Hydrocarbon liquids and olefins can be made from methane with greater efficiency than previously available, by converting methane into methanesulfonic acid (MSA), then converting the MSA into a reactive anhydride called sulfene, H<SUB>2</SUB>C-SO<SUB>2</SUB>. Sulfene will exothermically form ethylene, an olefin. It also can insert methylene groups (-CH<SUB>2</SUB>-) into hydrocarbon liquids, to make heavier and more valuable liquids. Other options are disclosed for improved methods of making MSA (such as by using di(methyl-sulfonyl) peroxide as a radical initiator), for converting MSA into products such as dimethyl ether (DME), and for using DME as a "peak shaving" gas that can be injected into natural gas supply pipelines with no disruptions to end-use burners. |
