An improved method for preparing a catalyst which is superior for converting methane to ethane and ethylene is described. The method involves mixing a solution of a magnesium alkoxide in alcohol with a solution of a lithium compound in alcohol. Preferably, chlorine is introduced into the mixture. A solution of an aluminum alkoxide in an alcohol may also be added to the mixture. The magnesium alkoxide hydrolyzed to produce a gel, and the gel is then calcined to produce the catalyst. Catalysts prepared by this method are superior for converting methane to ethane and ethylene, and have superior selectivities for ethylene and ethane over conventional lithium carbonate/magnesium oxide catalysts.
