Verfahren zur Herstellung von Reformerfeed undProcess for the production of reformer feed and
Heizöl oder Diesel aus Kohle In dem Hauptpatent ... (Patentanmeldung P 34 28 783.3) wird ein neuartiges Verfahren zur Herstellung von Reformerfeed und HeizöL oder Diesel aus Kohle bei erhöhtem Druck und erhöhter Temperatur durch Sumpfphasenhydrierung mit angekoppelter Gasphasenhydrierung beschrieben, nach dem gemahlene Kohle ggf. unter Zusatz von katalytisch wirksamen Substanzen, mit einem Anmaischöl angemaischt und zunächst der Sumpfphasenhydrierung unterzogen und aus dem Abstrom der Sumpfphasenhydrierung nach Ausschleusen einer feststoffhaltigen Ruckstandsfraktion, ggf. nach Abtrennung einer als Anmaischöl dienenden Fraktion, nach Abkuhlen ein Produktstrom gewonnen wird, der zur Weiterverarbeitung der Gasphasenhydrierung unterworfen wird. Zwecks Senkung der in der Gasphasenhydrierung erforderlichen Betriebsdrucke auf etwa 50 bis 200 bar und Verminderung des Wasserstoffverbrauches wird der Gesamtwasserstoffbedarf von Sumpf- und Gasphasenhydrierung zunächst in die Gasphasenhydrierung als Frischwasserstoff, der weitgehend frei von den in einem Kreislaufgassystem der Kohlehydrierung enthaltenen Störkomponenten ist, eingesetzt und das hauptsächlich nicht umgesetzten Wasserstoff enthaltende Abgas wird in ein Kreislaufgas der Sumpfphasenhydrierung gegeben.Heating oil or diesel from coal In the main patent ... (patent application P 34 28 783.3) is a new process for the production of reformer feed and Heating oil or diesel from coal at increased pressure and temperature through sump phase hydrogenation described with coupled gas phase hydrogenation, after which ground coal may be with the addition of catalytically active substances, mashed with a mashing oil and first subjected to the sump phase hydrogenation and from the effluent to the sump phase hydrogenation after discharge of a residue fraction containing solids, if necessary after separation a fraction serving as mashing oil, a product stream obtained after cooling which is subjected to gas phase hydrogenation for further processing. For the purpose of Reduction of the operating pressures required in gas phase hydrogenation to around 50 The total hydrogen requirement is up to 200 bar and a reduction in the hydrogen consumption of sump and gas phase hydrogenation initially in the Gas phase hydrogenation as fresh hydrogen, which is largely free of those in a circulating gas system of the Carbohydrate-containing interfering components is used and that mainly Exhaust gas containing unreacted hydrogen is converted into a cycle gas of the sump phase hydrogenation given.
Gegenstand des Hauptpatents ist ferner die wichtige Feststellung, daß das in der Gasphasenhydrierung abgearbeitete Hydriergas ein fur die Sumpfphasenhydrierung in quantitativer als auch qualitativer Hinsicht geeignetes Hydriergas darstellt, welches insbesondere von den Verunreinigungen Kohlenmonoxid, Kohlendioxid, aber auch Schwefelwasserstoff und Ammoniak weitgehend frei ist.The subject of the main patent is also the important statement, that the hydrogenation gas processed in the gas phase hydrogenation is used for the sump phase hydrogenation represents a suitable hydrogenation gas in terms of both quantity and quality, which in particular from the impurities carbon monoxide, carbon dioxide, but also hydrogen sulfide and ammonia is largely free.
Die hierdurch zur Verfugung gestellte Wasserstoffmenge reicht aus, um den theoretisch notwendigen Wasserstoffverbrauch in der Sumpfphasenhydrierung zu decken.The amount of hydrogen made available in this way is sufficient around the theoretically necessary consumption of hydrogen in the sump phase hydrogenation cover up.
Aufgabe der Erfindung ist es, bei einem Verfahren nach dem Oberbegriff des Patentanspruches l die Schaltung der Gaskreisläufe so zu gestalten, daß eine Regelung der Temperatur im Gasphasereaktor möglich ist.The object of the invention is, in a method according to the preamble of claim l to design the circuit of the gas circuits so that a Regulation of the temperature in the gas phase reactor is possible.
Gemäß der Erfindung wird diese Aufgabe dadurch gelost, daß der Gesamtfrischwasserstrom aufgeteilt wird in eine Teilmenge, die dem Gasphasen-Feed vor Eintritt in die Gasphasenhydrierung zugefuhrt und die restliche Teilmenge, die als Quenchgas zur Temperaturregelung in die Gasphasenhydrierung gefuhrt wird.According to the invention, this object is achieved in that the total fresh water flow is divided into a partial amount that is fed to the gas phase before entering the gas phase hydrogenation fed in and the remaining part used as quench gas for temperature control is passed into the gas phase hydrogenation.
Gemäß Patentanspruch 2 wird das erfindungsgemäße Verfahren dadurch weiter ausgestaltet, daß der Gesamtdruck in der Gasphasenhydrierung niedriger ausgelegt ist als der Druck in der Sumpfphasenhydri erung.According to claim 2, the inventive method is thereby further configured that the total pressure in the gas phase hydrogenation is designed to be lower is than the pressure in the sump phase hydration.
Bei höheren Qualitätsanforderungen an die Produkte, die mit einem höheren Wasserstoffumsatz und damit größerer Exothermie in der Gasphasenhydrierung verbunden sind, kann gemäß den Patentanspruchen 3 und 4 a) zusätzlich aus dem Sumpfphasekreislauf Quenchgas in den Gasphasereaktor, b) zwecks Ruckfuhrung eines Teils des abgearbeiteten Hydriergases und Einspeisung als Quenchgas in den Gasphasereaktor bzw. Zufuhrung zum Gasphasefeed die Gasphase mit einem eigenen Gaskreislauf ausgestattet werden.In the case of higher quality requirements for the products with a higher hydrogen turnover and thus greater exothermicity in gas phase hydrogenation are connected, can according to claims 3 and 4 a) additionally from the sump phase cycle Quench gas in the gas phase reactor, b) for the purpose of returning part of the processed Hydrogen gas and feed as quench gas into the gas phase reactor or feed For the gas phase feed, the gas phase can be equipped with its own gas circuit.
Nach den Patentanspruchen 5 und 6 liegt der Druck in der Gasphase wenigstens um etwa 50 bar niedriger als der in der Sumpfphase angewandte Druck bzw. wird die Sumpfphase bei einem Druck von 100 bis 400 bar und die Gasphase bei einem Druck von 50 bis 200 bar betrieben.According to claims 5 and 6, the pressure is in the gas phase at least about 50 bar lower than the pressure applied in the sump phase or the bottom phase at a pressure of 100 to 400 bar and the gas phase at a Pressure operated from 50 to 200 bar.
Die Patentanspruche 7 bis II betreffen weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens wie sie in dem Hauptpatent erläutert sind.Claims 7 to II relate to further advantageous embodiments of the method according to the invention as explained in the main patent.
