ABSTRACT:
A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with a reducible oxide of Tb. The Tb oxide is preferably combined with an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectivity to higher hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Tb are regenerated by oxidizing the reduced composition with molecular oxygen. The oxide Tb.sub.4 O.sub.7 is particularly effective in the process.
