## Sr-promoted rare earth (viz. La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Er and Yb) oxide catalysts (Sr/rare earth ratio \ 0Γ1) are compared for their performance in the oxidative coupling of methane (OCM) to hydrocarbons and C 2 oxidative dehydrogenation of ethane (ODE) to ethylene at di β erent temperatur
## SUMNARY The role of heterogeneous and homogeneous reactions during the oxidative coupling of methane over Li/MgO was investigated by carrying out experiments at reduced pressure (60 Pa). The conclusion is that the radical reactions occurring in the gas phase play an essential role in the C,, se
## CaO catalysts promoted with various elements were examined systematplly for the oxidative coupling of methane. 10 mol% Li+-CaO and 10 mol% Ba -CaO gave high C2 yield (23 to 26% at 1023 to 1073 K for 10% Li+-CaO) under CH4 and 02 partral pressure of 2.8 an $+1.4 kPa respectively. A three compo
