Abstract

A fuel composition comprising a gas oil base fuel, an alkyl levulinate and one or more additional components, each of which components contains one or more aromatic constituents; and a method of reducing the phase separation temperature of a fuel composition.

Description

Fuel composition
Technical field
The present invention relates to contain the fuel composition of gas oil basic fuel, particularly comprise this composition of levulinate and relate to their preparation and purposes.
Background technology
Known two kinds of different fuel elements are mixed to improve the performance and/or the performance of resultant composition, show as engine.
Known diesel oil fuel component comprises the what is called " biofuel " that obtains from biomaterial.Example comprises levulinate.
Levulinate (ester of levulinic acid) and be described in Zh.Prikl.Khim. (Leningrad) (1969) 42 (4) by the method that makes the reaction of suitable alcohol and furfuryl acetate prepare them, 958-9 and methyl esters, ethyl ester, propyl ester, butyl ester, pentyl ester and own ester in particular.
WO-A-94/21753 discloses the fuel that comprises gasoline and diesel oil that is used for oil engine, and this fuel comprises the C of certain proportion (as 1-90%v, 1-50%v, preferred 1-20%v) 4-6Ketone group-carbonic acid (preferred levulinic acid) and C 1-22The ester of alcohol.With C 1-8The ester of alcohol is described to be particularly suitable for being included in the gasoline and and C 9-22The ester of alcohol is described to be particularly suitable for being included in the diesel oil.
Embodiment among the WO-A-94/21753 comprises a certain amount of levulinate in gasoline, be used to improve octane value (RON and MON).
WO-A-03/002696 discloses the fuel composition of introducing levulinic acid or its functional derivatives, purpose is to compare the oxygen that more volumes are provided with ethanol or traditional oxygenatedchemicals such as MTBE or ETBE, makes the increase of fuel Reid vapor pressure less or do not increase and the less or not influence to the flash-point influence of basic fuel.Described functional derivatives is alkyl derivative preferably, more preferably C 1-10Alkyl derivative.It is said preferably ethyl levulinate, and methyl ester levulinate is preferred surrogate.Levulinic acid or functional derivatives are preferred for forming the 0.1-5%v of fuel.
Tend to make present commercially available ignition (diesel oil) engine optimization that the fuels run of required specification is arranged with apparatus.In addition, require the condition of operation engine can influence the mode that the fuel composition in the engine wherein works.Especially, when free air temperature descended, for the fuel of single-phase uniform liquid may become multi-phase fluid, this was because some component (i) is solidified (formation solid wax) or (ii) unmixing and form independent liquid level in bulk liquid under normal temps.Begin the temperature (it is called fuel " cloud point ") that is characterized as fuel transparency change and this variation of generation that wax forms during cooling.If when cooling, before cloud point, form independent liquid phase, the temperature that then forms this independent liquid phase is called " phase separation temperature ".Diesel oil specification such as ASTMD975-02 (USA) and EN590 (Europe) comprise that the boundary of cloud point temperature is to guarantee that diesel oil is fluid and to prevent that fuel filter is by the paraffin blockage plug under minimum expection working temperature.In order to make not trouble of operation, also need the diesel oil in the diesel fuel tank to keep evenly, this is because the composition of part or all of any isolating liquid level may be not suitable as the fuel of engine.Therefore the normal business diesel base fuel is mixed with other fuel element can be the performance of blend in its engine that is intended for use be had adverse influence for improving overall fuel performance and/or performance.
Owing to above reason, need be near the mark the as far as possible overall specifications of commercially available diesel base fuel of the overall specifications of various diesel fuel blending thing, engine tends to be optimized at this basic fuel.
But because any other fuel element may change the performance and the performance of basic fuel, this may be difficult to reach.The performance of blend in addition, particularly it always can simply directly not predicted from the performance of independent composition fuel the influence of low temperature performance.
Be surprisingly found out that now the phase separation temperature of fuel composition depends on the content of aromatics composition in the basic fuel in the fuel composition that contains gas oil basic fuel and levulinic acid alkyl ester.Especially, when increasing the content of aromatics composition, phase separation temperature descends.In addition, under specific temperature, if increase the content of aromatics composition, the amount of the levulinic acid alkyl ester that then can introduce in uniform mixture increases.

The compatibility of various levulinic acid alkyl esters is measured in use based on the method for ASTM D2500 " cloud point " process.In this process, the sample (40ml) of fuel is cooled off from envrionment temperature (20 ℃) a series of remaining in the thermostatic bath that reduces gradually under the temperature.When sample is cooled to its wax cloud point, it is checked at interval by 1 ℃.The wax cloud point of describing in ASTM D2500, two other temperature that record conforms to following observed situation, condition are that they occur:
(1) muddy first the appearance,
(2) the independent signal first that comes off of liquid phase.
In each case, cooling lasts till wax cloud point-more than the wax cloud point, because sample becomes opaque, is separated thereby can not observe further reliably.
With the blending and measure the compatibility of every kind of blend under various concentration of ester ethyl levulinate, the positive butyl ester of levulinic acid and the solution of levulinic acid n-pentyl ester in fuel A.The results are shown in following table 3.
