Abstract
There is provided a process for converting methane to carbon disulfide. More particularly, methane is decomposed to form elemental carbon and elemental hydrogen, and the elemental carbon is reacted with sulfur to form carbon disulfide. Carbon disulfide may then be contacted with hydrogen, optionally in the presence of more methane, under conditions sufficient to produce CH.sub.3 SH. This CH.sub.3 SH may then be contacted with a sufficient catalyst, such as a zeolite, especially ZSM-5, under conditions sufficient to produce hydrocarbon having two or more carbon atoms.
