ABSTRACT:
A method for converting methane to higher hydrocarbon products and coproduct water wherein a gas comprising methane and a gaseous oxidant are contacted with a nonacidic catalyst at temperatures within the range of about 700 to 1200.degree. C. A preferred catalyst comprises an alkali component associated with a support material. Results obtained over alkali-promoted solids are enhanced when the contacting is conducted in the presence of halogen promoters.
