A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of lead at a temperature of about 500°to 1000°C. The oxide is reduced by the contact and coproduct water is formed. A reducible oxide of lead is regenerated by oxidizing the reduced composit

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of lead at a temperature of about 500°to 1000°C. The oxide is reduced by the contact and coproduct water is formed. A reducible oxide of lead is regenerated by oxidizing the reduced composition with molecular oxygen. The oxide PbO is a particularly effective synthesizing agent.
