Description

Abscheidung von nicht brennbaren Stoffen aus gemahlener Kohle Die Erfindung bezieht sich auf Verfahren zur Abscheidung von Mineralstoffen und anderen nicht brennbaren Stoffen aus gemahlener Kohle. Solche Kohle, die weitgehend ohne Ascherückstand verbrennt, kann beispielsweise für sich oder im Gemisch mit anderen Brennstoffen als Kraftstoff für den Betrieb von Brennkraftmaschinen Verwendung finden.Separation of non-combustible materials from ground coal The Invention relates to methods of separating minerals and others non-combustible materials from ground coal. Such coal, largely without Ash residue burns, for example, on its own or in a mixture with others Find fuels as fuel for the operation of internal combustion engines.

Nach der Erfindung wird die gemahlene Kohle in Gegenwart von Säuren oder von Laugen einer LJltraschalll>ehandlung, z. 13. 1>e1 Frequenzen von ,5o k1 1z bis 20 11111z, unterworfen, um eine Gefügelockerung zu erzielen, durch welche ein praktisch vollst:indiges Herauslösen der aschebildenden Stoffe gewährleistet wird. Bei diesen handelt es sich in der Regel überwiegend um säurelösliche Substanzen. Jedoch kann unter Anwendung von Ultraschall auch nacheinander eine Behandlung in Säuren und in Laugen durchgeführt werden. Unter Umständen ist es zweckmäßig, daß die gemahlene Kohle nach der Ultraschallbehandlung noch einem Schlämmprozeß unterworfen wird.According to the invention, the ground coal is in the presence of acids or from caustic solutions from an ultrasound treatment, e.g. 13. 1> e1 frequencies of .5o k1 1z to 20 11111z, subjected to poultry loosening by which a practically complete: indigenous detachment of the ash-forming substances guaranteed will. As a rule, these are mainly acid-soluble substances. However, one treatment at a time can also be carried out using ultrasound Acids and alkalis. It may be useful that the ground coal is subjected to a slurrying process after the ultrasound treatment will.

Versuche haben ergeben, daß der Aschegehalt sich durch das vorgenannte Behandlungsverfahren mit Sicherheit auf weniger als o.co/o, in manchen Fällen aber auch noch weiter herabsetzen läßt. Auch bei gemahlener Braunkohle konnten diese Ergebnisse erreicht werden. Offenbar werden durch die Ultraschallbebandlung die in der Braunkohle vorhandenen fossilen Zellen zerstört.Experiments have shown that the ash content is determined by the aforementioned Treatment method with certainty to less than o.co/o, but in some cases can also be further reduced. These could also be used with ground lignite Results are achieved. Apparently the ultrasound treatment Destroys fossil cells present in lignite.
