Abstract—Catalysis of the supported oxide catalysts in the direction of the methane oxidation reaction is investigated. Modified nickel-containing catalysts studied at the reaction of partial oxidation of methane to synthesis gas. The effect of modifying additives (cerium and lanthanum oxides) on the activity and resistance to coking NiO / γ -Al
2O
3 catalyst was defined. The introduction of cerium and lanthanum oxides increases resistance to catalyst coking. Rising of lanthanum modified catalyst activity associated with a decrease in its recovery temperature and increased dispersion of particles of metallic nickel. It is found that the developed 3% NiO + 2% La

3 can direct the process towards the formation of ethylene.
