Abstract

There is provided a process for converting methane to higher molecular weight hydrocarbons. In a first step, methane is contacted with elemental sulfur under conditions sufficient to produce carbon disulfide. Carbon disulfide from this step is then contacted with methane and hydrogen under conditions sufficient to convert methane and to produce CH.sub.3 SH. This CH.sub.3 SH is then contacted with a sufficient catalyst, such as a zeolite, especially ZSM-5, under conditions sufficient to produce hydrocarbons having two or more carbon atoms.
