Description
Verfahren zur Herstellung von Wasserstoff Es wurde gefunden, daß man Wasserstoff in einfacher Weise .dadurch herstellen kann, daß man wäßrigen Methylalkohol bei erhöhter Temperatur mit Katalysatoren behandelt, die gleichzeitig spaltend und Kohlenoxyd zu Kohlendioxyd, konvertierend wirken.Process for the production of hydrogen It has been found that Hydrogen can be produced in a simple manner by using aqueous methyl alcohol Treated at elevated temperature with catalysts that cleave and at the same time Carbon dioxide to carbon dioxide, have a converting effect.
Als Katalysator .eignet sich besonders Zinkchromat für sich oder auf Trägern. Die Wirkung des Katalysators läßt sich noch verbessern durch Zusatz geringer Mengen Alkali oder von Oxyden der Metalle der a., 6. oder B. Gruppe des Periodischen Systems.Zinc chromate is particularly suitable as a catalyst, either on its own or on it Carriers. The effect of the catalyst can be further improved by adding less Amounts of alkali or of oxides of the metals of the A., 6. or B. group of the periodic Systems.
Das Verfahren wird bei erhöhter Temperatur, @-orteil'haft bei 300 bis 6oo°, und bei gewöhnlichem oder leicht erhöhtem Druck durchgeführt. Man erhält dabei zunächst durch Spaltung des Methylalkohols ein aus Wasserstoff, Kohlenoxyd und etwas Kohlendioxyd bestehendes Gasgemisch, Idas Spuren von Methan .enthält. In diesem Gemisch wird unter der Einwirkung des gleichen Katalysators und des mit dem Methylalkohol eingebrachten Wassers das Kohlenoxyd in Kohlendioxyd konvertiert, das in der üblichen Weise ausgewaschen wird. Man erhält ein Gas, das nur ganz geringe Mengen Methan (0,a .bis 0,31/o), Kohlenoxyd (0,a bis 0,3'/0) und Kohlendioxyd enthält, .die in bekannter Weise entfernt werden können.The process is carried out at an elevated temperature, @ -orteil'haft at 300 to 600 °, and at normal or slightly increased pressure. First, by splitting the methyl alcohol, a gas mixture consisting of hydrogen, carbon dioxide and some carbon dioxide is obtained, which contains traces of methane. In this mixture, under the action of the same catalyst and the water introduced with the methyl alcohol, the carbon dioxide is converted into carbon dioxide, which is washed out in the usual way. A gas is obtained which contains only very small amounts of methane (0.1 to 0.31 / o), carbon oxide (0.1 to 0.3 '/ 0) and carbon dioxide, which can be removed in a known manner.
Dass Verfahren hat gegenüber den bekannten Verfahren zur Herstellung von Wasserstoff, z. B. aus Wassergas oder durch Elektrolyse, den Vorteil. daß es die Möglichkeit bietet, an beliebigen Orten Wasserstoff auch in kleinen Mengen herzustellen.That method has compared to the known method of production of hydrogen, e.g. B. from water gas or by electrolysis, the advantage. that it offers the possibility of hydrogen at any location, even in small quantities to manufacture.
Beispiel i Wäßriger Methylalkohol, der etwa 5o0/9 reinen Methylalkohol enthält, wird bei etwa 500° über einen Zinkchromatkatalysator geleitet, -der etwa 12 % Chrom enthält. Es entsteht ein Gays, das neben 75,8'/o Wasserstoff 23,50/0 Kohlendioxyd, 0,4% Kohlenoxyd und 0,30/0 Methan enthält. Kohlendioxyd und Kohlenoxyd werden nach bekannten Verfahren durch Auswaschen entfernt. Man erhält so reinen Wasserstoff, der nur noch etwa 0,4% Methan enthält.Example i Aqueous methyl alcohol, which is approximately 50/9 pure methyl alcohol contains, is passed at about 500 ° over a zinc chromate catalyst, -der about Contains 12% chromium. The result is a gay who, in addition to 75.8% hydrogen, 23.50 / 0 Contains carbon dioxide, 0.4% carbon oxide and 0.30 / 0 methane. Carbon dioxide and carbon dioxide are removed by washing out according to known methods. So pure is obtained Hydrogen, which only contains about 0.4% methane.
Beispiel 2 Der nach Beispiel i verwendete wäßrige Methylalkohol wird bei 48ö° über einen Zinkchromatkatalysator geleitet, der nöch 5 0/a Fe2 03 enthält. Aus dem entstehenden Gas, -.das zu 76,2% aus Wasserstoff besteht, wird Kohlendioxyd (23,50/0) in der üblichen Weise ausgewaschen.Example 2 The aqueous methyl alcohol used in Example i is passed at 48 ° over a zinc chromate catalyst which contains an additional 50% Fe2 03. The resulting gas, which consists of 76.2% hydrogen, becomes carbon dioxide (23.50 / 0) washed out in the usual way.
