Abstract
An improved method for the oxidative conversion of methane into higher hydrocarbons in which methane and oxygen are continuously and simultaneously cofed into a reaction zone under effective oxidative coupling conditions and contacted with a solid catalyst consisting essentially of a catalyst having a composition of empirical formula Ce.sub.a Na.sub.b Ca.sub.100 O.sub.x wherein a is in the range 0.03 to 2.0, b is in the range of 0.7 to 7.0 and oxygen is present in a molar amount sufficient to fulfill the valence requirements of cerium, sodium and calcium.
