Description

Gewinnung hochaktiver Kohle Bei. der Berginisierung von Kohle (Gewinnung von flüssigen organischen Verbindungen aus Kohle durch Erhitzen unter hohem Wasserstoffdruck) hvnterbleibt ein gewisser Teil der organischen Substanz als unaufgeschlossene Restkohle, deren Menge je nach der Kohlenqualität verschieden ist und u. U. bis zu 2o % der ursprünglichen Kohlensubstanz betragen kann. Diese Restkohle fällt bei der normalen Aufarbeitung der Kohlebergimprodukte durch Destillation, Filtration und Extraktion zusammen mit dar Kohlenasche und mit etwa benutzten anorganischen Zusätzen, z. B. Gasreinigungsmasse, als trokkeries schwarzes Pulver .an. Der Aschengehalt dieses Pulvers kann bis zu 5o ofo und mehr b'e'tragen, wodurch es als solches ziemlich wertlos ist. Nachteilig ist außer dein hohen Gehalt an Asche der in dieser angereicherte, aus der Rohkohle stammende Schwefel.Extraction of highly active coal. the mining of coal (extraction of liquid organic compounds from coal by heating under high hydrogen pressure) a certain part of the organic matter remains as undigested residual coal, the amount of which differs depending on the coal quality and possibly up to 20% of the original carbon substance can be. This residual coal falls with the normal one Processing of the coal mountain products by distillation, filtration and extraction together with the coal ash and with any inorganic additives used, e.g. B. Gas cleaning compound, as dry black powder .an. The ash content of this Powder can carry up to 50 ofo and more, which makes it pretty good as such is worthless. In addition to the high content of ash, the disadvantage is the enriched in this, sulfur from the raw coal.

Es wurde gefunden, daß aus diesem an sich geringwertigen Abfallprodukt der Kohleberginisierung hochaktive Kohle gewonnen werden kann, wenn man dieses Pulver mit Säuren behandelt. Beispielsweise wurde ein. solches Pulver in heißer Salzsäure längere Zeit gekocht und sodann filtriert. Der Filterrückstand wurde mit heißem Wasser ausgewaschen, getrocknet und schließlich in einer Schwelretorte bei 5oo° geglüht. Das dabei erhaltene Produkt besitzt eia ausgezeichnetes Absorptionsvermögen für Gase, wie Benzol, Ammoniak, Schwefelwasserstoff, und ist in dieser Beziehung den bekannten aktiven Kohlen gegenüber vollkommen gleichwertig. Eis ist auch für alle anderen Verwendungsmöglichkeiten ,aktiver Kohlen brauchbar, z. B. zum Raffinieren von Öl.It has been found that from this per se inferior waste product The coal mining highly active coal can be obtained using this powder treated with acids. For example, a. such powder in hot hydrochloric acid boiled for a long time and then filtered. The filter residue was with hot Washed out water, dried and finally in a smoldering retort at 500 ° annealed. The product obtained thereby has an excellent absorption capacity for gases such as benzene, ammonia, hydrogen sulfide, and is in this regard Completely equivalent to the known active coals. Ice cream is for too all other possible uses, active coals can be used, e.g. B. for refining of oil.

Wurden bei denn dieses Abfallprodukt liefernden Berginisierungsprozeß wertvollere anorganische Zusätze benutzt, deren Wiedergewinmiung erwünscht ist, so besteht hierzu nach denn vorliegenden Verfahren die Möglichkeit. Die Zusatzmassen werden durch die Behandlung mit Säure gelöst und aus den erhaltenen Lösungen in bekannter Weise abgeschieden. Hierfür können der bei der Säurebehandlung entweichende Schwefelwasserstoff sowie das beim Berginisierungsprozeß gebildete Ammoniak mitverwendet werden.Were in the Berginization process that supplies this waste product uses more valuable inorganic additives, the recovery of which is desirable, so there is the possibility of doing so according to the present procedure. The additional masses are dissolved by the treatment with acid and from the solutions obtained in deposited in a known manner. For this, the escaping during the acid treatment can be used Hydrogen sulfide and the ammonia formed during the Berginization process are also used will.
