Oxidative Coupling of Methane over La-Ba-Sn(Sm,Ce)Catalysts

Abstract

Abstract: The catalytic performance of La-Ba-Sn(Sm,Ce) system catalysts was investigated. The results showed that the addition of Sn, Sm and Ce components significantly improved the catalytic activities and C₂ selectivities for OCM, Furthermore, low calcination temperature was favorable for the low temperature OCM reaction, and high C₂ yields and selectivities were obtained at high calcination temperature and under optimum reaction conditions. In combination with XRD, XPS analysis, it can be concluded that the third components are highly dispersed in the bulk of the catalysts, which is responsible for the OCM.

Key words: La₂O₃, Sm₂O₃, SnO₂, CeO₂, Oxidative coupling of methane
