Abstract

The interaction of methane with the oxidized surface of the KNaSrCoO3−x is first order in methane with respect to formation of higher hydrocarbons and zero order with respect to formation of CO2. At the initial stage the rate of formation of the reaction products is independent of the amount of oxygen from the catalyst consumed (up to 5–7 monolayers of oxygen), after which the rate of the reaction falls linearly. The overall amount of oxygen consumed in the reaction reaches 30 monolayers.
