Abstract
Die Erfindun betrifft ein Verfahren zur Herstellung eines gegenueber Wasser bestaendigen, brennbaren Agglomerats. Dazu werden ein feinteiliges, brennbares Material, ein organisches Bindemittel und ein Oxidationsmittel eingesetzt. Das Oxidationsmittel wird entweder mit dem brennbaren Material oder dem organischen Bindemittel oder mit dem einen oder anderen dieser Produkte oder deren Mischung gemischt. Die so erhaltene Mischung wird einer Agglomerierungsbehandlung unterzogen und das am Ende der Agglomerierungsbehandlung erhaltene Agglomerat einer Trocknung durch Erwaermen bzw. einer Ofentrocknung unterworfen.{Verfahren; Herstellung; brennbares Agglomerat; organisches Bindemittel; Oxidationsmittel; Trocknung; Ofentrocknung}The invention relates to a process for the preparation of a water-resistant combustible agglomerate. For this purpose, a finely divided, combustible material, an organic binder and an oxidizing agent are used. The oxidizing agent is mixed with either the combustible material or the organic binder or with one or other of these products or their mixture. The mixture thus obtained is subjected to agglomeration treatment, and the agglomerate obtained at the end of the agglomeration treatment is subjected to drying by heating or oven drying, respectively. manufacture; combustible agglomerate; organic binder; Oxidant; drying; Baking}

Das Gemisch wird durchfor a quarter of an hour with heating, the temperature rises to 9O 0 C. The final moisture measured using a moisture balance known as CENCO is then 8.5%.

Diese Kugeln werden hierauf in kaltes Wasser getaucht. Man stellt fest, daß sie sehr rasch auseinanderfallen. Nach einigen Minuten besitzt das Agglomerat überhaupt keine Kohäsion mehr.These balls are then immersed in cold water. One finds that they fall apart very quickly. After a few minutes, the agglomerate no longer has any cohesion at all.
Diese Ergebnisse zeigen, daß es möglich ist, allein unter Verwendung eines Bindemittels vom Stärke-Typ Feinkohle· Agglomerate zu bilden, die gute mechanische Eigenschaften aufweisen, jedoch gegenüber Wasser nicht beständig sind.These results show that it is possible to form fine coal · agglomerates using only a starch type binder, which have good mechanical properties but are not resistant to water.
und 2,5 kg native Getreidestärke. Man erhitzt das erhaltene Gemisch unter Durcharbeiten bis auf eine Temperatur von 50°C. Man versetzt dann mit 25g Ammoniumpersulfat, verdünnt in 2,51 Wasser. Man arbeitet hierauf das Gemisch eine Viertelstunde durch, indem man die Temperatur des Gemisches auf 9O0C bringt. Die letztendliche Feuchtigkeit beträgt dann 8%. Das Gemisch wird hierauf einer Agglomerierungsbehandlung durch Druckverdichtung unter den gleichen Bedingungen wie in Beispiel 1 unterzogen. Man erhält so Feinkohle-Kügelchen mit einer ausreichenden Kohä'iion in grünem Zustand, um einen Transport zu überstehen. Diese werden dann einer Wärmetrocknung während 2 Stunden bei einer Temperatur von 220°C unterzogen.and 2.5 kg of native corn starch. The resulting mixture is heated while working to a temperature of 50 ° C. It is then mixed with 25 g of ammonium persulfate, diluted in 2.51 of water. The mixture is then worked on for a quarter of an hour by bringing the temperature of the mixture to 9O 0 C. The final moisture is then 8%. The mixture is then subjected to agglomeration treatment by pressure compression under the same conditions as in Example 1. This gives fine coal pellets with a sufficient Kohä'iion green state to survive a transport. These are then subjected to heat drying for 2 hours at a temperature of 220 ° C.
