Abstract
Description
Der Gegenstand der Erfindung betrifft ein bleibfreies Motorenbenzin der Klasse Premium/Eurosuper, das als Motorkraftstoff für Ottomotoren mit der Versuchsoktanzahl nicht niedriger als 95 Einheiten und mit der Motoroktanzahl nicht niedriger als 85 Einheiten verwendet wird, was das Produkt zu der Benzinklasse Premium/Eurosuper qualifiziert.The object of the invention relates to a lead-free Motor gasoline of the premium / Eurosuper class, which as Engine fuel for gasoline engines with the test octane number not lower than 95 units and with the engine octane number not lower than 85 units is used, what that Product qualified for the Premium / Eurosuper gasoline class.
Schneller technischer Fortschritt und damit verbundenes Qualitätswachstum der Verbrennungsmotoren stellen an die Kraftstoffhersteller immer höhere Qualitätsanforderungen. Die Umweltschutzanforderungen zwingen zum Einsatz von anderen Kraftstoffkomponenten als bisher. Zur Tatsache wurden Begrenzungen, die Blei, Benzol und Schwefel eliminieren sollen. Als Antirezessionssicherheit werden mit Erfolg Alkalimetallverbindungen eingesetzt. Andauernd werden Versuche durchgeführt, die den Benzindampfdruck, besonders in der Sommerzeit, verringern sollen.Fast technical progress and related Quality growth of the internal combustion engines is in line with Fuel manufacturers have ever higher quality requirements. The environmental protection requirements force the use of different fuel components than before. To the fact were limits that lead, benzene and sulfur should eliminate. As anti-recession security with Success used alkali metal compounds. constantly tests are carried out to determine the gasoline vapor pressure, especially in summer.
Es wurden viele Patentanmeldungen bezüglich der verschiedenen wirtschaftlichen Lösungen bei der Benzinproduktion bekannt, wie z.B. polnische Patentanmeldung Nr. P-311046 und auch das polnische Patent Nr. 170290, welche den Erhalt der Standardkennwerte für bleifreie Benzinarten erlauben.There have been many patent applications relating to the various economic solutions at the Known gasoline production, e.g. Polish Patent application No. P-311046 and also the Polish patent No. 170290, which indicates the receipt of the standard parameters for Allow unleaded types of gasoline.
Die entsprechende Zusammenstellung der Kohlenwasserstoffkomponenten mit unterschiedlicher Oktanzahl und der hochoktanigen Sauerstoffverbindungen hat einen entscheidenden Einfluss auf die Erhaltung des maximal zugelassenen Sauerstoffgehalts im Kraftstoff. Der Einsatz von Rohstoffen der höchsten Qualität ermöglicht eine entscheidende Verringerung des Benzol- und Schwefelgehalts, weitaus unter den in den Ländern der Europäischen Union geltenden Normen.The corresponding compilation of the Hydrocarbon components with different Octane number and the high octane oxygen compounds a decisive influence on the preservation of the maximum approved oxygen content in the fuel. The stake of raw materials of the highest quality enables one decisive reduction in the benzene and sulfur content, far among those in the countries of the European Union applicable standards.
Grundsätzlich kann der Gehalt von Basisbenzin aus dem Cracken- und Reformingprozess auf 60 % im Volumenverhältnis der ganzen Kraftstoffmischung verringert werden. Der Gehalt an aromatischen Kohlenwasserstoffen wird damit verringert. Selbstverständlich ist das mit der Senkung der Oktanzahl verbunden. Hier sollte auf andere Verbindungen zurückgegriffen werden, die sich in Benzin auflösen, und die einen entsprechend hohen Oktanparameter haben - nicht unbedingt aus der Gruppe der Kohlenwasserstoffe. Auf diese Weise kann ein Motorkraftstoff mit bedeutend kleinerem Aromagehalt bei gleichzeitiger Erhaltung des "Oktanbonusses" erzielt werden. Die Anwendung von Methanol und Ethanol führt gleichzeitig den Sauerstoff in das Kraftstoffgemisch ein, das den Verbrennungsprozess der Kraftstoffmischung entscheidend verbessert und die Umweltverschmutzung verringert. Trotz einem ziemlich niedrigen Eigendruck verursachen die Alkohole jedoch in den Kraftstoffmischungen eine entscheidende Steigerung dieses Parameters, was wiederum für den Umweltschutz ungünstig ist sowie für die übermäßige Kraftstoffverdampfung.Basically, the content of base gasoline can be obtained from the Cracking and reforming process to 60% in volume ratio of the whole fuel mixture can be reduced. The salary aromatic hydrocarbons are reduced. Of course, this is with the lowering of the octane number connected. Here should be on other connections be used, which dissolve in gasoline, and who have a correspondingly high octane parameter - not necessarily from the group of hydrocarbons. To this Way, an engine fuel with significantly smaller Aroma content while maintaining the "Octane bonus" can be achieved. The application of methanol and ethanol simultaneously introduces the oxygen into the A fuel mixture that the combustion process of Fuel mixture significantly improved and that Pollution reduced. Despite one pretty However, the alcohols in the Fuel blends a crucial boost to this Parameters, which in turn is unfavorable for environmental protection as well as for excessive fuel vaporization.
Es wird in diesem Fall der Einsatz von kurzkettigen Äther, wie Methyläther, Äthyläther, Buthyläthyläther empfohlen. Die kurzkettigen Äther mischen sich mit Benzin genauso gut wie Heterozyklenringverbindungen, führen zusätzliche Sauerstoffatome wie Alkohole in das Benzin ein, erleichtern die Alkoholauflösung in den Kohlenwasserstoffen, und was von besonderer Bedeutung ist, sie verringern den Kraftstoffdampfdruck. In this case, the use of short-chain ether, such as methyl ether, ethyl ether, butyl ethyl ether recommended. The short chain ether mixes with gasoline just as well like heterocycle ring connections, lead additional ones Oxygen atoms such as alcohols in the gasoline, facilitate the alcohol dissolution in the hydrocarbons, and what is of particular importance, they reduce the The fuel vapor pressure.
Ein besonders empfehlendswertes Additiv ist Methyltetrahydrofuran (MTHF). Er zeichnet sich durch einen sehr niedrigen Wasseraufnahmeindikator aus. Er erleichtert die Auflösung von Alkoholen und mischt sich hervorragend mit Kohlenwasserstoffen, und was bedeutsam ist, die Enthalpie von MTHF ist größer als die der Kraftstoffalkohole und hat einen positiven Einfluss auf die Stabilisierung von Benzindruckparameter. Die Zündtemperatur, der Destillationsbereich und das spezifische Gewicht qualifizieren dieses Produkt als hochrangiges Kraftstoffadditiv.A particularly recommendable additive is Methyl tetrahydrofuran (MTHF). He is characterized by one very low water intake indicator. He relieved the dissolution of alcohols and mixes excellently with hydrocarbons, and what's important, the Enthalpy of MTHF is greater than that of Fuel alcohols and has a positive impact on that Stabilization of fuel pressure parameters. The Ignition temperature, the distillation area and that specific weight qualify this product as high-level fuel additive.
MTHF wird aus Pflanzenabfällen in der Form einer Biomasse gewonnen. Die Reste von Zellulose, Stroh, Spelzen, grobkörniger oder minderwertiger Makulatur, Abfällen aus der Papierfabrik und Holzabfälle sind allgemein zugänglich. Die Produktion von MTHF ist preisgünstig und lohnend. In den Vereinigten Staaten von Amerika wird sie im großen Ausmaß nach dem USA-Patent Nr. 4,897,497 eingesetzt.MTHF is made from plant waste in the form of a biomass won. The remains of cellulose, straw, husks, coarse-grained or inferior waste, waste from the paper mill and wood waste are generally accessible. The production of MTHF is inexpensive and rewarding. In the United States of America it will be large Extent used in U.S. Patent No. 4,897,497.
Auf die Verringerung des Dampfdruckes fließt vorteilhaft Zusatz von Diäthylbenzol (DEB) ein, welcher bei dem vergrößerten Oxidgehalt in Benzin die Verbrennungsbedingungen nicht verringert und zusätzlich durch die hohe Oktanzahl gekennzeichnet wird. Bei extrem niedrigen Benzindampfdruckparametern können vor allem in der Winterzeit Probleme mit dem Anlassen des Motors vorkommen. Als Abhilfemaßnahme wird während der Produktion der Einsatz von leichten, einfachen oder verzweigten Kohlenwasserstofffraktionen mit geringem Gehalt von n- und Iso-Paraffin vorgeschlagen. Die Fraktionen C4, C5 bis zu C8 mit der erwähnten Struktur, die durch die minimale Oktanzahl 67 gekennzeichnet werden, vergrößern günstig den Druck bei dem geringen Abfall des "Oktanbonusses". In der Verbindung mit dem Äther, Alkoholen und MTHF bilden sie eine gute Mischung für Basisbenzin. Genannte Fraktionen der Kohlenwasserstoffe beeinflussen auch vorteilhaft den Endpreis des Endproduktes. Ihr Marktpreis ist niedriger als der Preis der Basisaromata oder der hochoktanigen Aromata.The addition of diethylbenzene (DEB), which does not reduce the combustion conditions due to the increased oxide content in gasoline and which is additionally characterized by the high octane number, is advantageous in reducing the vapor pressure. With extremely low gasoline vapor pressure parameters, problems with starting the engine can occur, especially in winter. As a remedy, the use of light, simple or branched hydrocarbon fractions with a low content of n- and iso-paraffin is proposed during production. The fractions C 4 , C 5 to C 8 with the structure mentioned, which are characterized by the minimum octane number 67, favorably increase the pressure with the slight drop in the "octane bonus". In combination with ether, alcohols and MTHF, they form a good mixture for base gasoline. The aforementioned fractions of hydrocarbons also have an advantageous effect on the final price of the end product. Their market price is lower than the price of the basic or high-octane flavor.
Die Raffineriebetriebe, die eine erweiterte oder komplette Erdölverarbeitung durchführen, verfügen über angemessene Anlagen, die das Erhalten von breiten sowie von sehr schmalen Fraktionen von Kohlenwasserstoffen mit für die Benzinproduktion günstigen Parametern und auch Benzin in den Crack-, Reforming- und Hydrocrackprozessen ermöglichen. Die Benzinsorten enthalten jedoch einen breiten Bereich von aromatischen Kohlenwasserstoffen, oft in den Grenzwerten von 40 %. Ziel ist es also, die Mengen von Basisbenzin in der Produktion von bleifreien Kraftstoffen zugunsten der anderen aromafreien und benzolfreien Streckungsmitteln einzuschränken, bei gleichzeitiger Senkung der Produktionskosten durch den Einsatz von preisgünstigen und leicht zugänglichen Komponenten.The refineries that have an expanded or complete Perform petroleum processing have adequate Plants that get wide as well as very narrow fractions of hydrocarbons with for the Gasoline production favorable parameters and also gasoline in enable the cracking, reforming and hydrocracking processes. However, the petrol types contain a wide range of aromatic hydrocarbons, often in the limit values of 40%. So the goal is to get the amounts of base gasoline in the production of unleaded fuels in favor of other flavor-free and benzene-free extenders restrict while lowering the Production costs through the use of inexpensive and easily accessible components.
Um das Motorenbenzin mit Parametern zu erhalten, die der Benzinklasse Premium/Eurosuper entsprechen, sollte die Gemischzusammensetzung so gewählt werden, dass der Gehalt an Komponenten mit sog. "Oktanbonus" bei dem Erhalten der positiven Klopffestigkeitsparametern maßgebend wird. Die Art und die Länge der Kohlenstoffketten in den Kohlenwasserstoffen sowie die Aromazahl - Kohlenstoffverbindungen - sollen so zusammengestellt werden, dass sie bei der gleichzeitigen Ausnutzung des in dem Kraftstoff enthaltenen Sauerstoffes beste Verbrennungsbedingungen garantieren, mit Berücksichtigung der in dem Motor entstandenen Verbrennungsrückstände und der in die Atmosphäre abgegebenen Emissionswerte. Vorteilhaft ist in dem Produktionsprozess der Einsatz von Detergens, welche in minimalen Mengen die Kraftstoffhomogenität bei der gleichzeitigen Verbesserung der Reinigungseigenschaften positiv beeinflussen und geringere Mengen der Verbrennungsrückstände hinterlassen.To get the motor gasoline with parameters that the Petrol class Premium / Eurosuper should correspond to Mixture composition should be chosen so that the content on components with so-called "octane bonus" when receiving the positive knock resistance parameters becomes decisive. The Type and length of carbon chains in the Hydrocarbons and the number of flavors - Carbon compounds - should be put together like this that they are in the simultaneous use of the in best of all the oxygen contained in the fuel Guarantee combustion conditions, taking into account the combustion residues generated in the engine and the emission values released into the atmosphere. The use of is advantageous in the production process Detergent, which in minimal amounts Fuel homogeneity with simultaneous improvement the cleaning properties positively and leave smaller amounts of combustion residues.
Der Mischungsprozess beruht auf der Eingabe in einen Behälter der einzelnen Komponenten in der von dem spezifischen Gewicht abhängigen Reihenfolge. Die Rohstoffe soll man in den Behälter von unten dosieren, was die Spritzerbildung und ein übermäßiges Abdampfen verhindert. In der ersten Reihenfolge soll man die schwersten Produkte, Äther und Detergens dosieren. Die Alkohole - am bestem mit Stabilisator und Kolösungsmittel - sollen zum Schluss dosiert werden. In der Produktion, besonders bei dem Anwenden von Großvolumenbehältern ist das Einspritzverfahren, bei dem unter hohen Druck die weiteren Komponenten eingepumpt werden, welches aber immer noch in Deutschland verwendet wird, sehr ungünstig, weil es das Erhalten eines homogenen Produktes im ganzen Behältervolumen nicht zulässt. Der Unterschied der spezifischen Gewichte, der in den verschiedenen Behälterteilen gemessen wird, überschreitet den Wert 0,03 g/cm3. Die günstigste Methode ist die Zirkulationsmethode, bei welcher die Umlaufpumpe benutzt wird, die den Kraftstoff aus dem oberen Behälterteil entnimmt und ihn in seinen unteren Bereich fördert. In der kurzen Zeit kann man den Kraftstoff bei der gleichzeitigen maximalen Einschränkung der Dampfemission homogenisieren, wobei das allerdings nur bei der Ausnutzung des maximalen Behältervolumens möglich ist. Dies erfordert jedoch einen Anlageverschluss oder die Nutzung einer Absorptionskolonne mit Dampfkühlung. Die andere günstige und schnelle Methode der Mischung ist das pneumatische Rühren, d.h. Eingabe der Gäsphase über dem Behälterboden. Aus Sicherheitsgründen ist das Mischen mit der Hilfe von Luft unzulässig. Die zusätzlich eingeführte Luft wirkt sich negativ auf die Kraftstoffqualität aus, so dass die Oxidationsbeständigkeit verringert wird. In diesem Fall sollte das Intergas, wie z.B. Stickstoff mit gleichzeitiger Abkühlung und Rückflussabkühlung der Dämpfe eingesetzt werden. Bei der Anwendung dieser Methode beschränkt sich der Vergleich der spezifischen Gewichte der aus den verschiedenen Behälterstände entnommenen Kraftstoffproben in einem Grenzwert von 0,002 g/cm3.The mixing process is based on the input into a container of the individual components in the order depending on the specific weight. The raw materials should be dosed into the container from below, which prevents splashing and excessive evaporation. In the first order you should dose the heaviest products, ether and detergent. The alcohols - preferably with stabilizer and cosolvent - should be dosed at the end. In production, especially when using large volume containers, the injection process, in which the other components are pumped in under high pressure, but which is still used in Germany, is very unfavorable because it does not allow a homogeneous product to be obtained in the entire container volume. The difference in specific weights measured in the various parts of the container exceeds 0.03 g / cm 3 . The cheapest method is the circulation method, in which the circulation pump is used, which takes the fuel from the upper part of the tank and delivers it to its lower area. In the short time, the fuel can be homogenized with the simultaneous maximum limitation of the steam emission, although this is only possible when the maximum tank volume is used. However, this requires a system closure or the use of an absorption column with steam cooling. The other cheap and quick method of mixing is pneumatic stirring, ie entering the gas phase above the bottom of the container. For safety reasons, mixing with the help of air is not permitted. The additionally introduced air has a negative effect on the fuel quality, so that the resistance to oxidation is reduced. In this case, the intergas, such as nitrogen, should be used with simultaneous cooling and reflux cooling of the vapors. When using this method, the comparison of the specific weights of the fuel samples taken from the various tank levels is limited to a limit of 0.002 g / cm 3 .
