Abstract
Description
Die vorliegende Erfindung betrifft mineralische Brennstofföle, enthaltend Bestandteile pflanzlichen oder tierischen Ursprungs mit verbesserten Kälteeigenschaften sowie die Verwendung eines Additivs als Kaltfließverbesserer für derartige Brennstofföle.The present invention relates to mineral fuel oils containing ingredients of vegetable or animal origin with improved cold properties and the Use of an additive as a cold flow improver for such fuel oils.
Im Zuge abnehmender Welterdölreserven und der Diskussion um die Umwelt beeinträchtigenden Konsequenzen des Verbrauchs fossiler und mineralischer Brennstoffe steigt das Interesse an alternativen, auf nachwachsenden Rohstoffen basierenden Energiequellen (Biokraftstoffe). Dazu gehören insbesondere native Öle und Fette pflanzlichen oder tierischen Ursprungs. Dies sind in der Regel Triglyceride von Fettsäuren mit 10 bis 24 C-Atomen, die einen den herkömmlichen Brennstoffen vergleichbaren Heizwert haben, aber gleichzeitig als weniger schädlich für die Umwelt angesehen werden. Biokraftstoffe, d.h. von tierischem oder pflanzlichem Material abgeleitete Kraftstoffe werden aus erneuerbaren Quellen erhalten und erzeugen bei der Verbrennung somit nur soviel CO2, wie vorher in Biomasse umgewandelt wurde. Es ist berichtet worden, dass bei der Verbrennung weniger Kohlendioxid als durch äquivalente Mengen an Erdöldestillatbrennstoff, z.B. Dieselkraftstoff, gebildet wird und dass sehr wenig Schwefeldioxid gebildet wird. Zudem sind sie biologisch abbaubar.As world biodiesel reserves decline and the environmental consequences of fossil and mineral fuel consumption increase, so does the interest in alternative energy sources based on renewable raw materials (biofuels). These include, in particular, natural oils and fats of plant or animal origin. These are typically triglycerides of fatty acids with 10 to 24 C atoms, which have a calorific value comparable to conventional fuels, but at the same time are considered less harmful to the environment. Biofuels, ie fuels derived from animal or plant material, are obtained from renewable sources and thus produce only as much CO 2 as was previously converted into biomass. It has been reported that combustion produces less carbon dioxide than equivalent amounts of petroleum distillate fuel, eg, diesel fuel, and that very little sulfur dioxide is produced. In addition, they are biodegradable.
Aus tierischem oder pflanzlichem Material erhaltene Öle sind hauptsächlich Stoffwechselprodukte, die Triglyceride von Monocarbonsäuren umfassen, z.B. von Säuren mit 10 bis 25 Kohlenstoffatomen, und der Formel entsprechen, in der R ein aliphatischer Rest mit 10 bis 25 Kohlenstoffatomen ist, der gesättigt oder ungesättigt sein kann.Oils obtained from animal or vegetable material are mainly metabolites comprising triglycerides of monocarboxylic acids, eg of acids having 10 to 25 carbon atoms, and the formula in which R is an aliphatic radical of 10 to 25 carbon atoms, which may be saturated or unsaturated.
Im allgemeinen enthalten solche Öle Glyceride von einer Reihe von Säuren, deren Anzahl und Sorte mit der Quelle des Öls variiert, und sie können zusätzlich Phosphoglyceride enthalten. Solche Öle können nach im Stand der Technik bekannten Verfahren erhalten werden.In general, such oils contain glycerides of a number of acids whose Number and variety varies with the source of the oil, and they may additionally Contain phosphoglycerides. Such oils may be known in the art Procedures are obtained.
Auf Grund der teilweise unbefriedigenden physikalischen Eigenschaften der Triglyceride ist die Technik dazu übergegangen, die natürlich vorkommenden Triglyceride in Fettsäureester niederer Alkohole wie Methanol oder Ethanol zu überführen.Due to the partially unsatisfactory physical properties of the triglycerides The technique has begun to change the naturally occurring triglycerides in To convert fatty acid esters of lower alcohols such as methanol or ethanol.
Als Hindernis bei der Verwendung von Fettsäureestern niederer einwertiger Alkohole als Dieselkraftstoffersatz alleine haben sich deren Verhalten gegenüber Motorteilen wie insbesondere verschiedenen Dichtungsmaterialien erwiesen, die immer wieder zu Ausfällen der mit diesen aus nachwachsenden Rohstoffen hergestellten Kraftstoffe betriebenen Motoren führen. Zur Umgehung dieser Probleme wird ein Einsatz dieser auf nachwachsenden Rohstoffen basierenden Öle als Beimischung zu konventionellen Mitteldestillaten bevorzugt.As an obstacle in the use of fatty acid esters of lower monohydric alcohols As a diesel fuel substitute alone have their behavior towards engine parts such In particular, various sealing materials proved that again and again Failure of the fuels produced from these renewable raw materials run powered engines. To circumvent these problems is a use of this based on renewable raw materials as an admixture to conventional Middle distillates preferred.
Des weiteren hat sich bei der Verwendung von Triglyceriden wie auch von Fettsäureestern niederer einwertiger Alkohole als Dieselkraftstoffersatz alleine oder im Gemisch mit Dieselkraftstoff das Fließverhalten bei niedrigen Temperaturen als Hindernis erwiesen. Ursache dafür sind insbesondere ihr Gehalt an Estern gesättigter Fettsäuren sowie die hohe Einheitlichkeit (weniger als 10 Hauptkomponenten) dieser Öle im Vergleich zu Mineralölmitteldestillaten. So weist z.B. Rapsölsäuremethylester (RME) einen Cold Filter Plugging Point (CFPP) von -14°C, Sojaölsäuremethylester einen CFPP von -5°C und Tierfett einen CFPP von +9°C auf. Mit den Additiven des Standes der Technik ist es bisher oftmals nicht möglich, auf Basis dieser Ester bzw. diese Ester enthaltendem Mineraldiesel einen für die Verwendung als Winterdiesel in Mitteleuropa geforderten CFPP-Wert von -20°C sowie für spezielle Anwendungen von -22°C und darunter sicher einzustellen. Verschärft wird dieses Problem beim Einsatz von Ölen, die größere Mengen der ebenfalls gut zugänglichen Öle von Sonnenblumen und Soja enthalten. Furthermore, when using triglycerides as well as from Fatty acid esters of lower monohydric alcohols as diesel fuel substitutes alone or in the Mixed with diesel fuel, the flow behavior at low temperatures than Obstacle proved. The reason for this is especially their content of esters saturated Fatty acids as well as the high uniformity (less than 10 major components) of these Oils compared to mineral oil middle distillates. Thus, e.g. Rapsölsäuremethylester (RME) a cold filter plugging point (CFPP) of -14 ° C, soybean oil methyl ester a CFPP of -5 ° C and animal fat a CFPP of + 9 ° C. With the additives of Prior art, it is often not possible, based on this ester or these esters containing mineral diesel one for use as winter diesel in Central Europe demanded CFPP value of -20 ° C as well as for special applications of -22 ° C and below safely set. This problem is exacerbated during use of oils, the larger quantities of the likewise easily accessible oils of sunflowers and soy included.

Mit den bekannten Additiven ist es ist es bisher oftmals nicht möglich, Fettsäureester enthaltende Mitteldestillate auf einen für die Verwendung als Winterdiesel in Mitteleuropa geforderten CFPP-Wert von -20°C sowie für spezielle Anwendungen von -22°C und darunter sicher einzustellen. Problematisch bei den bekannten Additiven ist darüber hinaus eine mangelnde Sedimentationsstabilität der additivierten Öle. Die unterhalb des Cloud Points ausfallenden Paraffine und Fettsäureester sedimentieren bei längerer Lagerung unterhalb des Cloud Points und führen am Boden des Lagerbehälters zur Bildung einer Phase mit schlechteren Kälteeigenschaften.With the known additives, it is often not possible, fatty acid esters containing middle distillates to one for use as winter diesel in Central Europe demanded CFPP value of -20 ° C as well as for special applications of -22 ° C and below safely set. The problem with the known additives in addition, a lack of sedimentation stability of the additized oils. The sedimenting paraffins and fatty acid esters precipitating below the cloud point for longer storage below the cloud point and lead to the bottom of the Storage container to form a phase with poorer cold properties.
Es bestand somit die Aufgabe, Brennstofföle mit verbesserten Kälteeigenschaften zur Verfügung zu stellen, die Mitteldestillate und Fettsäureester enthalten, wobei deren CFPP-Werte bei -20°C und darunter liegen. Ferner soll die Sedimentation ausgefallener Paraffine und Fettsäureester bei längerer Lagerung des Brennstofföls im Bereich seines Cloud Points bzw. darunter verlangsamt oder verhindert werden.It was therefore the task of fuel oils with improved cold properties for To provide available, the middle distillates and fatty acid esters, wherein the CFPP values are at -20 ° C and below. Furthermore, the sedimentation should be more unusual Paraffins and fatty acid esters during prolonged storage of the fuel oil in the area of its Cloud points or slowed down or prevented.
