Description

Verfahren zur Raffifation leicht siedender Kohlenwasserstoffe. Die bei der Gewinnung von Benzin verschiedenartigster Provenienz zunächst anfallenden Rohprodukte werden bekanntlich in der Weise raffiniert, daß man sie, in vielen Fällen wiederholt, mit konzentrierter Schwefelsäure und alsdann mit Natronlauge wäscht. An Stelle der ersteren hat man auch anhvdridhaltige Schwefelsäure oder Chromat-Schwefelsäure empfohlen sowie eine Reihe anderer oxydierend, reduzierend, kondensierend und neutralisierend wirkender Mittel.Process for refining low-boiling hydrocarbons. the in the production of gasoline of various origins It is well known that raw products are refined in such a way that, in many cases, they can be used washed repeatedly with concentrated sulfuric acid and then with sodium hydroxide solution. In place of the former one also has anhydride-containing sulfuric acid or chromate-sulfuric acid recommended as well as a number of others oxidizing, reducing, condensing and neutralizing effective means.

Es wurde nun gefunden, daß man auf weit einfachere und wohlfeilere Weise die gewünschte Raffination durchführen kann. Löst man nämlich die niedrig, etwa bis 2oo° siedenden Anteile des Rohbenzins in hydrierten Naphthalinen, und zwar vornehmlich in Tetrahydronaphthalin und erhitzt alsdann diese Lösung, so bleiben auffallenderweise die dem Benzin anhaftenden Verunreinigungen in den hydrierten N aphthalinen gelöst, während das abdestillierende Benzin in reiner Form gewonnen wird. Der gleiche Effekt läßt sich feststellen, wenn man an Stelle von Benzin Rohbenzol wie auch andere leicht siedende Kohlenwasserstoffe in der beschriebenen Weise mit hydrierten Naphthalinen behandelt.It has now been found that one can go for far simpler and cheaper ones Way can carry out the desired refining. If you solve the low, about up to 2oo ° boiling fractions of the raw gasoline in hydrogenated naphthalenes, namely mainly in tetrahydronaphthalene and then heated this solution, so remain Strikingly, the impurities adhering to the gasoline in the hydrogenated N aphthalenes dissolved, while the distilling gasoline was obtained in pure form will. The same effect can be seen if raw benzene is used instead of gasoline as well as other low-boiling hydrocarbons in the manner described treated hydrogenated naphthalenes.

Besonders zweckmäßig wird das Verfahren in der Weise durchgeführt, daß man die zu raffinierenden Kohlenwasserstoffe in gas-bzw. dampfförmigem Zustand durch hydrierte N aphthaline hindurchleitet, die ihrerseits auf eine über dem Siedepunkt der zu reinigenden Kohlenwasserstoffe liegende Temperatur erhitzt sind. Man kann beispielsweise durch Einbau eines heizbaren-Tetrahydronaphthalin-Waschers auf einfachste und äußerst wirtschaftliche Weise das erzielen, was bisher nur durch die mehrere Arbeitsprozesse erheischende Behandlung mit verschiedenen bei der Reinigung verbrauchten Chemikalien möglich war.The method is particularly expediently carried out in such a way that that the hydrocarbons to be refined in gas or. vaporous state through hydrogenated naphthalenes, which in turn are at one above the boiling point the hydrocarbons to be cleaned are heated. One can for example, by installing a heatable tetrahydronaphthalene washer in the simplest way and in an extremely economical way to achieve what has hitherto only been achieved through several Work processes requiring treatment with various consumed in cleaning Chemicals was possible.
