| titleOfInvention | Methane conversion to methanol |
| abstract | Disclosed are a method and apparatus with alternate embodiments that use commercial chemical free radical initiators to directly convert methane to methanol in a low energy, one step, catalytic reaction. In one embodiment an apparatus converts “packets” of methane gas to liquid methanol. Methane gas and aqueous hydrogen peroxide are injected into the packet apparatus through valved ports and mixed in a structurally robust, rotating reaction chamber coated with metal cation catalyst. Although operating at low temperature and pressure, the rotating chamber is sufficiently strong enough to contain spontaneous ignition of the mixture should that occur. The reactive oxygen species, primarily hydroxyl radicals, released in the chamber of mildly elevated temperature, oxidize the methane molecule, replacing one hydrogen atom on its molecule with one stable hydroxyl OH molecule, converting vapor methane CH 4 to vapor methanol CH 3 OH. Vapor exiting the exhaust port condenses on ambient temperature drip screens to stable liquid methanol. An alternate continuous process embodiment uses flow-through conversion screens coated with immobilized dry chemicals. Water vapor entering the apparatus releases molecular oxygen from screens coated with dry urea hydrogen peroxide. A circulating endless belt screen is used to continual recoat the dry urea hydrogen peroxide. Reactive oxygen species are generated on successive conversion screens through which the molecular oxygen, and methane gas entering the apparatus, must pass. Metal cation catalyst molecules physically entrapped within interstitial cavities of a three dimensional, fixed porous colloidal matrix coating on the screens create powerful hydroxyl radicals from the molecular oxygen. These reactive species in turn convert methane molecules impacting the conversion screens to methanol molecules. The method and apparata operate at modest temperature, pressure, and energy requirement levels, and are scalable from portable units to industrial scale methanol refineries. |
