Abstract: The oxidative coupling of methane was studied over the Li-Ni-Y-O mixed oxide cata-lysts.The effects of the catalyst composition and preparation method and the reaction con-ditions on the activity of LiNi0.7Y0.3O2 and the reaction products were examined.The C2 yield up to 22% at methane conversion of 40% was obtained.The XRD analysis indicatedthat the catalyst was composed of LiNiO2 and LiYO2, showing a synergetic effect on tehreaction.

Key words: methane, oxidative coupling, catalyst, mixed lithium-nickel-yttrium oxide
