Verfahren zur Verwendung von Pyrolyseöl aus einerMethod of using pyrolysis oil from a
Altgummipyrolyse,insbesondere von Altreifen beanspruchte Triorität Ausstellungspriorität im Wettbewerb "Jugend forscht '77" ( Mannheim 14.2.77 stuttgart 22.3.77 Berlin 1. 5.77 Verfahren zur Verwendung von Fyrolyseöl aus einer dltgummipyrolyse,insbesondere von altreifen.Pyrolysis of used rubber, especially of used tires, is a priority Exhibition priority in the competition "Jugend forscht '77" (Mannheim 02/14/77 stuttgart 22.3.77 Berlin, 1. 5.77 Method of using fyrolysis oil from dlt rubber pyrolysis, especially of old tires.
gegenstand der Srfindung ist ein Verfahren zum wesentlich wirtschaftlicheren Einsatz von Fyrolyseöl aus Altgummi nach Abtrennung der wässrigen Phase.The subject of the invention is a process for the much more economical Use of fyrolysis oil from old rubber after separation of the aqueous phase.
Nach dem Stand der Technik ist bisher nur vorgeschlagen worden, ryrolyseöl als Rohölersatz,als Treibstoff oder zu Heizzwecken zu verwenden. - Demgegenüber stellt sich das erfindungsgemäße Verfahren die Aufgabe'das bei der Altgummipyrolyse anfallende Tyrolyseöl,unter Berücksichtigung seines Aromatenreichtums, nach einer bestimmten Fraktionierung neuen Verwendungszwecken zuzuführen.According to the prior art, only tyrolysis oil has been proposed so far to use as a crude oil substitute, as fuel or for heating purposes. - On the other hand The process according to the invention sets itself the task of the waste rubber pyrolysis accruing tyrolysis oil, taking into account its richness in aromatics, after a new uses for certain fractionation.
Die Lösung der Aufgabe besteht darin,daß das Gesamtöl in einzelne Fraktionen aufgespalten wird und diese dann getrennt aufgearbeitet werden.The solution to the problem is that the total oil in individual Fractions is split up and these are then worked up separately.
Die Zerlegung des uesamtöles erfolgt vorzugsweise in Fraktionen 1. Fraktion bis ca. 200 °C Diese Fraktion kann zur lösung von Kunststoffen vorzugsweise Elastomeren z.B. Solpren,Interlan,Buna usw. verwendet werden und diese nach Zugabe von Schwefel und/oder anderen geeigneten Zusatzmitteln und Beschleunigern in bekannter eise vulkanisiert werden.The uesam oil is preferably broken down into fractions 1. Fraction up to approx. 200 ° C This fraction can preferably be used to dissolve plastics Elastomers e.g. Solpren, Interlan, Buna etc. can be used and these after addition of sulfur and / or other suitable additives and accelerators in known be vulcanized in ice.
Auch eine Gewinnung von Benzol,Toluol,Xylol usw. ist möglich ; ebenso eine Verwendung als Harrohstoff analog dem Steinkohlenteer.It is also possible to obtain benzene, toluene, xylene, etc.; as well a use as urea similar to coal tar.
2. Fraktion über ca. 2CC °C Die Verwendung dieser Fraktion bringt für die Verarbeitung bituminöser Massen wie z.B. in Dach-und Dichtungsbahnen,Schall-und Wärmedämmplatten,dauerelastischen Fugenverguß-und Spachtelmassen,Bitumen-Kunstatoffbahnen,Kunststoffbahnen usw. entscheidende,bisher nicht bekannte Vorteile.2. Fraction above about 2CC ° C The use of this fraction brings for the processing of bituminous masses such as in roofing and waterproofing membranes, sound and Thermal insulation boards, permanently elastic joint grouting and leveling compounds, bitumen plastic sheeting, plastic sheeting etc. decisive, previously unknown advantages.
Die in den folgenden Beispielen belegten Vorteile beziehen sich insbesondere auf 1. Senkung des Brechpunktes 2. Oxidationsverminderung des Bitumens 3. Erhöhung der Elastizität 4. Erhöhung der Dehnfähigkeit 5. Erhöhung der Duktilität 6. erhöhung des Adhäsionsvermögens 7. Verringerung der Härte 8. bessere Lösungsfähigkeit für die zur Anwendung kommenden Kunststoffe im Bitumen 9. Verkürzung der Rührzeiten Beispiel 1 : Brechpunk@serniedrigung Brechpunkt Brechpunkt nach einer Rührzeit von 24 Std., B 100/4C bei 160 OC.The advantages demonstrated in the following examples relate in particular to 1. lowering of the breaking point 2. reduction of oxidation of bitumen 3. increase of elasticity 4. Increase in elasticity 5. Increase in ductility 6. Increase of adhesiveness 7. Reduction of hardness 8. Better solvency for the plastics used in the bitumen 9. Shortening the stirring times Example 1: Breaking point reduction Breaking point Breaking point after a stirring time of 24 hours, B 100 / 4C at 160 OC.
ohne C1 ca. -13 °C ca. -3 °C B 100/4C 85 % X Öl 15 % ca. -19 C ca. -12 C Der relativ ungesättigte Charakter des Öles bewirkt eine Herabsetzung der Oxidation des Bitumens,was sich an der unterschiedlich starken Brechpunktsänderung der Proben zeigt. without C1 approx. -13 ° C approx. -3 ° C B 100 / 4C 85% X oil 15% approx. -19 C approx. -12 C The relatively unsaturated character of the oil reduces the Oxidation of the bitumen, which is reflected in the varying degrees of change in the breaking point the samples shows.

Bei der Zinarbeitung von Kunststoffen in das Bitumen können erfindungsgemäß noch weitere Vorteile erzielt werden.Das Öl verbessert das Lösen des Kunststoffs im Bitumen und verkürzt damit die Rührzeiten beträchtlich.When processing plastics into the bitumen, according to the invention Even more advantages can be achieved. The oil improves the loosening of the plastic in the bitumen and thus considerably shortens the mixing times.
Beispiel 3 : Rührzeiten ohne Öl mit Öl ( 15 % ) 15% Solpren 480 @@ 3 Std @@ 2 Std 85% B 25 ca. 3 @@@ ca. 2 jtd Weiterhin ist es nach dem Verfahren der Erfindung möglich,die Kunststoffe zuerst im Öl zu quellen oderzulösen und diese Lösungen erst dann in das Bitumen einzuruhren.Dadurch wird eine weitere erhebliche Verkürzung der Rührzeiten erreicht.Example 3: Mixing times without oil with oil (15%) 15% Solpren 480 @@ 3 hours @@ 2 hours 85% B 25 approx. 3 @@@ approx. 2 jtd Furthermore, it is according to the procedure the invention possible to swell or dissolve the plastics first in the oil and this Only then can the solutions be poured into the bitumen. This becomes a further significant factor Shortening of the stirring times achieved.
Beispiel 4: Rührzeiten Kunststoff nur mit Kunststoff vorher Öl gemischt im 01 gelöst od.gequollen Solpren 480 15% B 25 70% ca. 2jtd. ca. 5 min.Example 4: Mixing times for plastic only mixed with plastic beforehand with oil dissolved in oil or swollen Solpren 480 15% B 25 70% approx. approx. 5 min.
Öl 1536 Das Lösen des Kunststoffes kann bei ca. 16C 0C geschehen,dauert ca. 15 min. und die so erhaltene Lösung kann bei sofortiger Verwendung ohne wesentlichen Wärmeverlust in das Bitumen eingerührt werden. Dabei vermindert die Verkürzung der rührzeit nicht nur die Kosten,sondern auch die Oxidation der bituminösen Massen.Oil 1536 The plastic can loosen at approx. 16C 0C, takes about 15 minutes and the solution obtained in this way can be used immediately Can be stirred into the bitumen without significant heat loss. Included Shortening the mixing time not only reduces costs but also reduces oxidation of the bituminous masses.
Win weiterer wesentlicher Vorteil besteht darin,daß diese uunststofflösungen nicht nur in Trimärbitumen,sondern auch in geblasenen Bitumen eingerührt werden könne.Außerdem lassen sich auch Kunststoffe wie z.B. Jynthesekautschuk,die auf Grund ihrer schlechten Löslichkeit in beispielsweise geblasenem Bitumen nur selten eingesetzt werden,verwenden. Another important advantage is that these uoplastic solutions be stirred not only into trimer bitumen, but also into blown bitumen In addition, plastics such as synthetic rubber, which are due to seldom used because of their poor solubility in, for example, blown bitumen will use.
