Method for the methane chemical conversion into C2 hydrocarbons

摘要

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 CeaNabCa100Ox 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.
