Description
Verfahren zur Entfernung von Natrium und/oder Vanadin aus Erdölkohlenwasserstoffen Die Erfindung bezieht sich auf ein Verfahren zur Entfernung von Natrium und/oder Vanadin aus Erdölkohlenwasserstoffen, insbesondere aus rohem Erdöl und dessen Rückständen.Process for removing sodium and / or vanadium from petroleum hydrocarbons The invention relates to a method for removing sodium and / or Vanadium from petroleum hydrocarbons, in particular from crude petroleum and its residues.
Es ist bekannt, daß Natrium und Vanadin in beträchtlichem Ausmaß aus Erdölkohlenwasserstoffen entfernt werden können, wenn man die Kohlenwasserstoffe bei erhöhter Temperatur und erhöhtem Druck in Gegenwart von Wasserstoff über Katalysatoren leitet, die aus den auf einem Metalloxyd, vorzugsweise Aluminiumoxyd, aufgebrachten Oxyden von Kobalt und Molybdän bestehen. Solche Katalysatoren sind jedoch relativ teuer, und es wurde bereits versucht, statt ihrer zur Entfernung von Natrium und Vanadin andere und billigere Materialien zu verwenden. Diese Versuche waren teilweise erfolgreich, da gefunden wurde, daß Bauxit mit Erfolg angewendet werden kann. Es wurde nun ein noch viel billigeres Material gefunden, das für den in Frage kommenden Zweck geeignet ist.It is known that sodium and vanadium are made up to a considerable extent Petroleum hydrocarbons can be removed by using the hydrocarbons at elevated temperature and pressure in the presence of hydrogen over catalysts conducts which is made up of the applied to a metal oxide, preferably aluminum oxide Oxides of cobalt and molybdenum exist. However, such catalysts are relative expensive, and attempts have already been made to remove sodium and instead of them Vanadium to use other and cheaper materials. These attempts were partial successful in that it has been found that bauxite can be used with success. It a much cheaper material has now been found that can be used for the Purpose is appropriate.
Es ist bekannt, daß Katalysatoren aus den Oxyden von Kobalt und Molybdän als solchen oder in Form von Verbindungen, die auf einem Metalloxydträger, üblicherweise Aluminiumoxyd, aufgebracht sind, bei einer Entschwefelung nach wiederholter Regeneration ständig an Aktivität verlieren. Es wurde nun gefunden, daß die Aktivität dieser Katalysatoren für die Entfernung von Natrium und Vanadin nicht mit gleicher Geschwindigkeit abnimmt und daß man die Katalysatoren zur Entfernung dieser Elemente noch verwenden kann, nachdem ihre Wirksamkeit für die Entschwefelung unter einen wirtschaftlich brauchbaren Wert abgesunken ist.It is known that catalysts are made from the oxides of cobalt and molybdenum as such or in the form of compounds on a metal oxide support, usually Aluminum oxide, are applied, in a desulfurization after repeated regeneration constantly lose activity. It has now been found that the activity of this Catalysts for the removal of sodium and vanadium do not work at the same rate decreases and that the catalysts are still used to remove these elements can after its effectiveness for desulfurization under an economical useful value has decreased.
Gemäß der Erfindung werden bei einem Verfahren zur Entfernung von Natrium und/oder Vanadin aus Erdölkohlenwasserstoffen die Kohlenwasserstoffe bei erhöhten Temperaturen und Drücken in Gegenwart von Wasserstoff über Entschwefelungskatalysatoren der vorstehend beschriebenen Art geleitet, die nach wiederholten Regenerationen ihre Entschwefelungsaktivität verloren haben.According to the invention, in a method for removing Sodium and / or vanadium from petroleum hydrocarbons contribute to the hydrocarbons elevated temperatures and pressures in the presence of hydrogen over desulfurization catalysts of the type described above, after repeated regenerations have lost their desulfurization activity.
Als Katalysatoren, die ihre Entschwefelungsaktivität verloren haben,
gelten im Sinne der Erfindung solche, die bei der Hydrofiningbehandlung eines Kuwait-Rohöls
oder Rohölrückstandes unter folgenden Bedingungen
Das erfindungsgemäße Verfahren ist auch zur Entfernung von Vanadin und/oder Natrium aus Rohölen und Rohölrückständen vor der Behandlung der Kohlenwasserstoffe über Hydrofiningkatalysatoren zur Entfernung von Schwefel geeignet. Die Hydrofiningkatalysatoren bestehen vorzugsweise aus frischen Katalysatoren der vorstehend beschriebenen Art.The method of the invention is also useful for removing vanadium and / or sodium from crude oils and crude oil residues prior to treatment of the hydrocarbons Suitable for removing sulfur via hydrofining catalysts. The hydrofining catalysts preferably consist of fresh catalysts of the type described above.
Das Verfahren gemäß der Erfindung kann innerhalb eines weiten Bereiches
von Verfahrensbedingungen durchgeführt werden.
