| Abstract: | Rare earth oxides have been used as catalysts for the oxidative coupling of methane,La_2O_3 and Sm_2O_3 showed higher C_2 selectivity. The mixture of La_2O_3 and alkaline earthoxide was found to be effective for oxidative coupling, among them binary oxide of La-Ba(1: 1) gave the highest C_2 yield, up to 20%. It is suggested that there could be a combina-tion effect of this binary system due to the structural influences, such as the specific sur-face area. Based on the temperature dependence of the products distribution, a mechanism ofthe reaction was proposed. |
