Methane conversion

摘要

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of Ru having combined therewith 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 DEG to 1000 DEG C. Reducible oxides of Ru are regenerated by oxidizing the reduced composition with oxygen. Bulk ruthenium oxides promoted by sodium and/or compounds thereof are particularly preferred contact solids.
