Abstract

(+21.9.90,6.12.90(2), 21.9.90,19.12.90, 6.3.91-DE-029880,038896/7, 029879,040672,107046). Macromolecules contg. organic -wastes are utilised by decomposing by warming to more than 150 deg.C, pref. under pressure or by shearing to liq. and gaseous components which can then be utilised. An appts. for carrying out the process comprises a melt vessel with a grate and a collecting vessel underneath for collecting the melt. It also has a pump and a means to treat the liq. and gaseous components further, pref. a mixing chamber.

Description

In der Patentanmeldung P 40 29 880.9 ist ein Verfahren zum Vergasen von Kunststoffen zur Erzeugung von Brenngasen be­ schrieben worden, bei dem Kunststoffe durch Behandlung bei erhöhter Temperatur in geeigneten Vorrichtungen soweit ver­ flüssigt werden, daß sie in Brennräume oder Reaktorräume eingedüst werden können.In the patent application P 40 29 880.9 a method for Gasification of plastics for the production of fuel gases in which plastics are treated by treatment ver increased temperature in suitable devices be liquid that they are in combustion chambers or reactor rooms can be injected.

Bei diesem Verfahren vergasen sehr viele Kunststoffe, wenn für die Verflüssigung ein Extruder verwendet wird und beim Austritt des verflüssigten Kunststoffes aus dem Extruder eine Druckentlastung erfolgt.In this process, many plastics gasify, if an extruder is used for the liquefaction and at Liquefied plastic emerges from the extruder a pressure relief takes place.

Für den Fall, daß bei gewissen Kunststoffen die Vergasung nach dem Extruder noch nicht ausreichend ist, werden die noch flüssigen Kunststoffe nicht in einen Brennraum oder Reaktor eingedüst, sondern in eine vorgeschaltete Verga­ sungskammer, die beheizt ist und in der die Vergasung er­ folgt.In the event that the gasification of certain plastics after the extruder is not sufficient, the still liquid plastics not in a combustion chamber or Reactor injected, but in an upstream Verga solution chamber, which is heated and in which the gasification follows.

Es hat sich ergeben, daß die verflüssigten Kunststoffe nicht nur zur Synthesegasherstellung, wie in Patentanmeldung P 40 17 089.9 beschrieben, oder als Brenngas, wie in Patent­ anmeldung P 40 29 880.9 beschrieben, sondern auch als Reduk­ tionsgas, z. B. für die Herstellung von Eisenschwamm, geeig­ net sind.It has been found that the liquefied plastics are not only for synthesis gas production, as in patent application P 40 17 089.9 described, or as fuel gas, as in patent registration P 40 29 880.9 described, but also as a Reduk tion gas, e.g. B. for the production of sponge iron are not.

Bei all diesen Verwendungen ist es sinnvoll, auf die be­ schriebene Art verflüssigte oder vergaste Kunststoffe nicht nur in extra dafür errichteten Anlagen zu verwenden, sondern sie auch in bestehende Anlagen zum teilweisen oder völligen Ersatz der dort verwendeten Reaktionsstoffe oder zusätzlich einzubringen. With all these uses, it makes sense to focus on the be written type does not liquefy or gasify plastics only to be used in specially constructed systems, but they also exist in existing systems for partial or complete Replacement of the reactants used there or in addition bring in.  

Eine weitere Möglichkeit der Verwendung der verflüssigten Kunststoffe besteht darin, daß aus verflüssigten Kunststof­ fen Granalien oder durch Versprühen Pulver hergestellt wer­ den, die als leicht dosierfähige Vorstoffe zur Erzeugung von Synthesegas und/oder andere verwertbare Gase oder als Brenn­ stoff oder als Reduktionsmittel verwendet werden können.Another way of using the liquefied Plastics is that of liquefied plastics fen granules or by spraying powder the, which as easy to dose precursors for the production of Synthesis gas and / or other usable gases or as fuel substance or can be used as a reducing agent.

Dafür ist die Eigenschaft der in Frage kommenden Kunststoffe wichtig, praktisch rückstandsfrei bei erhöhter Temperatur zu vergasen. Bei einer Körnung von 2 mm Durchmesser erfolgt die Vergasung bei 1000°C in weniger als 0,5 Sekunden.This is the property of the plastics in question important, practically residue-free at elevated temperature gasify. With a grain size of 2 mm in diameter Gasification at 1000 ° C in less than 0.5 seconds.
