production  Catalytic  activity Résumé : CO2 reforming of methane into syngas over Sm2O3−La2O3 (SL)-supported Ni catalyst was investigated in a fixed-bed quartz reactor and the best catalytic activity was observed over Ni/SL (sol−gel) due to the reduction of the perovskite LaNiO3 and spinel La2NiO4 to form small nickel particles. The conversion of CH4 and CO2 over Ni/SL(sol−gel) were 55% and 57%, respectively, the selectivity of H2 and CO were 96% and 98%, significantly higher than those over Ni/SL (imp) catalyst at 700 °C and a GHSV of 4.8 × 104 mL·h−1·g−1cat. In the meantime, the Sm2O3−La2O3-supported Ni catalysts were characterized by means of techniques, such as BET, XRD, H2-TPR, TG/DTA, HRTEM, XPS, and XAES.
