The percentage of methane contained in natural gas varieswith the locality, but on an average it is about 94 per cent. Thepercentage of alcohol which may be produced from the gasvaries with the percentage of methane. The processes consistof subjecting the natural gas to an electrically heated Germansilver, closely woven, fine wire gauze coiled and enclosed in anenamel retort. By subjecting the gas to heat and combining itwith oxygen in the presence of steam, which prevents completecombustion and maintains the temperature below the decompo-sition point of alcohol; destructive distillation or oxidation ofthe gas is induced, resulting in the latter being converted intoa fluid containing alcohol, benzol, nitric acid and prussic acid invarying proportions. Referring to the illustration, the German silver gauze, elec-trically heated, is contained in retort Xo. 2, from which distillate. APPARATUS FOR DISTILLATION OF ALCOHOL FROM NATURAL GAS. goes to retort No. 6, where it is partially cooled and condensedand by specific gravity the products of condensation are par-tially separated. These are then passed directly to an airometer7. From the airometer the volatile products are passed underpressure, through a pipe 9 to the outer coil 10 of a water cooleddistillator II, while the condensed or liquid portion of the prod-uct is passed in the form of alcohol and dehydrogenated alco-hol, through a pipe 12 to the inner coil 13 of the distillator, thencedirectly conveyed into a manometer 15, and then drawn offthrough an outlet tube or faucet 16, a specific gravity meter 17being employed, whereby the separation of the liquid into itsvarious constituents is facilitated. For further refining, theproduct of distillation, which has passed to the overflow vessel19 of a vacuum type with an outlet tube 20 may be conductedthrough a filter 21, a
