Description

Verfahren zur Herstellung eines Heizöles Bei der Überführung von schweren Kohlenwasserstoffen oder Rückständen des Erdöles in niedrigsiedende Kohlenwasserstoffe durch die Druckdestillation (Krack-Verfahren) verbleibt, sofern man die Destillation nicht bis zu einem koksartigen Rückstande treibt, ein flüssiges Produkt, das als Heizöl dient. Es hat sich aber gezeigt, daß dieses Produkt beim Stehen asphalt-und harzartige Produkte abscheidet, wodurch dessen Verwendung als Heizöl beeinträchtigt wird.Process for the production of a heating oil in the transfer of heavy Hydrocarbons or residues of petroleum in low-boiling hydrocarbons by the pressure distillation (cracking process) remains, provided that the distillation does not float up to a coke-like residue, a liquid product that acts as a Heating oil is used. It has been shown, however, that this product works asphalt and when standing separates resin-like products, which affects its use as heating oil will.

Es ist nun bekannt, die Abscheidung solcher asphaltartiger Stoffe (oft auch schon vor oder während der Druckdestillation) durch Zusatz von geeigneten Lösungsmitteln zu verhindern. Als Lösungsmittel dienen dabei meist rein aromatische Kohlenwasserstoffe, die ein gutes Lösungsvermögen für die obengenannten Ausscheidungen besitzen.It is now known that such asphalt-like substances are deposited (often even before or during the pressure distillation) by adding suitable To prevent solvents. Purely aromatic solvents are usually used as solvents Hydrocarbons, which have good dissolving power for the aforementioned precipitates own.

Es wurde nun gefunden, daß die bei der Behandlung von Mineralölen mit flüssigem Schwefeldioxyd (Edeleanu-Verfahren) anfallenden Extrakte sich ganz besonders für diesen Zweck, d. h. als Lösungsmittel, eignen. Das Gemisch aus dem Rückstandsöl und dem Extrakt kann selbst nach längerem Stehen als Heizöl Verwendung finden, ohne daß zu befürchten wäre, daß die Zuleitungsröhren für den flüssigen Brennstoff sich allmählich durch Absetzen harz-und asphaltartiger Stoffe verstopfen. Dies war nicht vorauszusehen, denn bei den Extrakten aus höheren Erdölfraktionen (um die es sich meist hier handelt) ist die chemische Zusammensetzung noch ganz ungeklärt. Man spricht zwar davon, daß in ihnen der Gehalt an Stoffen der aromatischen Reihe angereichert sei; ganz ohne Zweifel handelt es sich dabei aber nicht um einfache Homologe des Benzols, sondern um Benzolderivate mit sehr langen Seitenketten. Daneben aber sind auch reichliche Mengen von ungesättigten Kohlenwasserstoffen der Fettreihe, ferner stickstoff- und schwefelhaltige Produkte sowie N aphthensäuren vorhanden. Endlich enthält jeder Extrakt auch noch geringe Mengen gesättigterer Anteile.It has now been found that in the treatment of mineral oils with liquid sulfur dioxide (Edeleanu process) obtained extracts are completely especially for this purpose, d. H. as a solvent. The mixture of the Residual oil and the extract can be used as heating oil even after standing for a long time find, without having to worry, that the supply tubes for the liquid Fuel gradually becomes clogged with the sedimentation of resinous and asphalt-like substances. This was not to be foreseen, because with the extracts from higher petroleum fractions (which is usually the case here) the chemical composition is still intact unexplained. One speaks of the fact that in them the content of substances is aromatic Row is enriched; but there is no doubt that these are not simple ones Homologues of benzene, but rather benzene derivatives with very long side chains. Besides but there are also copious amounts of unsaturated hydrocarbons of the fat series, There are also nitrogen- and sulfur-containing products as well as naphthenic acids. Finally, every extract also contains small amounts of more saturated components.

Infolgedessen war das gute Lösungsvermögen solcher Extrakte nicht vorauszusehen. Scheinbar wirken bei diesen auch noch kolloidchemische Einflüsse begünstigend auf das Inschwebehalten der asphaltartigen Körper mit.As a result, the good dissolving power of such extracts was not to foresee. Apparently colloid chemical influences also have an effect on these favoring the suspension of the asphalt-like body with.

Durch das Verfahren wird gleichzeitig ein wirtschaftlicher Fortschritt erzielt, da so zwei gewissermaßen als Abfall zu' bezeichnende Produkte einer gewerblichen Benutzung in großem Umfang zugeführt werden: das asphaltabscheidende Heizöl aus dem Rückstand von Krackanlagen und der Schwefeldioxydextrakt aus Mineralölen.At the same time, the process is an economic advance Achieved, since so two to a certain extent as waste to be 'designated products of a commercial one Use on a large scale: the asphalt-separating heating oil from the residue from cracking plants and the sulfur dioxide extract from mineral oils.

Die Menge des zuzusetzenden Extraktes richtet sich nach der Art des zu verarbeitenden Rückstandsöles. Enthält dieses viel asphalt-und harzartige Produkte, so wird man von dem Extrakt mehr zusetzen, als wenn das zu behandelnde 01 nur wenig Schwebestoffe enthält. Im allgemeinen kann gesagt werden, daB ein Zusatz von 5o °1o Extrakt zu dem Rückstandsöl immer ausreichen dürfte.The amount of extract to be added depends on the type of residual oil to be processed. Contains this much asphalt and resinous products, we will enforce from the extract more than if the treated 01 contains little suspended solids. In general it can be said that an addition of 50 ° 10 extract to the residual oil should always be sufficient.
