CASE 3367 PROCESS AND CATALYST FOR CONVERTING METHANE INTO HIGHER HYDROCARBON PRODUCTS Abstract Methane is converted into higher hydrocarbon products, and especially into ethane and ethylene, by oxidative coupling, by bringing a gaseous mixture containing methane and oxygen into contact at high temperature for a short contact time with a solid catalyst formed from lithium oxide, an alkaline earth metal oxide (preferably of magnesium) and a lanthanide oxide (preferably of neodymium or lanthanum), in which the lithium content is less than 0.20% by weight and the atomic ratio of the alkaline earth metal to the lanthanide varies from 0.8/1 to 8/1, said catalyst being obtained by: - preparing a mixture of lithium, alkaline earth metal and lanthanide oxides in which the lithium content exceeds 1% by weight; and - reducing the lithium content of the mixture to less than 0.20% by weight by high temperature thermal treatment conducted at least partly in an oxidizing atmosphere.
