Description
<Desc/Clms Page number 1>
Verfahren zur Gewinnung von Extrakten aus Kohle.
EMI1.1
<Desc/Clms Page number 2>
Es entstehen daher bei der erfindungsgemässen Arbeitsweise auch nicht die geringsten Mengen leichtflüchtiger Kohlenwasserstoffe, Benzine oder Öle, sondern es fallen, wie bei dem Verfahren des Stammpatentes, feste, schmelzbare Extrakte an, da lediglich intermediär anfallende dehydrierte Lösungsmittelanteile hydriert werden.
Das Verfahren nach der Erfindung kann auch unter Verwendung von Katalysatoren durchgeführt werden. Als besonders geeignet haben sich die Verbindungen des Molybdäns und der andern Elemente der Gruppe 6 a des periodischen Systems erwiesen.
Arbeitet man wie bei dem oben angegebenen Beispiel in Gegenwart von auf 200 Atm. komprimiertem Wasserstoff. aber sonst unter gleichen Bedingungen der Temperatur und der Verweilzeit wie beim Beispiel 1 des Hauptpatentes und verwendet man Molybdänsäure als Katalysator, so wird ebenfalls ein Tetrahydronaphthalinzerfall praktisch vermieden. Es findet ein Wasserstoffverbraueh von nur dz auf Kohle bezogen, statt. Die Extraktausbeute erhöht sieh auf 88%, während man beim Arbeiten olme Katalysator nur eine Ausbeute von 85% erzielt.
PATENT-ANSPRÜCHE :
1. Ausführungsform des Verfahrens des Stammpatentes Nr. 155810, dadurch gekennzeichnet, dass die Druckextraktion der Kohlen zwecks Aufrechterhaltung der Hydrierungsstufe der Lösungs-

wird, wobei die Wasserstoffmenge derart gering bemessen ist, dass eine Umwandlung der Kohle selbst oder der Extrakte in flüssige Öle. leicht siedende Benzine usw. nicht eintritt.

The procedure according to the invention therefore does not produce the slightest amounts of volatile hydrocarbons, gasoline or oils, but solid, meltable extracts, as in the process of the parent patent, since only intermediate dehydrogenated solvent components are hydrogenated.
The process according to the invention can also be carried out using catalysts. The compounds of molybdenum and the other elements of group 6a of the periodic table have proven to be particularly suitable.
If you work as in the example given above in the presence of to 200 atm. compressed hydrogen. but otherwise under the same conditions of temperature and residence time as in Example 1 of the main patent and if molybdic acid is used as the catalyst, tetrahydronaphthalene decomposition is also practically avoided. There is a hydrogen consumption of only double based on coal. The extract yield increases to 88%, while when working with no catalyst, only a yield of 85% is achieved.
PATENT CLAIMS:
1. Embodiment of the process of the parent patent No. 155810, characterized in that the pressure extraction of the coals for the purpose of maintaining the hydrogenation stage of the solution
EMI2.1
the amount of hydrogen is so small that a conversion of the coal itself or the extracts into liquid oils. low-boiling petrol etc. does not enter.
