Beschreibungdescription
Die Erfindung betrifft ein Verfahren zur Erzeugung von Permanentgasen und Ruß aus Abfallstoffen, wobei die Abfallstoffe bei" mäßig hoher Temperatur in einem Schwelreaktor verschwelt und die dabei entstehenden Schwelgase nachfolgend bei erhöhter Temperatur in einem Crackreaktor gecrackt werden. Die Erfindung betrifft ferner einen Crackreaktor zur Durchführung dieses Verfahrens.The invention relates to a method for generating permanent gases and soot from waste materials, the waste materials carbonized at "moderately high temperature in a carbonization reactor and the resulting carbonization gases subsequently be cracked at elevated temperature in a cracking reactor. The invention also relates to a cracking reactor for Implementation of this procedure.
Bei der Abfallpyrolyse erfolgt die Verschwelung der Abfallstoffe, unter anderem zur Vermeidung von Werkstoffproblernen bei den aufgrund der zu verarbeitenden Abfallmengen notwendigerweise großen Reaktortrommeln oder Reaktorrohren, bei mäßig hohen Temperaturen von ca. 800 K oder weniger. Das dabei entstehende kohlenwasserstoffreiche Schwelgas ist hinsichtlich seiner Weiterverwendung etwa als Brenngas oder als Kondensat nicht besonders wertvoll, so daß eine Aufbereitung geboten ist. Diese kann im Hinblick auf die Gewinnung eines hochwertigen öligen Kondensats in einer Zyklisierung bzw. Aromatisierung der vorhcndenden Kohlenwasserstoffe bestehen. Bei wasserhaltigen oder bei der Pyrolyse wasserabspaltenden Ausgangsmaterialien führt dieses Verfahren jedoch zu Umweltschutzproblemen, da hierbei Abwasser entstehen, die mit biologisch nicht abbaubaren organischen Stoffen befrachtet sind.In the case of waste pyrolysis, the waste materials are charred, Among other things, to avoid material problems due to the amount of waste to be processed necessarily large reactor drums or reactor tubes, at moderately high temperatures of approx. 800 K or less. The resulting carbon-rich carbonization gas is in terms of its further use, for example, as fuel gas or as condensate is not particularly valuable, so that processing is required. This can be done in cyclization with a view to obtaining a high-quality oily condensate or aromatization of the existing hydrocarbons exist. With water-based or with pyrolysis However, this process leads to environmental problems with dehydrating starting materials, since it is wastewater that are loaded with non-biodegradable organic substances.
Bei der Pyrolyse wasserhaltiger oder wasserabspaltender Stoffe empfiehlt sich daher der umgekehrte Weg der Crackung des Schwelgases zu Permanentgasen und Ruß. Es ist ein Verfahren bekannt (DE-OS 24 32 504), nach welchem die Crackung des bei der Pyrolyse entstandenen Schwelgases durch Leiten desselben über ein glühendes Koksbett entsprechender Temperatur erfolgt. Nachteilig an diesem VerfahrenFor the pyrolysis of water-containing or water-releasing substances, the opposite approach is therefore recommended Cracking of the carbonization gas to permanent gases and soot. There is a method known (DE-OS 24 32 504), according to which the Cracking of the carbonization gas produced during the pyrolysis by passing it over a glowing bed of coke Temperature takes place. Disadvantage of this process

daß eine Temperatursteuerung, die durch Steuerung der zugeführten Frischluftmenge in Anpassung an die jeweiligen Brenneigenschaften des Koks erfolgen muß, schwierig ist. Hinzu kommt, daß ein Teil des Schwelgases bei diesem Verfahren über dein Koksbett verbrennt und außerdem das verbleibende aufbereitete Schwelgas durch den Stickstoff aus der Luft "verdünnt" ist.that a temperature control by controlling the amount of fresh air supplied in adaptation to the respective Burning properties of the coke must be done is difficult. In addition, part of the carbonization gas in this process burns over your coke bed and also removes the remaining processed carbonization gas through the nitrogen the air is "diluted".
Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, nach welchem die Einhaltung einer konstanten Temperatur für die Crackung einfach ist.The object of the invention is therefore to provide a method according to which a constant temperature is maintained for cracking is easy.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Erwärmung des Crackreaktors auf Cracktemperatur durch elektrische Widerstandsbeheizung erfolgt. Dieses Verfahren hat ferner den Vorteil, daß es ohne Zutritt von Fremdgasen durchgeführt werden kann, so daß sich eine unerwünschte Versetzung des aufzubereitenden bzw. aufbereiteten Schwelgases mit diesen vermeiden läßt. Darüber hinaus ermöglicht die elektrische Widerstandsbeheizung eine exakte Temperaturkontrolle bei guter Steuer- bzw. Regelbarkeit, wie sich überhaupt die für die Crackung erforderlichen hohen Temperaturen von etwa 1200 bis 1500 K ohne Schwierigkeiten erreichen lassen.According to the invention, this object is achieved in that the cracking reactor is heated to cracking temperature takes place by electrical resistance heating. This method also has the advantage that it does not require the entry of foreign gases can be carried out, so that there is an undesirable shift in the carbonization gas to be processed or processed with these can be avoided. In addition, the electrical resistance heating enables precise temperature control with good controllability, as well as the high temperatures required for cracking from about 1200 to 1500 K can be achieved without difficulty.
Vorzugsweise wird die für die Widerstandsbeheizung notwendige elektrische Energie aus dem Pyrolyseprozeß selbst gewonnen, wobei sie insbesondere durch Verbrennung der gecrackten Schwelgase in einem einen elektrischen Generator betreibenden Gasmotor erzeugt wird. Diese Verfahrensführung ist besonders vorteilhaft, v/eil sie energieautark und wegen der Gleichzeitigkeit von Energieerzeugung und Energiebedarf von Energiespeicherungsproblomen unbelastet ist.The electrical energy required for resistance heating is preferably obtained from the pyrolysis process itself obtained, in particular by burning the cracked carbonization gases in an electrical generator operating gas engine is generated. This procedure is particularly advantageous because it is energy self-sufficient and because of the simultaneity of energy generation and energy demand is unencumbered by energy storage problems.
Abfallstoffe, für die sich dieses Verfahren bevorzugt anbietet, sind alle wasserhaltigen oder bei der PyrolyseWaste materials for which this method is preferred offers are all hydrous or pyrolytic

Bevorzugt ist er als Strömungsrohr ausgebildet und sind als Widerstandsbeheizung im Inneren über den Strömungsquerschnitt verteilte, in Strömungsrichtung verlaufende widerstandsbeheizte Stäbe vorgesehen. Durch die Verteilung der Stäbe über den Querschnitt i?t es möglich, eine große Heizfläche, die nicht nur am Rand des Reaktors liegt, zu schaffen, wodurch das zu crackende Schwelgas gleichmäßig auf die erforderliche Temperatur gebracht werden kann. Vorzugsweise sind die Stäbe Keramikstäbe, weil diese eine hohe Temperaturfestigkeit aufweisen und gegen die aufzubereitenden und aufbereiteten Gase resistent sind.This object is achieved by a cracking reactor in which an electrical to generate the cracking temperature Resistance heating is provided. It is preferably designed as a flow tube and is used as a resistance heater Resistance-heated rods distributed inside over the flow cross-section and running in the direction of flow intended. By distributing the rods over the cross-section, it is possible to have a large heating surface that is not only on the edge of the reactor is to create, whereby the carbonization gas to be cracked evenly to the required level Temperature can be brought. The rods are preferably ceramic rods because they have a high temperature resistance have and against the to be processed and processed Gases are resistant.
