Description
Technical field
The present invention relates to it is a kind of suitable for the pour point reducer composition of biodiesel-petrifaction diesel blending oil, preparation method and
It is applied, and belongs to biomass energy source additive research and development technology field.
Background technology
With China's rapid development of economy, a large amount of burn of fossil fuel causes seriously to the life of environment and people
Influence.Limited fossil energy and the environmental problem of getting worse so that there is an urgent need to a kind of sustainable development by people
Green energy resource.Biodiesel be by free fatty or the alcohols such as animal and plant fat and methanol, ethanol under the action of catalyst,
The mixed aliphatic ester of esterification generation occurs.Biodiesel has many advantages that first, raw material sources are extensive, and price is low
It is honest and clean, belong to regenerative resource；Secondly, biodiesel is nontoxic, and sulfur content is low, environmentally protective, is very beneficial to environment, is that one kind can
Regenerated clean fuel, is effective substitute of fossil energy, can greatly alleviate the pressure that energy scarcity is brought to society, draw
The extensive concern of domestic and international more and more scientific workers is played.
Biodiesel is made of polyunsaturated fatty acid ester and unsaturated fatty acid ester, and due to it, there are substantial amounts of saturated fat
Acid esters, have impact on the low temperature flow of biodiesel, in cold weather, since temperature is very low, it is easily formed crystal, from
And hinder free-flowing of the fuel in oil pipeline and filter and then influence the normal operation of engine, therefore improve
The low temperature flow of biodiesel is that people urgently solve the problems, such as.
Solving the problems, such as that biodiesel lower-temperature fluidity is poor takes following several measures at present：1) winterization is handled；2) change
Become biodiesel structure；3) petrifaction diesel is blended；4) cold flow improver is added.Since winterization processing yield is relatively low, resource
Waste seriously, its cost of change biodiesel structure is higher, it is difficult to realize industrialization, therefore common method only has and petrifaction diesel
Blending and addition cold flow improver.Research has shown that, the vehicle fuel of 20% biodiesel is added in petrifaction diesel, with phase
Cigarette, particle, carbon monoxide, hydrocarbon and sulfide emission can be reduced by answering pure petrifaction diesel to compare.In addition, biodiesel is also
The lubricant of petrifaction diesel can be served as, reduces the abrasion of engine, substantially increases the service life of engine.In biology
Pour-point depressant, arrangement mode and interaction of the pour point depression agent molecule by varying biodiesel molecule, so as to control are added in diesel oil
The form of crystallization, the conformation of the flat crystal generation, in addition pour point depression agent molecule holding stretching, extension that avoid particle diameter larger and easily assemble,
And have stronger adsorption capacity to biodiesel molecule, more conducively control the shape of crystal.Although pour-point depressant can improve biology
The low temperature flow of diesel oil, reduces its cold filter plugging point and condensation point, but effect is not but apparent.This is primarily due to pour-point depressant
It is high molecular polymer, sticky liquid, oneself viscosity is very big, is not easy to flow, and generally requires and adds in biodiesel is added to
Thermal agitation, so can just be such that pour-point depressant is preferably dispersed in biodiesel, so as to reach more preferable depression effeCt.O-phthalic
Esters of gallic acid and acetate esters organic solvent usually have good dissolubility, itself has certain pour point depression to imitate for biodiesel
Fruit, does not interfere with the combustibility of biodiesel, smaller additionally, due to its molecular weight, when being compounded with pour-point depressant, it is easier to
With pour-point depressant molecule contacts and modifying it, make its in biodiesel dispersedly more uniformly, so as to improve it in life
Disperse in thing diesel oil uneven and the problem of be not easy to flow.Add at low temperature has containing phthalate and acetate esters
After the pour point reducer composition of solvent, the crystal in biodiesel can be made to be separated out with more tiny crystal form, so as to improve life
The low temperature flow of thing diesel oil.

Pour point reducer composition is with blending oil quality than 1 in embodiment 4:100 depression effeCt is more preferably.
Embodiment 5
The pour point reducer composition of a kind of biodiesel-petrifaction diesel blending oil, by repefral, O-phthalic
Diethyl phthalate, dibutyl phthalate, butyl acetate and pour-point depressant mix, and calculate by mass percentage, its raw material group
Into and content it is as follows：
Wherein described pour-point depressant is polymethacrylate pour-point depressant 10-320.
A kind of preparation method of the pour point reducer composition of above-mentioned biodiesel-petrifaction diesel blending oil, step are as follows：
Under normal temperature and pressure, by diethyl phthalate, repefral, dibutyl phthalate, acetic acid
Butyl ester and pour-point depressant are mixed by predetermined quality percentage, 20-25min, and ultrasonic disperse 25-30min are stirred at 40-50 DEG C, i.e.,
Obtain a kind of pour point reducer composition of biodiesel-petrifaction diesel blending oil.
A kind of pour point reducer composition of above-mentioned biodiesel-petrifaction diesel blending oil is mixed in biodiesel-petrifaction diesel
Applied in contaminated product, step is as follows：
Calculate by mass percentage, gained pour point reducer composition and biodiesel-petrifaction diesel blending oil are 1:100 ratio
Example calculates；Gained pour point reducer composition is added in biodiesel and petrifaction diesel blending oil, mixing is equal at normal temperatures and pressures
It is even and on processor for ultrasonic wave ultrasonic disperse 25-30min, be suitable for biodiesel-petrifaction diesel blending up to containing a kind of
The biodiesel at high proportion of the pour point reducer composition of oil-petrifaction diesel blending oil.
The soybean oil biology bavin of the pour point reducer composition containing biodiesel-petrifaction diesel blending oil of gained after tested
Oil -0#Petrifaction diesel blending oil (is calculated, soybean oil biodiesel by percent by volume：0# petrifaction diesels are 60%：40%)
Cold filter plugging point and pour point reduce by 9 DEG C and 8 DEG C respectively.
In conclusion a kind of pour point reducer composition of biodiesel of the present invention-petrifaction diesel blending oil, contained therein
Diesel pour inhibitor plays main pour-point depressing process, contained diethyl phthalate, repefral, phthalic acid two
Butyl ester and butyl acetate not only primarily serve the effect of dilution diffusion, reduce the viscosity of pour-point depressant, and increase pour-point depressant is blending
Dissolubility in oil, makes pour point reducer composition be dispersed in blending oil, but also is cooperateed with the same time together with pour-point depressant, so that
Further enhance depression effeCt.Add it to by soybean oil biodiesel and 0#In petrifaction diesel blending oil, gained contains
Soybean oil biodiesel -0# petrifaction diesels blending the oil of the pour point reducer composition of biodiesel-petrifaction diesel blending oil at high proportion
Cold filter plugging point and pour point reduce 7-11 DEG C and 6-10 DEG C respectively.It is to by soybean oil biodiesel and 0 at the same time#Petrifaction diesel blends
The sensitivity of oil is more preferable, better than commercially available pour-point depressant.
The above is only the basic explanation under present inventive concept, and is done according to technical scheme any etc.
Effect conversion, is within the scope of protection of the invention.
