Abstract

There is provided a process for converting methane to higher molecular weight hydrocarbons. In a first step, methane is contacted with elemental sulfur. In one embodiment, carbon disulfide and hydrogen sulfide are produced from this reaction of methane and sulfur, and this product is, in turn, reacted to form CH.sub.3 SH. In another embodiment, CH.sub.3 SH is formed directly in a one-step reaction of methane and sulfur. 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.
