Description
Verfahren zum Schwelen von fein zerkleinertem fossilem Holz Das Hauptpatent 67q. 8 i 9 betrifft ein Verfahren zur 'Herstellung von Leicht- und Schwerölen und Wasserstoff, wonach fein zerkleinertes Holz mit Ätzalkalilauge innig vermischt, das Gemisch mit Erdalkalioxyden versetzt und das Ganze brikettiert wird. Die Briketts werden dann einer Spülgasschwelung mit Wasserdampf oder anderen kohlensäurefreien Gasen von q.oo bis q.50° unterworfen.Process for smoldering finely chopped fossil wood. The main patent 67q. 8 i 9 relates to a process for the 'production of light and heavy oils and Hydrogen, after which finely chopped wood is intimately mixed with caustic alkali, alkaline earth oxides are added to the mixture and the whole is briquetted. The briquettes are then a flushing gas smoldering with steam or other carbonic acid-free Subject to gases from q.oo to q.50 °.
Es -wurde nun gefunden, daß fossiles Holz, wie solches beispielsweise im Betrieb von Braunkohlenbrikettwerken als störender Bestandteil in der zur Verarbeitung kommenden Trockenkohle anfällt, einen besonders geeigneten Rohstoff für dieses Verfahren darstellt. Unterwirft man dieses fossile Holz bzw. lignitische Braunkohle, gegebenenfalls nach entsprechender Trocknung und Zerkleinerun&, dem Verfahren des Hauptpatents, so kann man mit wirtschaftlichem Nutzen die dort näher angegebenen Erzeugnisse erhalten.It has now been found that fossil wood, such as, for example in the operation of lignite briquette plants as a disruptive component in the processing Coming dry coal accrues, a particularly suitable raw material for this process represents. If one submits this fossil wood or lignitic brown coal, if necessary after appropriate drying and shredding, the process of the main patent, in this way the products specified there can be obtained with economic benefit.
Dieses Verhalten des fossilen Holzes im alkalischen Holzaufschlußverfahren war bei der über unendliche Zeiten ausgedehnten Lagerung des fossilen Holzes unter Luftabschluß und bei- der Möglichkeit einer weitgehenden Veränderung auch durch andere Einflüsse nicht ohne weiteres vorauszusehen.This behavior of the fossil wood in the alkaline wood digestion process was under the extensive storage of fossil wood over infinite times Exclusion of air and both the possibility of extensive change also through other influences cannot be foreseen easily.
Es war überraschend, daß man auf solche Weise einen Abfallstoff nutzbringend verarbeiten konnte.It was surprising to find that a waste material could be useful in such a way could handle.
Das Verfahren -wird beispielsweise -wie folgt ausgeführt: iooo kg fossiles Holz mit einem Feuchtigkeitsgehalt von etwa i o o'o werden mit goo kg 5oo(oiger Ätznatronlauge innig in einem heizbaren Mischgefäß verrührt und diesem Gemisch tooo kg Calciumoxyd zugesetzt. Die fein durchmischte :Masse läßt man in einem isolierten Behälter etwa 6 Stunden Jagern-und zieht sie darauf zur Brikettierung auf einer geeigneten Brikettiervorrichtung ab. Die, -Briketts werden einem mit Wasserdampf als Spülmittel arbeitenden Spülgasofen zugeführt, wobei der Wasserdampf mit einer Temperatur von .loo bis .f5o" in den Schwelofen eintritt. Aus dem Gasstrom scheidet man die gebildeten Destillate und den anfallenden Wasserstoff ab. Dem in fester Fortn erhaltenen Destillationsrückstand entzieht man zunächst durch einen Auslaugeprozeß das Ätznatron und unterwirft die ausgelaugten Briketts, die nunmehr- aus kohlensaurem 1a11 und fein verteilter Holzkohle bestehen. einem Brennprozeß. Das erhaltene Calciumoxy-d dient nach Feinmahlung mit der erhaltenen Ätznatronlauge zu neuem Aufschluß von fossilem Holz.The method is carried out, for example, as follows: iooo kg Fossil wood with a moisture content of about i o o'o are combined with goo kg 5oo (oiger Caustic soda intimately in a heatable Mixing vessel stirred and tooo kg of calcium oxide were added to this mixture. The finely mixed: mass leaves they are hunted in an insulated container for about 6 hours and then drawn on Briquetting on a suitable briquetting device. The, briquettes are supplied to a purge gas oven operating with steam as the purge agent, the Steam with a temperature of .loo to .f5o "enters the smoldering furnace. The distillates formed and the hydrogen produced are separated from the gas stream away. The distillation residue obtained in solid Fortn is first removed the caustic soda through a leaching process and subdues the leached briquettes, which now consist of carbonic acid 1a11 and finely divided charcoal. one Burning process. The calcium oxy-d obtained is used after fine grinding with the obtained Caustic soda for a new digestion of fossil wood.
