Description
Die Erfindung betrifft die Flash-Pyrolyse von organischen Stoffen.The invention relates to the flash pyrolysis of organic substances.
Flash-Pyrolyse wird in Verbindung mit Biomasse zur Erzeugung eines ölhaltigen Zwischenproduktes (Slurry) eingesetzt, welches dann vorrangig zu Kraftstoff weiterverarbeitet werden kann (
Auch der Einsatz von organischen Abfallstoffen ist bekannt, wie z. B. von Reifen (Paten(Patente
Neben Pyrolysegas, -öl und -koks fallen dabei noch Wertstoffe wie Aktivkohle und Stahleinlagen an. Die Pyrolysetemperatur liegt in der Regel zwischen 500 und 600°C. Die Pyrolyse selbst findet in speziellen Reaktoren statt, die z. B. als zirkulierende Wirbelschichtanlage (

Verfahrens- und AnlagenbeschreibungProcess and plant description
Als Wärmeträgermedium wird eine ionische Flüssigkeit verwendet, die langzeitstabil in einem Temperaturbereich von ca. 200–600°C gegenüber den zum Einsatz kommenden Inputmaterialien ist.As the heat transfer medium, an ionic liquid is used which is long-term stable in a temperature range of about 200-600 ° C compared to the input materials used.
Die ionische Flüssigkeit kann gegebenenfalls einen Katalysator enthalten, der den Crackprozess verbessert.The ionic liquid may optionally contain a catalyst that improves the cracking process.
Die ionische Flüssigkeit (IF) ermöglicht eine gleichmäßige und maximale Wärmeübertragung auf die organische Einsatzmasse, die durch eine zweistufige Vorwärmung und Mischung gleichzeitig noch
- • optimal zerkleinert und vermischt sowie
- • entgast und entwässert wird.
- • optimally minced and mixed as well
- • degassed and dehydrated.
Im Gesamtprozess hat man damit ein gut handelbares pumpfähiges Medium mit guten Einstellmöglichkeiten der optimalen Prozessparameter, mit kurzen Wegen, keinem Verschleiß oder sonstigen Gefährdungen.In the overall process you have a good tradable pumpable medium with good adjustment options of the optimal process parameters, with short distances, no wear or other hazards.
An Hand der Bilder 1 bis 3 wird nachfolgend der Prozess beschrieben.The process is described below with reference to FIGS. 1 to 3.
Der Input wird in einem Shredder (
Bei Biomasse als Input kommt es hier infolge Steam-Explosion zur weiteren Desintegration des Materials, außerdem werden mit den Dampfwrasen Gase und Luft über die Entgasung (
Aus dem Zwischenhalter (
In der Hauptprozesspumpe (
Aus dem Entspannungs- und Trenngefäß (
Der heiße IF-Kreislauf versorgt den Heißmischer (
Die in dem organischen Einsatzmaterial enthaltene Asche wird kontinuierlich aus dem Entspannungs- und Trenngefäß (
Die Weiterverarbeitung der Pyrolysedämpfe (die hochreaktive Mikrokokspartikel enthalten) erfolgt je nach gewünschten Endprodukt.The further processing of the pyrolysis vapors (which contain highly reactive microcoolant particles) takes place depending on the desired end product.
Es werden 3 Hauptanwendungsfälle (Bild 1 bis 3) der Endprodukte dargestellt.3 main applications (Figures 1 to 3) of the final products are presented.
Im ersten Beispiel (Bild 1) werden die heißen Pyrolysedämpfe und das Synthesegas aus dem NT-Vergaser direkt in einem Blockheizkraftwerk (BHKW) mit modifiziertem Gasmotor verwendet.In the first example (Figure 1), the hot pyrolysis vapors and the synthesis gas from the NT carburetor are used directly in a combined heat and power plant (CHP) with a modified gas engine.
Im zweiten Beispiel (Bild 2) werden die heißen Pyrolysedämpfe zu einer Slurry aufbereitet. Die Slurry wird abgegeben – vorzugsweise zu einer FT-Kraftstoff-Verarbeitung. Das Rest-Pyrolysegas und das Synthesegas versorgen ein BHKW.In the second example (Figure 2), the hot pyrolysis vapors are treated to a slurry. The slurry is released - preferably for FT fuel processing. The residual pyrolysis gas and the synthesis gas supply a CHP.
Im dritten Beispiel (Bild 3) wird ergänzend zum vorhergehenden Beispiel noch eine niedrig siedende Fraktion Pyrolyseöl hergestellt, das als BHKW-Kraftstoff eingesetzt wird.In the third example (Figure 3), in addition to the previous example, a low-boiling fraction of pyrolysis oil is produced, which is used as CHP fuel.
