Definitions

  • the invention relates to a method having the features of the preamble of claim 1. Thereafter, the invention first relates to a process for stabilizing fuel oil and diesel oil, which, in particular after depolimerizing hydrocarbonaceous residues, was obtained by fractional distillation .. In addition, the method is used for stabilizing of pyrolysis oils, so that they can be used after the stabilization process as a fuel in heavy oil-powered units (machines).
  • machines heavy oil-powered units
  • a pyrolysis oil is produced. Pyrolysis is the heating of organic substances with the exclusion of oxygen. Delimits the pyrolysis against a thermolysis undertakes M.Krapf in Z. Angew. Chemistry 98, 1986, 413-429 , The pyrolysis process takes place in the case of so-called high-temperature pyrolysis at temperatures between 600 ° C and 800 ° C.
  • the product oil (pyrolysis oil) produced in this way has the same problem as products obtained by depalimerization, because even the pyrolysis oil is darkened by the presence of unsaturated hydrocarbons.
  • US-A-3597173 discloses a method of stabilizing petroleum distillates boiling between 24 ° C and 399 ° C, greatly reducing rubber formation during storage. The process involves the formation of soluble and insoluble gum and sludge by oxidation and / or peroxidation; then separation of insoluble gum and sludge by sedimentation, centrifugation or filtration; and then depressurized distillation or vacuum distillation to remove the soluble gum and sludge.
  • GB839552A discloses a method of stabilizing petroleum distillates boiling between 38 ° C and 649 ° C, preventing gum formation during storage. The process involves irradiating the petroleum distillate in the presence of an oxygen-containing gas to form soluble and insoluble gum and sludge; and then a separation of soluble and insoluble gum and sludge in a distillation step.
  • the object of the invention is to remove the dark coloration of diesel and heating oil, in particular if it has been obtained by depolimerization of hydrocarbon-containing residues, or of pyrolysis oil in a simple way. In particular, complex hydrogenation processes should be avoided.
  • it is proposed to first allow darkening of the diesel, heating or pyrolysis oil (hereinafter also referred to as the starting oil), in particular under oxygen access, and subsequently to transport the darkly colored starting oil to a distillation or redistillation (hereafter also referred to as Entfärbungsdestillstion) to undergo. It has been found that this process produces a bright and clear product without turbidity and keeps this product clear and bright in the long term.
  • Property values of a diesel fuel according to DIN EN 590 and property values for heating oil in accordance with DIN 51603 / could be achieved in this way, at least insofar as the sulfur contained was reduced to corresponding limits.
  • the coloring process of the starting oil can largely be prevented or slowed down considerably if the starting oil is stored, for example, under protective gas and / or in the dark in a tank, preferably with the exclusion of air and not too high temperatures.
  • the aging or inking process then proceeds very slowly, or is stopped. If, for example, you allow air to enter a source oil tank, it may take a few weeks, for example 2 or 3 weeks, until a clear color change occurs. So it may be useful, the fresh produced starting oil appropriate to lagging in order to delay the aging process.
  • an oxidative treatment e.g. performed with air.
  • the starting oil is e.g. if the air flows through it, the dark color can be set in a few seconds.
  • the Enrfärbungsdestillation can be carried out in a so-called thin-film evaporator.
  • the discolored starting oil is passed in a vacuum-maintained thin-film evaporator as a thin layer over about 180 to 240 degrees C, preferably at 200 to 230 degrees C hot evaporator surface and then condenses the resulting vapor component in particular as diesel or fuel oil ,
  • the thin-film evaporation takes place under a pressure of absolutely about 1 to 500 mbar, preferably from 2 to 100 mbar.

Claims (7)

  1. Procédé de stabilisation de fioul domestique et de gazole, obtenus par distillation fractionnée, ou d'huile de pyrolyse, issue de la pyrolyse de caoutchouc ou de matières organiques, lequel consiste à autoriser voire favoriser d'abord un assombrissement dudit gazole ou fioul domestique ou de ladite huile de pyrolyse en soumettant le gazole, le fioul domestique ou l'huile de pyrolyse à un traitement d'oxydation, pour ensuite soumettre le gazole, le fioul domestique ou l'huile de pyrolyse, lequel est désormais de couleur sombre, à une étape de distillation faisant en sorte que sa coloration sombre disparaisse, ladite distillation étant à cet effet mise en oeuvre dans un évaporateur à couche mince, en introduisant le gazole, le fioul domestique ou l'huile de pyrolyse, lequel présente une coloration altérée, dans un évaporateur à couche mince mis sous pression négative où il/elle passe, sous forme d'une couche mince, à travers une surface d'évaporation dont la température est comprise entre 180 et 240 °C, pour ainsi obtenir un constituant en phase vapeur lequel est ensuite récupéré, par condensation, sous forme de gazole ou de fioul domestique.
