Description
Verfabyen zur Herste11uug eines Düngemittels aus natürlichen kalihaltigen Silikaten. Nach einem bekannten Verfahren werden die in kalihaltigen Gcsteinen enthaltenen Alka li,n. durch Glühen eines innigen Gemisches der feingemahlenen Gesteine mit größeren Mengen fc-ingennahlenen Kalksteins größtenteils in wa;;sc#rlöslicher Form erhalte . Es wurde jedoch gefunden, daß cs hierbei nicht nötig ist, die Alkalien unmittelbar in wasserlösliche Form zu bringen. Bei Anwendung schon sehr geringer Kalkmengen erhält man nämlich Doppelsilikate, die zwar nicht in Wasser, wohl aber unter Bildung der entsprechenden. Alkalisalze in Mineralsäuren löslich sind.Ability to manufacture a fertilizer from natural potash Silicates. According to a known process, those contained in potash stones are made Alka li, n. by glowing an intimate mixture of the finely ground rocks with large quantities of fine-grained limestone, mostly in a water-soluble form get . It has been found, however, that the alkalis are not necessary here to bring immediately into water-soluble form. When used, even very less Lime amounts are obtained namely double silicates, which are not in water, but are with the formation of the appropriate. Alkali salts are soluble in mineral acids.
Das Verfahren bietet vor dem bekannten den Vorteil, daß es infolge der Verwendung geringer Kalkmengen selbst aus Gesteinen mit relativ geringem Kaligehalt Düngemittel mit praktisch genügend hohem Kaligehalt gewinnen läßt, was sonst wegen der hohen Verdünnung mit Kalk und Salpetersäure unmöglich ist.The method offers the advantage of the known that it as a result the use of small amounts of lime even from rocks with a relatively low potash content Can gain fertilizer with practically enough high potassium content, what else because of the high dilution with lime and nitric acid is impossible.
Behandelt man das Produkt des Aufschlusses mit Kalk mit feuchten Stickoxydgasen,wie sie z. B. synthetisch hergestellt werden, so werden diese sofort lebhaft absorbiert. Auch kann man die Klinker vorher mit Wasser anfeuchten.If you treat the product of the digestion with lime with moist nitrogen oxide gases, such as she z. B. are produced synthetically, they are immediately vividly absorbed. You can also moisten the clinker with water beforehand.
Außer den beschriebenen können auch andere für die Herstellung von Nitraten bzw. Nitriten durch Absorption nitroser Gase mittels Kalk vorgeschlagene Methoden hier in analoger Weise angewendet werden. Man läßt dieSättigung zweckmäßig nur so weit erfolgen, daß alles Kali sowie der größte Teil des Kalkes umgewandelt ist.In addition to those described, others can also be used for the production of Nitrates or nitrites proposed by the absorption of nitrous gases by means of lime Methods are applied here in an analogous manner. Allow saturation to be appropriate take place only so far that all potash and most of the lime are converted is.
Die gesamte Tonerde und Kieselsäure durchsetzt dann die erhaltenen Stickstoffverbindungen als freie Gallerte hauptsächlich aus Aluminiumsilikat bestehend, was insofern vorteilhaft ist, als dadurch die Hygroskopizität des Produkts verringert wird.All of the clay and silica then permeates the obtained Nitrogen compounds as free jelly consisting mainly of aluminum silicate, which is advantageous in that it reduces the hygroscopicity of the product will.
Technisch führt man das Verfahren am besten so durch, daß man, das Aufschlußprodukt in einem rotierenden, Zylinder den NO-Gasen entgegenführt, wodurch sich bei richtiger Leitung direkt ein trockenes feines Pulver herstellen läßt.Technically, it is best to carry out the procedure in such a way that one, the Digestion product in a rotating cylinder counteracts the NO gases, whereby a dry, fine powder can be produced directly with proper management.
Das erhaltene Düngemittel ist von hervorragender Wirksamkeit, da es nicht nur alles Kali der Gesteine, sondern auch Kieselsäure in einer für die Pflanzen resorbierbaren Form enthält. Ausführungsbeispiel: Das feingemahlene Gestein wird mit etwa.The fertilizer obtained is of excellent effectiveness as it not only all the potash of the rocks, but also silica in one for the plants Contains absorbable form. Embodiment: The finely ground rock is with about.
1/? bis 5/" seines Gewichtes Kalkstein gemischt, briquettiert, und dann am besten genau so wie Kalkstein im Kalkofen gebrannt. Das Brenngut wird gemahlen, angefeuchtet und mit feuchten Stickoxydgasert - die im elektrischen Ofen oder durch Ammoniakverbrennung gewonnen sein können - behandelt, bis der' gewünschte Sättigungsgrad erreicht ist. Aus Feldspat (mit io bis Z2 Prozent Kali) erhält man ein Düngemittel mit etwa 5 Prozent Stickstoff und 6 Prozent Kali, aus Leucit (mit i8.Prozent Kali) können solche mit etwa 5 Prozent Stickstoff und io Prozent Kali hergestellt werden.1/? Mixed, briquetted, and limestone to 5 / "of its weight then best burned in the same way as limestone in a lime kiln. The material to be fired is ground, moistened and with moist nitrogen oxide gas - those in the electric oven or through Ammonia combustion can be obtained - treated until the 'desired degree of saturation is reached. A fertilizer is obtained from feldspar (with 10 to 2 percent potash) with about 5 percent nitrogen and 6 percent potash, from leucite (with 18 percent potash) these can be produced with around 5 percent nitrogen and 10 percent potash.
