Definitions
- Thisinvention relates to the production of hydrogen by reacting a mixture of carbon monoxide and steam, and more particularly to such a process involving the useof an improved catalyst.
- the conversion of carbon monoxide with steam is carried out with the aid of catalysts which contain, apart from magnesium oxide and alkali carbonate (preferably potassium carbonate) and carbonaceous substances, as a further constituent iron oxide in the form of native iron ores.
- Red iron ore micaceous iron-ore, haematite, bloodstone, and the like
- ferric oxide FeezOz
- Iron in the form of ferric hydroxides occur in nature in brown iron ores (limonite containing FB403(OH)6, bog iron ores containing FezO(Ol-I) 4, gothite containing FeO(OH), and the like).
- iron ores which yield ferric oxide or ferric hydroxide-under heat, examples of such ores being sideritecontainingFeCOz and magnetite containing Fes04.
- these fourcomponent catalysts also retain undiminished the poison-resisting properties of the known three-component catalysts, more particularly in respect of the commonestcatalyst poison, name-- 1y sulphur, in inorganic ,or organic combination. This state of things shows that the components combine, within the range of proportions here concerned,'to form a new unity having decisive- 1y altered properties.
- the quantity of iron oxides in the mixture required to obtain marked enhancement of the catalytical activity of the three-component catalysts in question depends on the proportions of the other constituents'of the catalyst mass.
- the proportion of iron oxides to-thetotal quantity of MgO +K2CO3 contained in the catalyst should be between 1:30 and 1:2.
- the iron oxide content should preferably amount to at the most of the entire catalyst mass.
- the magnesium oxide used may be in the state of caustic burned or calcined magnesia, or of precipitated magnesia.
- native iron oxide or ferric hydroxide instead of adding native iron oxide or ferric hydroxide to the magnesia it is also possible to start with magnesite rich in iron or its transition states to breunerite (MgCOaFeCOa) without any further addition of iron.
- the catalyst may for example have the following composition:-
- iron oxide in the following claims to include not only oxides but also hydroxides of iron and combinations yielding iron oxide or bydroxide under heat, while the numerical indications refer to ferric oxide (F8203).
- the process of producing hydrogen which comprises causing steam to react with carbon monoxide according to the reaction in the presence of a catalyst consisting principally of a mixture of magnesium oxide, alkali carbonate and carbonaceous substance, and containing a considerably smaller amount of iron oxide in the form of native iron ore, the ratio of the quantity of iron oxide to the total quantity of magnesium oxide and alkali'carbonate in the catalyst being between 1:30 and 1:2.
- the process of producing hydrogen which comprises causing steam to react with carbon monoxide according to the reaction in the presence of a catalyst consisting principally of a mixture of calcined magnesite, potassium carbonate and carbonaceous substance, and containing as an activator a considerably smaller amount of iron oxide in the form of native iron ore, the ratio of the quantity of iron oxide to the total quantity of magnesium oxide and alkali carbonate in the catalyst being between 1:30 and 1:2.
- the process of producing hydrogen which comprises causing steam to react with carbon monoxide according to the reaction in the presence of a catalyst consisting principally of a mixture of calcined magnesite, alkali carbonate and carbonaceous substance, and containing as an activator a considerably smaller amount of iron oxide in the form of native iron ore, the ratio of the quantity of iron oxide to the total quantity of magnesium oxide and alkali carbonate in the catalyst being between 1:30 and 1:2 and the iron oxide content amounting at the most to 10 per cent of the Whole of the catalyst mass.
- a process of producing hydrogen including reacting a mixture of carbon monoxide and steam in the presence of a catalyst prepared from magnesitic material rich in iron by the addition of alkali carbonate and carbonaceous matter, the ratio of the quantity of iron oxide to the total quantity of magnesium oxide and alkali carbonate in the catalyst being between 1:30 and 1:2 and the iron oxide content amounting at the most to 10 per cent of the whole of the catalyst mass.
