Description
Herstellung hydraulischer Bindemittel Es ist bekannt, aus geeigneten silicatischen Rohstoffen durch Erhitzen, gegebenenfalls unter Zu ratz von kalkhaltigem Material, Bindemittel mit hydraulischen Eigenschaften zu erzeugen. Diese sind dadurch bedingt, daß ein Teil der Kieselsäure in den löslichen Zustand übergeführt wird. Der in Salzsäure lösliche Anteil schwankt mit den Betriebsbedingungen und liegt im allgemeinen zwischen 30 und 500/0.Production of hydraulic binders It is known from suitable Silicatic raw materials by heating, possibly with the addition of calcareous Material to produce binders with hydraulic properties. These are thereby requires that part of the silica is converted into the soluble state. The proportion soluble in hydrochloric acid fluctuates with the operating conditions and lies generally between 30 and 500/0.
Es wurde gefunden, daß man die ganze, in silicatischen Rohstoffen enthaltene Kieselsäure in den salzsäurelöslichen Zustand überführen kann, wenn man die Erhitzung in Gegenwart von Wasserdampf mit einem Partialdruck größer als 12 Torr unter Vermeidung von Oxydation vornimmt.It has been found that all of the silica contained in silicate raw materials can be converted into the hydrochloric acid-soluble state if the heating is carried out in the presence of steam with a partial pressure greater than 12 Torr while avoiding oxidation.
Beispiel i Der benutzte mineralische Rohstoff mit einer Zusammensetzung von 25,00!o S/02, 17,0% Fe203, A1203, 29,00% Ca0, i7,50/0 C02, 2,7% M90, 4,0% S, i,9% Na20, K20 und 2,9% H20 wurde in Gegenwart von 12 % Brennstoff in einem auf 60o bis 700° vorgeheizten Röhrenofen unter überleiten von Zimmerluft mit einem Wasserdampfpartialdruck kleiner als 12 Torr auf i ooo bis i i oo" erhitzt. Nach dieser Behandlung waren 9% der vorher restlos in Salzsäure unlöslichen Kieselsäure in Salzsäure löslich.Example i The mineral raw material used with a composition from 25.00! o S / 02, 17.0% Fe203, A1203, 29.00% Ca0, i7.50 / 0 C02, 2.7% M90, 4.0% S, i, 9% Na20, K20 and 2.9% H20 was in the presence of 12% fuel in one on 60o to 700 ° preheated tube furnace with passage of room air with a water vapor partial pressure less than 12 torr were heated to i ooo to i i oo ". After this treatment were 9% of the silicic acid, which was previously completely insoluble in hydrochloric acid, is soluble in hydrochloric acid.
Wurde der gleiche Rohstoff mit angefeuchteter Luft, deren Wasserdampfpartialdruck größer als 12 Torr war, in sonst gleicher Weise, wie oben beschrieben, behandelt, so war alle Kieselsäure in Salzsäure löslich.Was the same raw material with humidified air, its water vapor partial pressure was greater than 12 Torr, otherwise treated in the same way as described above, so all silica was soluble in hydrochloric acid.
Beispiel 2 Eine Mischung des in Beispiel i benutzten Rohstoffes mit 15 % Kalk wurde in einem stehenden, auf 60o bis 700° vorgeheizten Röhrenofen unter überleiten von angefeuchteter Luft, deren Wasserdampfpartialdruck größer als 12 Torr war, auf i ooo bis i i oo° erhitzt. Die gesamte Kieselsäure war nach dieser Behandlung in Salzsäure löslich. Das angefallene Produkt zeigt ohne weiteren Kalkzuschlag hydraulische Eigenschaften. Beispiel 3 Als mineralischer Rohstoff wurde feuchter Ölschiefer mit der Zusammensetzung von 21,30% S102, i5,ooo/0 Fe203, A1203, 2550% Ca0, 15,00% C02, 2,430V0 M90, 3,43% S, 1,1.7% Na20, K20, 4,17% H20 und 12,000/0 organischer Substanz in einem gut isolierten Schachtofen, der auf 700° vorgeheizt war, unter überleiten von feuchter Luft auf iooo bis i ioo° erhitzt. Nach der Behandlung war die vorher unlösliche Kieselsäure restlos in Salzsäure löslich. Aus dem Abgas wurde durch Kondensation Schwelöl abgeschieden. Die Ölausbeute lag in der Größenordnung wie bei der technischen Schieferschwelung. Auch brennbare Gase können in ähnlicher Weise gewonnen werden.EXAMPLE 2 A mixture of the raw material used in Example 1 with 15% lime was heated to 10,000 to 10,000 ° in an upright tube furnace preheated to 60 ° to 700 °, with humidified air flowing over it, the partial pressure of which was greater than 12 Torr. All of the silica was soluble in hydrochloric acid after this treatment. The resulting product shows hydraulic properties without any additional lime additive. Example 3 The mineral raw material used was moist oil shale with a composition of 21.30% S102, 15, 000/0 Fe203, A1203, 2550% Ca0, 15.00% C02, 2.430V0 M90, 3.43% S, 1,1.7 % Na20, K20, 4.17% H2O and 12,000/0 organic matter in a well-insulated shaft furnace, which was preheated to 700 °, heated to 100-100 ° while passing moist air over it. After the treatment, the previously insoluble silica was completely soluble in hydrochloric acid. Smoldering oil was separated from the exhaust gas by condensation. The oil yield was in the range of the technical slate smoldering. Combustible gases can also be obtained in a similar way.
Das im Rohstoff enthaltene Eisen war zum Teil in diesem Versuch als auch in denjenigen, in welchen die Kieselsäure restlos salzsäurelöslich wurde, in den zweiwertigen Zustand übergegangen.The iron contained in the raw material was partly in this experiment as also in those in which the silica was completely soluble in hydrochloric acid, in passed the two-valued state.
Befeuchtung der Luft ist nicht nötig, falls die Rohstoffe Feuchtigkeit enthalten oder im Laufe der Erhitzung unter Zersetzung Wasser abgeben.Humidification of the air is not necessary if the raw materials contain moisture or give off water with decomposition in the course of heating.
Als kieselsäurehaltiger Rohstoff können schließlich auch die bei der Ölschieferschwelung anfallenden Rückstände verwendet werden.As a raw material containing silica, the Any residues arising from oil shale smoldering can be used.
Das im Beispiel 3 erläuterte Verfahren kann auch so durchgeführt werden, daß das Brennen und Schwelen des bituminösen Gesteins in ein und derselben Vorrichtung zeitlich und räumlich aufeinanderfolgend vorgenommen werden.The method explained in Example 3 can also be carried out in such a way that that the burning and smoldering of the bituminous rock in one and the same device be carried out sequentially in terms of time and space.
