Abstract

AtT ⩽ 650 °C carbon dioxide either formed during reaction or added to the system increases the selectivity for the desired hydrocarbon products during the oxidative coupling of methane and the oxidative dehydrogenation of ethane reaction over Li+/MgO catalysts. Similarly, CO2 inhibits secondary reactions of CH3-radicals with the surface of the Li+/MgO. The improved selectivities are attributed to the poisoning effect that CO2 has on the secondary reactions of alkyl radicals with the surface.
