  Procédé de dissociation d'huiles minérales. 



   L'invention concerne un procédé de dissociation d'huiles minérales,d'huiles de goudron et de leurs   substances-mères,telles   que   l'huile   brute,le goudron brut, etc 
Dans la dissociation d'huiles à point d'ébullition élevé, en particulier d'huiles contenant des éléments à point d'ébulli- tion très élevé ou du carbone libre,telles que le goudron de houille,le goudron de lignite,etc,on a constaté qu'il n'est pas rationnel de dissocier complètement la matière brute parce que les huiles se décomposent très facilement à la haute température nécessaire pour la dissociation jusqu'à ce qu'il se   séparedu   carbone,ce qui peut causer des engorgements ou entrainer   d'au-   tres inconvénients.. 



   C'est pourquoi on a constaté qu'il convient de ne dissocier que les huiles les plus légères à une température relativement basse et de laisser. s'écouler   continellement   la partie non dis- sodée'. 

 <Desc/Clms Page number 2> 

 



   Le procédé est mis en pratique en présence   d'hydrogéne   ou de gaz contenant de l'hydrogène à l'aide d'un corps de contact liqui de la température de la réaction. Les matières sont injectées de préférence à l'aide du gaz de protection dans le récipient contenant la substance de contact. On réalise ainsi l'avantage d'une dissociation complète des huiles les plus légères sans aucun dépôt de carbone. 



  Exemplede réalisation.- Pulvériser et injecter 100 kg. de   goudror   àl'aide de gaz-tels que de l'hydrogène ou un gaz contenant de 1 l'hydrogène à travers un ajutage dans un récipient contenant la substance de contact liquide. Maintenir la température à 300-400   environ. 



   Laisser écouler continuellement par un   dispositif/   appro- prié quelconque l'huile non dissociée dans ces conditions. 



   On a bien déjà proposé de chauffer les matières premières pendant peu de temps jusqu'à des températures d   360   à 420   C. pour transformer l'huile minérale visqueuse ou les résidusde la distillation de l'huile minérale en   hydrocsrbures   moins vis- queux mais dans ce procédé on cherche à éviter autant que possi- ble toute dissociation des huiles. 



   Au contraire le présent procédé vise précisément une disso- cia.tion des huiles. Cette dissociation a lieu complètement dans les conditions indiquées.

  Process for dissociating mineral oils.



   The invention relates to a process for dissociating mineral oils, tar oils and their parent substances, such as crude oil, crude tar, etc.
In the dissociation of high boiling point oils, in particular oils containing very high boiling point elements or free carbon, such as coal tar, lignite tar, etc. found that it is not rational to completely dissociate the raw material because oils decompose very easily at the high temperature necessary for dissociation until it separates from carbon, which can cause blockages or cause other drawbacks.



   That is why it has been found that it is appropriate to dissociate only the lightest oils at a relatively low temperature and leave. the non-dissolved portion continuously flows.

 <Desc / Clms Page number 2>

 



   The process is carried out in the presence of hydrogen or a gas containing hydrogen using a contact body liquid at the temperature of the reaction. The materials are preferably injected with the aid of the shielding gas into the container containing the contact substance. This achieves the advantage of complete dissociation of the lightest oils without any carbon deposition.



  Example of realization - Spray and inject 100 kg. gouding using gases such as hydrogen or a gas containing hydrogen through a nozzle into a vessel containing the liquid contact substance. Maintain the temperature at about 300-400.



   Allow the undissociated oil to drain continuously by some suitable device under these conditions.



   It has already been proposed to heat the raw materials for a short time up to temperatures of 360 to 420 C. in order to transform the viscous mineral oil or the residues of the distillation of mineral oil into less viscous hydrocrbons but in this process seeks to avoid any dissociation of the oils as much as possible.



   On the contrary, the present process is aimed precisely at a breakdown of oils. This dissociation takes place completely under the conditions indicated.

RESUME. ABSTRACT. Procédé de dissociation des huiles minéral es,caractérisé pa le fait quon ne provoque qu'une dissociation des éléments dont le point d'ébullition est le plus bas, en utilisant des températu- res de réaction relativement basses en présence de catalyseurs liquides à la température de la réaction et d'hydrogène ou de gaz de protection contenant de l'hydrogène et qu'on laisse écouler continuellement les parties non dissociées ayant un point d'ébullition plus élevé. Process for dissociating mineral oils, characterized by the fact that only the dissociation of the elements with the lowest boiling point is caused by using relatively low reaction temperatures in the presence of catalysts which are liquid at the temperature. of the reaction and hydrogen or shielding gas containing hydrogen, and the undissociated parts having a higher boiling point are allowed to flow continuously.
