Abstract
A process for the preparation of ethane and ethylene by oxidation of methane with oxygen at a temperature of 600.degree. to 900.degree. C., in which lead (II) oxide is used as catalyst (a) dispersed on a carrier of pumice, silicon carbide, zinc oxide, zirconium dioxide, and/or oxides of alkaline-earth elements, or (b) in a mixture with manganese (II) oxide dispersed on a carrier of pumice, silicon carbide, silicon dioxide, titanium dioxide, zirconium dioxide, zinc oxide, and/or oxides of alkaline-earth elements, or (c) without a carrier in a mixture with sodium silicate alone or in combination with silicon dioxide, titanium dioxide, zirconium dioxide, manganese (II) oxide, zinc oxide, and/or oxides of alkaline-earth elements. Ethane and ethylene are obtained with this process in high selectivities with good catalyst activities.
