Description
Verfahren zur Herstellung von Ligninbriketten Es ist bekannt, kohlenstoffhaltige Stoffe und Abfälle mit oder ohne Verwendung von Bindemitteln zu brikettieren und anschließend zu verkoken, ohne daß hierbei die Brikette zerfallen. Man hat auch bereits Brennstoffbrikette aus den unlöslichen Rückständen von der Behandlung von Holz mit verdünnten Säuren hergestellt. Da dieser Rückstand nur zum Teil aus Lignin und oft zur Hälfte aus Umwandlungsprodukten der Cellulose besteht, war für dieses Produkt sowohl der Gedanke der Verwendung für Brennstoffzwecke als auch der Erzielung einer handlichen Form durch Brikettierung ohne weiteres gegeben.Process for the production of lignin briquettes It is known, carbonaceous Briquetting substances and waste with or without the use of binders and then to coke without disintegrating the briquette. One also has already fuel briquette from the insoluble residues from the treatment of Wood made with dilute acids. Because this residue is only partly made up of lignin and often half consists of conversion products of cellulose, was for this Product both the idea of using it for fuel purposes and of obtaining it easily given a handy shape by briquetting.
Vorliegende Erfindung bezweckt durch Anwendung der Brikettierungsmethode mit anschließender Verkokung zu einem Kohlematerial von besonderer Gleichmäßigkeit zu gelangen, wobei ebenfalls der unlösliche Rückstand der Verzuckerung von Holz durch Säurehydrolyse als Rohstoff benutzt wird. Dieser Rückstand stellt im Unterschied von der erwähnten, bei der Behandlung von Holz entstehenden Holzverzuckerung mit verdünnten Säuren reines Lignin dar, dessen wesentlich höherer Kohlenstoffgehalt in den Brikettierungsprodukten sehr wertvoll ist und die Verkokungsarbeit vereinfacht. Dieser. durch konzentrierte Säuren aus Holz gewonnene Rückstand läßt sich überraschenderweise ebenfalls ohne Zusatz von Bindemitteln, gegebenenfalls unter Wärmeanwendung, brikettieren. Die Brikette zerfallen nicht beim Verkoken, so daß nach der Verkokung ei n# Brikett von sehr großer Gleichförmigkeit erhalten wird, das nahezu frei von Mineralbestandteilen ist.The present invention aims by using the briquetting method with subsequent coking to a carbon material of particular uniformity to arrive, likewise the insoluble residue of the saccharification of wood is used as a raw material by acid hydrolysis. This residue makes the difference from the mentioned, occurring during the treatment of wood with wood saccharification diluted acids are pure lignin with a much higher carbon content is very valuable in the briquetting products and simplifies the coking work. This. Surprisingly, residue obtained from wood by concentrated acids can be obtained Briquetting also without the addition of binders, if necessary with the application of heat. The briquettes do not disintegrate during coking, so that after coking a briquette of very great uniformity is obtained, which is almost free of mineral constituents is.
Die unmittelbare Nutzbarmachung der Ligninrückstände durch trockene Destillation scheiterte bisher daran, daß sie an den Retortenwänden dauernd Krusten bilden, die im Laufe der Zeit die Ausbringung des Fertigprodukts erschweren. Führt man dagegen jene Rückstände vor der Verkokung in Brikettform über, so wird die lästige Erscheinung der Krustenbildung und des Anbackens an den Retortenwänden vermieden. Besonders geeignet ist die Brikettform mit runden Begrenzungsflächen, z. B. Eiform, wodurch die Berührungsfläche zwischen Brikett und Retortenwand verringert wird.The immediate utilization of the lignin residues through dry So far, distillation has failed because it has permanent crusts on the retort walls which over time make it more difficult to apply the finished product. Leads On the other hand, if you put those residues in briquette form before coking, the annoying thing becomes The appearance of crust formation and caking on the retort walls is avoided. The briquette form with round boundary surfaces, e.g. B. Egg shape, whereby the contact area between the briquette and the retort wall is reduced.
Die überraschende Erscheinung, daß die Brikette bei der Verkokung nicht zerfallen, kann dadurch unterstützt werden, daß die spezifische Destillationsfläche möglichst klein gehalten wird. Da die Verkokungswärme vorzugsweise durch die Leitung an den Berührungsstellen zwischen Retortenwand und Destillationsgut zugeführt wird, läßt sich die zur Erhaltung der Form beim Verkoken vorteilhafte allmähliche Wärmezufuhr dadurch erzielen, daß man jene Wärmedurchgangsfläche so klein wie möglich hält.The surprising appearance that the briquette when coking do not disintegrate, can be supported by the fact that the specific distillation area is kept as small as possible. As the heat of coking is preferably carried out through the pipe is supplied at the points of contact between the retort wall and the material to be distilled, The gradual supply of heat, which is advantageous for maintaining the shape during coking, can be used achieve by keeping that heat transfer area as small as possible.
Die Verkokungstemperatur beträgt etwa 400 °/o.The coking temperature is about 400%.
Die verkokten Ligninbrikette eignen sich beispielsweise zum Ersatz von Holzkohlen, weil sie beim Verbrennen an der Luft restlos verglimmen, oder als Füllung für Spezialöfen und zur Regulierung des Kohlendioxydgehaltes der Luft, z. B. in Gewächshäusern.The coked lignin briquettes are suitable, for example, as a substitute of charcoal, because they are completely in the air when burned fade away, or as a filling for special ovens and to regulate the carbon dioxide content of the Air, e.g. B. in greenhouses.
