Verfahren zur Brikettierung.
Bekanntlich wurde bereits versucht, verkleisterte Stärke und stärkehaltige Erzeugnisse als Bindemittel zum Brikettieren zu verwenden ; doch war die Bindung und Beständigkeit der auf diese Weise erzeugten Briketts eine derart mangelhafte, dass diese Verfahren fallen gelassen wurden.
Von diesen Verfahren abweichend und zum Unterschiede von diesen, soll nach vorliegender Erfindung als Bindemittel auf jede beliebige Weise gelöste verflüssigte Stärke gemengt mit den von ihrer Erzeugung herstammenden Kleber- und sonstigen Stoffen verwendet werden. Die gelöste Stärke ist in heissem Zustande flüssig, erstarrt l) ci erfolgter Abkühlung zu einer gelatinartigen Masse und bildet beim Trocknen eine hornartige Suh- stanz, welche nur wenig in heissem, überhaupt nicht in lialtem-Wasser löslich ist.
Das Bindemittel wird nun dem zu brikettierenden Material in heissem oder kaltem Zustande in entsprechender Menge beigemischt und indem es langsam erstarrt verbindet es die einzelnen Teilchen des zu brikettierendt'n Materials auf das Innigste miteinander,

bildet. Dieser Zusammenhalt wird durch Lagern und Trocknen wesentlich erhöht. Am zweckmässigsten hat sich die durch Hochdruck aufgeschlossene gelöste verflüssigte Stärke erwiesen und soll die Ausführung dieses Verfahrens mit Zuhilfenahme des auf diese Weise erzeugten Bindemittels an nachfolgendem Beispiele erläutert werden.
Die mit der entsprechenden Wassermenge versetzten stärkehaltigen Produkte werden in einem geschlossenen Gefässe so lange gedämpft und einem Hochdrucke ausgesetzt. bis sämtliche

anderes Gefäss ausgeblasen und in entsprechendem Verhältnisse entweder heiss oder abgekühlt, ohne oder mit Wasser verdünnt, dem zu brikettierenden Material beigemengt, das Gemisch wie üblich in Formen gepresst und eventuell getrocknet.
Bei manchen Kohlensorten kann ausserdem noch zur Erhöhung der Haltharkeit, sowie der Wetter-und Wasserbeständigkeit entweder dem Bindemittel direkt oder der zu brikettierenden Kohle eine dem Bedarfe entsprechende Menge rohes Erdöl beigemischt werden.

Briquetting process.
As is known, attempts have already been made to use gelatinized starch and products containing starch as binders for briquetting; however, the bond and durability of the briquettes produced in this way were so poor that these processes were abandoned.
Deviating from these processes and in order to differ from them, according to the present invention, liquefied starch dissolved in any desired manner should be used as a binder mixed with the adhesives and other substances derived from their production. The dissolved starch is liquid in the hot state, solidifies to a gelatinous mass after cooling and forms a horn-like suface on drying, which is only slightly soluble in hot water and not at all in cold water.
The binding agent is then added to the material to be briquetted in a hot or cold state in the appropriate amount and while it slowly solidifies it connects the individual particles of the material to be briquetted in the most intimate way,

forms. This cohesion is significantly increased through storage and drying. The dissolved liquefied starch that has been digested by high pressure has proven to be the most expedient and the execution of this process with the aid of the binder produced in this way will be explained in the following examples.
The starchy products mixed with the corresponding amount of water are steamed in a closed vessel for a long time and exposed to high pressure. until everyone

Blown out another vessel and either hot or cooled in the appropriate proportions, with or without water, added to the material to be briquetted, the mixture pressed into molds as usual and possibly dried.
In the case of some types of coal, in order to increase the durability and the weather and water resistance either directly to the binder or to the coal to be briquetted, an amount of crude oil corresponding to the requirement can be added.
Except for the briquetting of hard coal, brown coal, charcoal and coke, this binding
