        All S compounds are removed from the gas (70% CH4 and 30% CO2), H2O vapor is added, and the mixture is passed over granular Ni catalyst at 950.  The CO and H2 produced are converted to MeOH at 2,500 lb. pressure over a granular Zn chromite catalyst.  The MeOH is dehydrogenated to give CH2O, which is dissolved in H2O.
