Description

Bleifreies Motorenbenzin der Klasse Premium/Eurosuper Unleaded premium / Eurosuper petrol
Der Gegenstand der Erfindung ist bleifreies 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 is unleaded premium / Eurosuper class petrol, which is used as engine fuel for petrol engines with a test octane number not lower than 95 units and with an engine octane number not lower than 85 units, which qualifies the product for the gasoline class Premium / Eurosuper.
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 elimienieren sollen. Als Antirezessionssicherheit werden mit Erfolg Alkalimetallverbindungen eingesetzt. Andauernd werden Versuche durchgeführt, die den Benzindampfdruck, besonders in der Sommerzeit, verrigem sollen.Rapid technical progress and the associated growth in quality of internal combustion engines place ever higher quality demands on fuel manufacturers. The environmental protection requirements force the use of different fuel components than before. Limits to eliminate lead, benzene and sulfur have become a fact. Alkali metal compounds are successfully used as anti-recession security. Experiments are constantly being carried out to reduce the gasoline vapor pressure, especially in summer.
Es wurden viele Patentanmeldungen bezüglich der verschiedenen wirtschaftlichen Losungen bei der Benzinproduktion bekannt, wie z.B.. polnische Patentanmeldung Nr P-31 1046 und auch das polnische Patent Nr. 170290, welche den Erhalt der Standardkennwerte für bleifreie Benzinarten erlauben. 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.Many patent applications have been published regarding various economic solutions in gasoline production, such as. Polish patent application No. P-31 1046 and also Polish patent No. 170290, which allow the maintenance of the standard parameters for unleaded petrol types. The corresponding combination of the hydrocarbon components with different octane numbers and the high-octane oxygen compounds has a decisive influence on the maintenance of the maximum permitted oxygen content in the fuel. The use of the highest quality raw materials enables a decisive reduction in the benzene and sulfur content, far below the standards applicable in the countries of the European Union.
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 dami 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 KraftstoffverdampfungBasically, the content of base gasoline from the cracking and reforming process can be reduced to 60% in the volume ratio of the entire fuel mixture. This reduces the aromatic hydrocarbon content. Of course, this is associated with a reduction in the octane number. Other compounds that dissolve in petrol and that have a correspondingly high octane parameter should be used here - not necessarily from the group of hydrocarbons. In this way, a motor fuel with a significantly lower aroma content can be obtained while maintaining the "octane bonus". The use of methanol and ethanol simultaneously introduces oxygen into the fuel mixture, which significantly improves the combustion process of the fuel mixture and reduces pollution However, due to low intrinsic pressure, the alcohols cause a decisive increase in this parameter in the fuel mixtures, which in turn is unfavorable for environmental protection and for excessive fuel evaporation
Es wird in diesem Fall der Einsatz von kurzkettigen Äther, wie Methyläther, Athylather, Buthylathylather 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. Ein besonders empfehlenswerter 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 bedutsam ist, die Enthalpie von MTHF ist größer als die der Kraftstoffalkohole und hat einen positiven Einfluss auf die Stabilisierung von Benzindruckparameter. Die Zύndtemperatur, der Destillationsbereich und das spezifische Gewicht, qualifizieren dieses Produkt als hochrangiges Kraftstoffadditiv.In this case, the use of short-chain ethers, such as methyl ether, ethyl ether, butyl ethyl ether, is recommended.The short-chain ethers mix with petrol just as well as heterocycle ring compounds, introduce additional oxygen atoms such as alcohols into the petrol, facilitate alcohol dissolution in the hydrocarbons, and what of is of particular importance - they reduce the fuel vapor pressure. A particularly recommended additive is methyltetrahydrofuran (MTHF), which is characterized by a very low water absorption indicator.It facilitates the dissolution of alcohols and mixes excellently with hydrocarbons, and what is important is that the enthalpy of MTHF is greater than that of fuel alcohols and has a positive one Influence on the stabilization of fuel pressure parameters. The ignition temperature, the distillation range and the specific weight qualify this product as a high-quality fuel additive.
MTHF wird aus Pflanzenabfällen in der Form einer Biomasse gewonnen. Die Reste von' Zellulose, Stroh, Spelzen, grobkörniger oder minderwertiger Makulatur, Abfallen aus der Papierfabrik und Holzabfalle sind alllgemein 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. 4897497 eingesetztMTHF is obtained from plant waste in the form of a biomass. The remains of cellulose, straw, husks, coarse-grained or low-quality waste, waste from the paper mill and wood waste are generally accessible. The production of MTHF is inexpensive and rewarding. It is used extensively in the United States under U.S. Patent No. 4897497
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 niedrigenThe 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. At extremely low
Benzindampfdruckparametern können vor allem in der Winterzeit Probleme mit dem Anlassen des Motors vorkommen. Als Abhilfemaßnahme ist der Einsatz während der Produktion von leichten, einfachen oder verzweigten Kohlenwasserstofffraktionen mit geringem Gehalt von n- und Iso-Paraffin 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 Äther. Alkoholen und MTHF bilden sie eine gute Mischung für Basisbenzin Gennate Fraktionen der Kohlenwasserstoffe beeinflussen auch vorteilhaft den Endpreis des Endproduktes Ihr Marktpreis ist niedirger als der Preis der Basisaromata oder der hochoktanigen AromataGasoline vapor pressure parameters can cause problems when starting the engine, especially in winter. As a remedial measure, use during the production of light, simple or branched hydrocarbon fractions with a low content of n- and iso-paraffin. The fractions C 4 , C 5 up 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 "octane bonus". In combination with ether. Alcohols and MTHF form a good mixture for base gasoline. Gennate fractions of the 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 Prametern und auch Benzin in den Cracken-, Reforming- und Hydrocrackenprozessen 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 KomponentenThe refineries, which carry out an extended or complete petroleum processing, have adequate facilities that enable the reception of broad and very narrow fractions of hydrocarbons with parameters favorable for gasoline production and also gasoline in the cracking, reforming and hydrocracking processes. However, the petrol types contain a wide range of aromatic hydrocarbons, often in the 40% limit. The aim is to limit the amount of base gasoline in the production of lead-free fuels in favor of the other aroma-free and benzene-free extenders, while at the same time reducing 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 zusammen gestellt 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 Verbrennungsrückstande hinterlassen 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 Behalter von unten dosieren, was die Spπtzerbildung und ein übermassiges Abdampfen verhindert In der ersten Reihenfolge soll man die schwersten Produkte, Äther und Detergens dosieren Die Alkohole - am besten mit Stabilisator und Kolosungsmittel - 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 Behälterteϊlen 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 fordert. 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. Entgegengesetztenfalls ist das Einsetzen eines umgekehrten Systems günstig. Dies fordert jedoch eines Anlageverschlusses oder der Nutzung einer Absorptionskolone mit Dampfkühlung. Die andere günstige und schnelle Methode der Mischung ist das pneumatische Rühren, d.h Eingabe der Gasphase über dem Behälterboden. Aus Sicherheitsgründen ist das Mischen mit der Hilfe von Luft unzulässig. Die zusätzlich eingeführte Luft wirkt sich negativ auf die Kraftstoffqualitat aus, so dass die Oxidationsbestandigkeϊt verringert wird. In diesem Fall sollte das Intergas, wie z.B.: Stickstoff mit gleichzeitiger Abkühlung und Rückflussabkuhlung der Dämpfe eingesetzt werden. Bei der Anwendung dieser Methode beschränkt sich der Vergleich der spezifischen Gewichte der aus den verschiedenen Behalternstande entnommenen Kraftstoffproben in einem Grenzwert von 0,002 g/cm3 Ziel der Erfindung ist eine Überarbeitung des Produktes in der Form von Benzin der Klasse Premium/Eurosuper bis hin zur Annäherung zu der Klasse Super Plus in den Optionen Bleifrei und Universal, d h mit einem Zusatz von Kalϊumverbindungen, bei uns als U 95 bekannt, bei der Beibehaltung der standig wachsenden Anforderungen der Motorproduzenten als auch von hohen proökonomischen Parametern, wobei die Grundregel auf dem Ausnutzen von bis jetzt in der Produktion eingesetzten Benzinkomponentene, jedoch bei der bedeutenden Mengenanderung und Art der Sauerstoffverbindungen beruht. Das bleifreie Motorenbenzin der Klasse Premium/Eurosuper, nach der Erfindung, welches das Basisbenzin Normal, Leichtbenzinkomponent, Detergens DAC 4303, Kraftstoffäthanol, Stabilisator/Isopropanol, C5 -Fraktion und carbochemϊsche und/oder Petrolchemische Ursprungsprodukte und/oder Produkte der Abfallverwertung enthält, ist dadurch gekennzeichnet, dass es im Volumenverhältnis Basisbenzin von 60%> - 75%, Sauerstoffverbindungen im Volumenverhältnis von 17% - 25%, Stabilisator und Kolosungsmittel im Volumenverhältnis von 1 ,25% - 5% und zu 3% im Volumenverhältnis, von Diäthylbenzol, Toluen von 0% - 35% im Volumenverhältnis, Olefinefraktion im Volumenverhältnis von 0% - 25% und vorteilhaft Kaliumverbindungen in der Menge von 10mg/1 in der Umrechnung in reines Kalium enthält, wobei als Kolosungsmittel Isopropanol und ETBE zusammen und/oder Isopropanol und Methyltetrahydrofuran zusammen eingesetzt wird. Der Gehalt an Basisbenzin ist vom Vorteil nicht hoher als 60% im Volumenverhaltnis, Die Auswahl von Mischverhältnis der Benzinkomponenten sichert nach der Erfindung entsprechende Versuchs- und Motorenoktanzahl und erlaubt eine Verringerung des Benzindampfdruckes vor allem in der Sommerzeit, beim Einhalten von entsprechenden Druckparametern in der Wϊnterzeit und gleichzeitigen Aromatagehalt unter 45% im Volumenverhältnis Die Benzingemische von bleifreien Motorenbenzin der KlasseIn order to obtain the motor gasoline with parameters that correspond to the gasoline class Premium / Eurosuper, the mixture composition should be selected so that the content of components with so-called "octane bonus" is decisive in obtaining the positive knock resistance parameters. The type and length of the carbon chains in The hydrocarbons and the aroma number - carbon compounds - should be put together in such a way that they guarantee the best combustion conditions while simultaneously using the oxygen contained in the fuel, taking into account the combustion residues generated in the engine and the emission values released into the atmosphere Production process the use of detergents, which positively influence the fuel homogeneity in minimal quantities while improving the cleaning properties at the same time and leave smaller quantities of combustion residues. The mixing process is based ht on the input into a container of the individual components in the order depending on the specific weight Raw materials should be dosed into the container from below, which prevents the formation of sparging and excessive evaporation. In the first order, the heaviest products, ether and detergent should be dosed , 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 container parts 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 urges it into 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. In the opposite case, the use of an inverted system is favorable. However, this requires a system closure or the use of an absorption colon 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 oxidation resistance is reduced. In this case, the intergas, such as: nitrogen with simultaneous cooling and reflux cooling of the vapors, should be used. When using this method, the comparison of the specific weights of the fuel samples taken from the different container levels is limited to a limit of 0.002 g / cm 3 The aim of the invention is a revision of the product in the form of gasoline of the Premium / Eurosuper class up to the approximation to the Super Plus class in the options lead-free and universal, ie with the addition of potassium compounds, known to us as U 95, at Maintaining the constantly growing requirements of engine manufacturers as well as high pro-economic parameters, whereby the basic rule is based on the exploitation of gasoline components used up to now in production, but with the significant change in quantity and type of oxygen compounds. The lead-free motor gasoline of the Premium / Eurosuper class, according to the invention, which contains the base gasoline normal, light gasoline component, detergent DAC 4303, fuel ethanol, stabilizer / isopropanol, C 5 fraction and carbochemical and / or petroleum chemical origin products and / or products of waste recycling characterized in that it contains 60%> - 75% by volume of basic gasoline, 17% - 25% by volume oxygen compounds, 1: 25% - 5% by volume stabilizer and colonicant and 3% by volume of diethylbenzene, toluene from 0% to 35% in volume ratio, olefin fraction in volume ratio from 0% to 25% and advantageously contains potassium compounds in the amount of 10 mg / 1 when converted to pure potassium, with isopropanol and ETBE together and / or isopropanol and methyltetrahydrofuran together as colonicizing agents is used. The base gasoline content is advantageously not higher than 60% in volume ratio. The selection of the mixing ratio of the gasoline components ensures according to the invention the corresponding number of test and engine octets and allows a reduction in the gasoline vapor pressure, especially in the summer time, while maintaining the appropriate pressure parameters in the winter time and simultaneous flavor content below 45% in volume ratio The gasoline blends of unleaded class petrol
