Preparation of hydrogen-rich synthesis gas (I) from biogenous materials and other carbon-containing compounds by means of water vapor gasification (steam reforming) in a fluidized bed reactor (C1, hybrid reactor) comprises providing heat transmission elements (W1) into the fluidized bed, which allows a certain heat introduction in into the reactor, without by the heating of the heat transmission elements possibly developing smoke gases into contact with the materials used in the reactor steps (allotherm warm introduction); and providing oxygen into the fluidized bed reactor, where the heat release in the reactor is made possible by partial oxidation of the used materials .

Description

Es ist bekannt, biogene Stoffe (Biomasse gemäß EEG, Biomüll, Klärschlamm/Gülle tierische Abfälle) und sonstige kohlenstoffhaltige Verbindungen (im folgenden Einsatzstoff genannt) mit unterschiedlichen Verfahren zu vergasen. Als wesentliche Verfahren sind hier sogenannte autotherme (direkt beheizte) und allotherme (indirekt beheizte) Vergaser bekannt und technisch ausgeführt.It is known, biogenic substances (biomass according to EEG, organic waste, sewage sludge / manure animal waste) and other carbonaceous compounds (hereinafter feedstock) called) to gasify with different methods. As essential Procedures are here called autothermal (directly heated) and Allotherme (indirectly heated) carburetor known and engineered.

In autothermen Systemen wird die für die Vergasung erforderliche Reaktionswärme über exotherme Reaktionen (partielle Oxidation) der Einsatzstoffe mit eingebrachten Sauerstoff bereitgestellt. Aufgrund der bekannten Teerproblematik und des geringen Heizwertes des erzeugten Gases sind diese Systeme jedoch nur sehr eingeschränkt für die Erzeugung von wasserstoffreichen Synthesegas geeignet.In autothermal systems will be the for the gasification required heat of reaction via exothermic reactions (partial Oxidation) of the feedstocks provided with oxygen introduced. by virtue of the well-known tar problem and the low calorific value of the generated Gases, however, these systems are very limited for the generation suitable for hydrogen-rich synthesis gas.

Allotherme Systeme mit Wasserdampfvergasung im Wirbelschichtreaktor hingegen liefern mittel- bis hochkalorische Gase mit hohem Wasserstoffanteil. Dieses aus dem Einsatzstoff erzeugte Gas entspricht aufgrund der wesentlichen Komponenten (H2, CH4, CO, CO2) den in der chemischen und petrochemischen Industrie bekannten Synthesegasen.allothermal By contrast, systems with steam gasification in the fluidized bed reactor supply medium to high calorific gases with high hydrogen content. This generated from the feed gas corresponds due to the essential components (H2, CH4, CO, CO2) in the chemical and petrochemical industry known synthesis gases.

In der technischen Anwendung der allothermen Systeme zeigen sich jedoch Schwierigkeiten die Reaktionswärme über in den Reaktor eingebrachte Heizflächen bereitzustellen. Aufgrund des Wärmeübertragungsverhaltens der bekannten Beheizungssysteme ergeben sich Beschränkungen bei der technischen Realisierbarkeit, da das erforderliche Verhältnis von Reaktorquerschnitt (Wirbelschicht) zu erforderlichen Heizflächen bei den derzeit bekannten Beheizungssysteme einer sinnvollen technischen Lösung entgegensteht.In However, the technical application of the allothermal systems is evident Difficulties the heat of reaction in the Reactor introduced heating surfaces provide. Due to the heat transfer behavior The known heating systems are subject to restrictions in the technical feasibility, since the required ratio of Reactor cross section (fluidized bed) to required heating surfaces at the currently known heating systems of a meaningful technical solution opposes.

Der in den Patentansprüchen 1–5 angegebenen Erfindung liegt die Aufgabe zugrunde die Vorteile der beiden allothermen und autothermen Verfahrensweise zur Vergasung von biogenen Einsatzstoffen zu verbinden und gleichzeitig die Nachteile der genannten Verfahren zu vermeiden.Of the in the claims 1-5 specified Invention is the object of the advantages of the two allothermal and autothermal procedure for the gasification of biogenic feedstocks to connect and at the same time the disadvantages of the said methods to avoid.

Erfindungsgemäß wird die vorstehende Aufgabe gelöst durch die Anwendung eines Verfahrens zur Erzeugung von Synthesegas mit den Merkmalen der Patentansprüche 1, 2 und 3.According to the invention solved the above task by the application of a process for the production of synthesis gas with the features of claims 1, 2 and 3.

Demnach ist ein Verfahren zur Erzeugung von Synthesegas dadurch gekennzeichnet, dass einerseits Wärmeübertragungselemente in einen Wirbelschichtreaktor eingebaut sind, wobei hier auf Systeme zurückgegriffen werden kann, die am freien Markt in technisch ausgereifter Ausführung zur Verfügung stehen.Therefore a process for the production of synthesis gas is characterized on the one hand heat transfer elements are incorporated in a fluidized bed reactor, in which case systems resorted can be used on the open market in technically mature execution disposal stand.

Je nach Effizienz der einzelnen Systeme und unter Berücksichtigung der möglichen in den Wirbelschichtreaktor einsetzbaren (sinvoll baubaren) Heizflächen ergibt sich eine in den Reaktor einzubringende Wärmeleistung, die die für die endotherme Vergasungsreaktionen erforderliche Reaktionswärme zu einem gewissen Teil abdeckt. Am Markt verfügbare Standardsysteme (Mantelstrahlbrenner, Lavalbrenner, etc) erlauben eine Einbringung der benötigten Reaktionswärme von mehr als 80%.ever according to the efficiency of each system and taking into account the possible can be used in the fluidized bed reactor (sinvoll baubaren) heating surfaces itself a to be introduced into the reactor heat output, that for the endothermic Gasification reactions required reaction heat to a certain extent covers. Standard systems available on the market (Mantelstrahlbrenner, Lavalbrenner, etc) allow a contribution the required heat of reaction of more than 80%.

Der für die endotherme Reaktion bei Vollast erforderliche Anteil an Wärmeenergie wird erfindungsgemäß durch das Einbringen von Sauerstoff in den Reaktor erreicht. Der zusammen mit dem heißen Fluidisierungsdampf eingebrachte Sauerstoff führt zur partiellen Oxidation der Kohlenstoffanteile der Einsatzstoffe bei einer Betriebstemperatur von ca. 780–830°Cel. Diese exotherme Reaktion setzt nun die für die Gesamtreaktionen des gesamten Einsatztstoffstromes erforderliche Wärmemenge frei, sodaß als Reaktionsprodukt ein wasserstoffreiches Synthesegas entsteht.Of the for the endothermic reaction at full load required fraction of heat energy is inventively achieved the introduction of oxygen into the reactor. The together with the hot fluidizing vapor introduced oxygen leads to Partial oxidation of the carbon content of the starting materials at an operating temperature of about 780-830 ° Cel. This exothermic reaction now sets the for the overall reactions of the entire feedstock stream required heat free, so as Reaction product a hydrogen-rich synthesis gas is formed.

Durch Veränderung der zugegebenen Sauerstoffmenge ist im Betriebspunkt zudem eine einfache Regelungsmöglichkeit des Reaktors gegeben.By change the amount of oxygen added is also one at the operating point easy control option given to the reactor.

Desweiteren ist erkannt, daß eine erfindungsgemäße Einbringung gemäß Anspruch 3 von Sauerstoff in den Entspannungsraum des Wirbelschichtreaktors eine weitere Verbesserung der Effizienz zur Folge hat, da im Entspannungsraum schwebende Kohlenstoffpartikel, die durch ein hohes spezifisches Oberflächenverhältnis gekennzeichnet sind, schlagartig mit dem eingebrachten Sauerstoff reagieren und einerseits Wärmeenergie bereitstellen und andererseits die Kohlenstoffkonversion des Gesamtsystems deutlich verbessern.Furthermore is recognized that a inventive introduction according to claim 3 of oxygen in the expansion space of the fluidized bed reactor a further improvement in efficiency results in the relaxation room floating carbon particles, which are characterized by a high specific Surface ratio marked are abruptly reacting with the oxygen introduced and on the one hand heat energy and on the other hand the carbon conversion of the whole system improve significantly.

Erreichte Vorteile:Achieved benefits:

Die mit der beschriebenen Erfindung erzielten Vorteile bei der Verwendung des beschriebenen Verfahrens bestehen insbesondere darin, dass:

  • • Aufgrund der Kopplung einer allothermen Wärmeeinbringung mit der Freisetzung von Wärmeenergie durch partielle Oxidation der Einsatzstoffe einfache, technisch bewährte Beheizungssysteme verwendet werden können, was eine hohe Zuverlässigkeit des Gesamtsystems bedeutet.
  • • Die Wärmezufuhr durch partielle Oxidation sowohl mit reinem Sauerstoff als auch mit Luftsauerstoff erzielt werden kann. Insbesondere bei der Verwendung von Luftsauerstoff lassen sich damit technisch einfache und kostengünstige Apparate zur Gaserzeugung herstellen.
  • • Aufgrund der Einbringung von Sauerstoff zusammen mit dem Fluidisierungsdampfeine optimale Vermischung und Reaktion des Sauerstoffs mit dem Kohlenstoff der Einsatzstoffe bei den Betriebstemperaturen von 780–830°Cel erfolgt, was eine direkte Freisetzung der exothermen Wärme aus der partiellen Oxidation in die Wirbelschicht ermöglicht. Aufgrund der intensiven Durchmischung in der Wirbelschicht bildet sich eine homogen Temperaturverteilung in der Wirbelschicht wodurch Störreaktionen minimiert werden.
  • • Aufgrund der Umsetzung des Fluidisierungsdampfes bei den Betriebstemperaturen von ca. 780–830°Cel und aufgrund der auftretenden Wassergas Reaktion eine Wasserstoffatmosphäre mit resultierenden geringen Partialdrücken für schwere Kohlenwasserstoffverbindungen (Teere) ausgebildet wird, die (auch aufgrund von damit induzierten Zerfällen von langkettigen Kohlenwasserstoffen) insgesamt zu einer reduzierten Teerbildung im System führt.
  • • Aufgrund der Möglichkeit von Sauerstoffeinblasung im Expansionsraum Teere weiterhin zerstört und die Kohlenstoffkonversion insgesamt erhöht wird.

  • • Due to the coupling of an allothermal heat input with the release of heat energy by partial oxidation of the feedstock simple, technically proven heating systems can be used, which means a high reliability of the entire system.
  • • The heat supply can be achieved by partial oxidation with both pure oxygen and atmospheric oxygen. Especially with the use of atmospheric oxygen can be so produce technically simple and cost-effective apparatus for generating gas.
  • Due to the introduction of oxygen along with the fluidization vapor, optimum mixing and reaction of the oxygen with the carbon of the feeds occurs at the operating temperatures of 780-830 ° Cel, allowing direct release of the exothermic heat from the partial oxidation to the fluidized bed. Due to the intensive mixing in the fluidized bed, a homogeneous temperature distribution is formed in the fluidized bed, whereby interference reactions are minimized.
  • Due to the implementation of the fluidization steam at the operating temperatures of about 780-830 ° C and due to the occurring water gas reaction, a hydrogen atmosphere with resulting low partial pressures is formed for heavy hydrocarbon compounds (tars) which (also due to the induced decay of long-chain hydrocarbons) leads overall to a reduced tar formation in the system.
  • • Due to the possibility of oxygen blowing in the expansion chamber tars continue to be destroyed and the overall carbon conversion is increased.
