Methane is converted into higher hydrocarbon products by oxidative coupling, by bringing a gaseous mixture containing methane and oxygen into contact with a solid catalyst formed from calcium oxide, magnesium oxide, a lanthanide oxide plus possibly lithium oxide, wherein: the lithium content is between 0 and 0.20 wt%, the calcium/magnesium atomic ratio is between 0.08 and 0.7, and the (calcium + magnesium)/lanthanide atomic ratio is between 0.8/1 and 8/1, and preferably between 2/1 and 4/1. <IMAGE> |
