Description

Verfahren zur Rektifikation und Raffination von Benzin Bisher wurden die verschiedenen handelsüblichen Benzinsorten hergestellt, indem man Rohbenzin, Benzinredestillat usw., gegebenenfalls nach vorangehender Raffmation, mit Schwefelsäure in sogenannten Kolonnenapparaten durch fraktionierte Destillation in engere Fraktionen zerlegte. Diese Methode verbraucht viel Wärme und Zeit und läßt sich schwer kontinuierlich gestalten. Es ist nun gefunden worden, daß es unter Anwendung des Adsorptionsverfahrens gelingt, bei einmaliger oder allmählicher Verdampfung der ganzen Flüssigkeit und Durchleiten der Dämpfe durch adsorbierende Substanzen das Gemenge in beliebig viele und scharfe Fraktionen zu zerlegen.Processes for rectifying and refining gasoline have been used so far the various commercial gasoline types produced by using raw gasoline, Petrol redistillate etc., if necessary after prior refining, with sulfuric acid in so-called column apparatus by fractional distillation into narrower fractions disassembled. This method consumes a lot of heat and time and is difficult to be continuous design. It has now been found that using the adsorption process succeeds with single or gradual evaporation of the whole liquid and Passing the vapors through adsorbing substances the mixture in any number and to break up sharp fractions.

Es ist z. B. ein Rohbenzin vom spez. Gew. 0,750 zu fraktionieren. Es wird in einen Kessel gepumpt, -der auf z. B. 2000 C erhitzt ist, also eine Temperatur, bei der fast das ganze Benzin plötzlich verdampft. Die Dämpfe werden durch so viele mit Adsorpti'onsmittel, z. B. aktive Kohle, gefüllte Adsorber geleitet, als Fraktionen gewünscht werden, in diesem Falle z. B. vier. Damit sich die Benzindämpfe nicht schon im ersten Adsorb.er durch Abkühlung kondensieren, muß er auf entsprechend hoher Temperatur gehalten werden und die nächsten Adsorber auf immer niedrigerer Temperatur. Die Adsorber i bis ,l haben z. B. die Temperaturen i 5o', 10o0, 50° und 2o0. Da Benzindämpfe sehr leicht adsorbierbar sind, steigt durch die Adsorption selbst die Temperatur der Adsorber auf die gewünschte Höhe und braucht nicht durch Zufuhr äußerer Wärme erhalten zu werden.It is Z. B. a raw gasoline from the spec. Fractional weight 0.750. It is pumped into a boiler, -der on z. B. 2000 C, a temperature at which almost all of the gasoline suddenly evaporates. The vapors are through so many with Adsorpti'onsmittel, z. B. active charcoal, filled adsorber, are desired as fractions, in this case z. B. four. So that the gasoline vapors do not condense in the first adsorber by cooling, it must be kept at a correspondingly high temperature and the next adsorber at an ever lower temperature. The adsorbers i to, l have z. B. the temperatures i 5o ', 10o0, 50 ° and 2o0. Since gasoline vapors can be adsorbed very easily, the adsorption itself rises the temperature of the adsorber to the desired level and does not need to be maintained by supplying external heat.

Die Benzindämpfe werden von den Adsorbern in der Reihenfolge adsorbiert, daß die schwersten und höchstsiedenden in dem ersten, die leichtesten und niedrigstsiedenden in dem letzten Adsorber festgehalten werden. Nach Sättigung der- Adsorber mit den betreffenden Fraktionen werden letztere in bekannter Weise, z.B. durch Wasserdampf, ausgetrieben und kondensiert. In dem besprochenen Falle erhält man z. B. vier Fraktionen vom spei. Gew. 0,76o, 01730, 0,700 und 0,68o und einen Rückstand vom spez. Ge-,v. 0,79o. Die Kondensate werden durch das AdsoTptionsverfahren in reinster Beschaffenheit mit engen Siedegrenzen erhalten und brauchen nicht mehr fraktioniert und raffiniert zu werden.The gasoline vapors are adsorbed by the adsorbers in the order that the heaviest and highest boiling points are held in the first, the lightest and lowest boiling points in the last adsorber. After the adsorber has been saturated with the relevant fractions, the latter are expelled and condensed in a known manner, for example by means of steam. In the case discussed, one obtains z. B. four fractions from the spei. Weight 0.76o, 01730, 0.700 and 0.68o and a residue of the spec. Ge, v. 0.79o. The condensates are obtained in the purest quality with narrow boiling limits through the adsorption process and no longer need to be fractionated and refined.

Wenn für jeden Adsorber ein Ersatzadsorber vorhanden ist, welcher während des Austreibens der Dämpfe aus dem einen Adsorber eingeschaltet ist, so läßt sich das Verfahren in fortlaufendem Arbeitsgang durchführen.If there is a replacement adsorber for each adsorber, which one is switched on during the expulsion of the vapors from one adsorber, so the process can be carried out continuously.

Statt das Flüssigkeitsgemisch durch Einfließenlassen in einen ungefähr auf den höchsten Siedepunkt erhitzten Kessel. plötzlich zu verdampfen, kann man es auch durch Einleiten eines Gas- oder Luftstromes allmählich zum Verdampfen bringen, wobei das Verdampfgefäß auf. .passender Temperatur gehalten wird. Zweckmäßig läßt man auch hier die schwerstsiedenden Anteile als Rückstand im Kessel.Instead of the liquid mixture by flowing into an approximately boiler heated to the highest boiling point. suddenly evaporate, you can it also gradually by introducing a stream of gas or air to the Bring evaporation with the evaporation vessel open. .maintained a suitable temperature will. Here, too, it is expedient to leave the very heavy-boiling components as a residue in the boiler.

Es ist bekannt, Gas- und Dampfgemische von verschiedener chemischer Zusammensetzung zu trennen, indem man sie durch eine Reihe von Adsorbern leitet. Es war jedoch nicht bekannt, daß man die Rektfikation eines Flüssigkeitsgemisches dadurch herbeiführen kann, daß man es plötzlich oder -allmählich in Dampfform verwandelt und das Dampfgemisch durch ein System von Adsorbern leitet.It is known to use gas and vapor mixtures of different chemical Separate the composition by passing it through a series of adsorbers. However, it was not known to rectify a mixture of liquids can be brought about by suddenly or gradually transforming it into vapor form and passing the vapor mixture through a system of adsorbers.
