Lanthanide oxide obtained by heating a lanthanide hydroxide and by calcinating, useful as a catalyst in the conversion of methane to higher hydrocarbons, preferably in the oxidative coupling of methane to ethane or ethylene

摘要

Lanthanide oxide obtained by heating a lanthanide hydroxide at 800[deg] C with a heating rate of 4-6 K/minute, followed by calcination at 800[deg] C for 30-90 minutes, is claimed.
