Description
Verfahren zur Herstellung von Wasserstoff durch Reduktion von Wasserdampf. `Vorliegende Erfindung betrifft die Herstellung von Wasserstoff durch Reduktion von Wasserdampf, und zwar dadurch, daß man. auf letzteren Quecksilber oder niedere Quecksilberoxyde bei einer Temperatur einwirken läßt, die der Verdampfungstemperatur des Quecksilbers mindestens gleich ist. Es ist allerdings früher beobachtet worden, daß Quecksilberdampf sich rri: Wasserdampf nicht umsetzt, aber diese Beobachtung bezog sich nur auf ein luftfreies Gemisch die3er beiden, Dämpfe. Trägt man keine Sorge, die Luft eigens auszuschließen, arbeitet man also unter in der Praxis gegebenen Bedingungen, so tritt die erwähnte Umsetzung ein. Die hieraus sich erge:;ende Tatsache, daß QueckEilberdampf sich in Gegenwart feuchter, heißer Luft oxydiert, kann aber, wie der Erfinder ermittelt hat, nicht ohne weiteres zur Reduktion von Wasserdampf nutzbar gemacht werden, sondern man muß bei einer Temperatur; arbeiten, die der Verdampfungstemperatur des Quecksilbers mindestens gleich ist, so daß also der Wasserdampf überhitzt ist.Process for the production of hydrogen by reducing water vapor. The present invention relates to the production of hydrogen by reduction of water vapor, by the fact that one. on the latter mercury or lower Allow mercury oxides to act at a temperature which is the evaporation temperature of mercury is at least the same. However, it has been observed earlier that mercury vapor does not convert water vapor, but this observation referred only to an airless mixture of the two, vapors. You don't wear one Worry about excluding the air yourself, so one works under what is given in practice Conditions, the aforementioned reaction occurs. The result:; end fact, that mercury vapor is oxidized in the presence of moist, hot air, but it can as the inventor has determined, not readily for the reduction of water vapor be made usable, but one must be at a temperature; work that the The evaporation temperature of the mercury is at least the same, so that the water vapor is overheated.
Um das Verfahren praktisch durchzuführen, erhitzt man z. B. Quecksilber in einer Retorte bis zur Verdampfung. Der ,entstehende, mindestens 36o° C warme Quecksilberdampf wird mit Wasserdampf von gleicher Temperatur gemischt. Das Verhältnis von Quecksilberdampf zum Wasserdampf beträgt theoretisch 20o: 18 Gewichtsteile, kann aber je nach Temperatur .oder Druck davon abweichen.. Das sa erhaltene, aus Wasserstoff und Wasserdampf nebst gewissen Anteilen Luft bestehende Gemisch, das noch Quecksilberoxyde und ein -wenig unverändertes Quecksilber enthält, wird in einem Gegenstromapparat mittels frisch zuströmenden Wasserdampfes abgekühlt, der so auf die Reaktionstemperatur gebracht wird. Wenn nun eine genügende Mange Quecksilberoxyd sich in den Gegenstromapparat abgesetzt hat, schaltet man ihn aus und erhitzt ihn unter vermindertem Druck. Das Quecksilberoxyd zersetzt sich sodann, worauf das regenerierte Quecksilber wieder herausgenommen und zur Reduktion frischer Anteile Wasserdampf benutzt wird. Man verwendet zweckmäßig zwei oder mehr Gegenstromapparate der erwähnten Art gleichzeitig. Der eine kann immer im Betriebe sein, um die entstehenden Quecksilberoxyde aufzunehmen, während der andere zwecks Zersetzung des Quecksilberoxydes erhitzt wird.In order to carry out the process in practice, z. B. Mercury in a retort until it evaporates. The resulting, at least 36o ° C warm Mercury vapor is mixed with water vapor at the same temperature. The relationship from mercury vapor to water vapor is theoretically 20o: 18 parts by weight, but can vary depending on the temperature. or pressure .. The sa obtained, from Hydrogen and water vapor, together with certain proportions of air, that still contains mercury oxides and a little unchanged mercury, is in a countercurrent device cooled by means of freshly flowing water vapor, the so brought to the reaction temperature. If now there is a sufficient quantity of mercury oxide has settled in the countercurrent device, it is switched off and heated under reduced pressure. The mercury oxide then decomposes, whereupon the regenerates Mercury removed again and water vapor to reduce fresh proportions is used. It is expedient to use two or more countercurrent devices of the ones mentioned Kind at the same time. One of them can always be in the company to deal with the mercury oxides while the other heats to decompose the mercury oxide will.
Um Verluste an oxydischem oder metalli; schem Quecksilber durch den Wasserstoffstrom zu vermeiden, geht dieser zweckmäßig nach Austritt aus den Gegenstromapparaten durch einen Waschturm oder besser durch einen zur Abscheidung von Staub mittels. Elektrizität dienenden Apparat.To avoid losses of oxidic or metallic; shem mercury through the To avoid a flow of hydrogen, this is expediently done after exiting the countercurrent apparatus by a washing tower or better by means of one for the separation of dust. Electricity-serving apparatus.
