Description
Technical field
Present invention relates particularly to a kind of polyol class biodiesel pour point reducer compositions and preparation method thereof, belong to biomass energy
Source additive technical field.
Background technique
Biodiesel refers to that, by ester exchange reaction, the alcohols such as animal and vegetable oil and methanol, ethyl alcohol are the rouge that raw material obtains
Fat esters of gallic acid mixture.Early in the eighties in 19th century, Germany scientist, which becomes function research and development and converts one for dish son's oil, to plant vegetables young oil
Biodiesel.Biodiesel is studied since the beginning of the nineties in last century, as reproducible green, environmental protection, bio-fuel
Through causing the extensive concern mouth of domestic and international researcher, and various aspects are carried out about the research of biodiesel and in American-European state
Family is own to form large-scale production.Currently, feedstock oil needed for biodiesel preparation mainly includes oil crops, vegetable oil and animal
Grease etc..Compared with these feedstock oils, as a big country using edible oil, waste oil from restaurants (gutter oil) conduct is chosen
Feedstock oil prepares biodiesel, it appears particularly important.It both can avoid the generation of " striving grain with people, strive ground with grain " phenomenon in this way, again
It can avoid criminal that gutter oil is come back to dining table well, to constitute a threat to human health.
Biodiesel has many advantages compared with petrochemical diesel fuel；Firstly, the raw material of preparation biodiesel is renewable
Feedstock oil can effectively alleviate oil crisis if promoted and applied, while it has good degradability；Its
Secondary, biodiesel is nontoxic, and sulfur content is low after burning, to environmental beneficial.But when biodiesel at 0 DEG C or so in use, by
Crystallization is easy in fatty acid methyl ester therein to be precipitated, will cause filter and the oil transportation pipe choking of engine, and then influences to start
Machine works normally.Therefore, the ameliorative way for studying biodiesel lower-temperature fluidity, be biodiesel be able to the factor promoted it
One.
Suitable pour-point depressant, that is, cold flow improver is added in biodiesel, the knot of change biodiesel can be passed through
Brilliant behavior inhibits the growth of crystal and aggregation effectively, and then can improve its low temperature flow.Alcohols such as methanol,
Ethyl alcohol, propyl alcohol etc. have a very low boiling point, on the one hand can be with usually at subzero 50 DEG C hereinafter, when it is added in biodiesel
Its cold filter plugging point, condensation point are reduced, on the other hand pour-point depressant can also be made to be better dispersed in biodiesel, reach and preferably drop
Solidifying effect.
Summary of the invention
An object of the present invention is to provide a kind of polyol class biodiesel pour point reducer composition, and the composition can be effective

The second object of the present invention is to provide a kind of preparation method of above-mentioned polyol class biodiesel pour point reducer composition,
Keep the development of pour-point depressant more diversified.
Technical solution of the present invention is specifically described as follows.
A kind of polyol class biodiesel pour point reducer composition, raw material are calculated by mass percentage, and each component and content are such as
Under:
Wherein, the biodiesel pour-point depressant is polymethacrylate pour-point depressant 10-310.
In the present invention, the raw material of composition is calculated by mass percentage, and each component and content are as follows:
Wherein, the biodiesel pour-point depressant is polymethacrylate pour-point depressant 10-310.
The present invention also provides a kind of preparation methods of polyol class biodiesel pour point reducer composition, the specific steps are as follows:
By each raw material mix after, 45~55 DEG C of water bath with thermostatic control at a temperature of carry out 40~80min of ultrasonic disperse to get one
Kind polyol class biodiesel pour point reducer composition.
Compared to the prior art, the beneficial effects of the present invention are:
A kind of polyol class biodiesel pour point reducer composition of the invention, due to being to mix alcohols with pour-point depressant and form
Biodiesel pour point reducer composition, i.e., cold filter plugging point and condensation point are reduced by alcohols solvent, pour-point depressant can be increased in diesel oil
In solubility, improve its dispersion in diesel oil, be better dispersed in it in diesel oil, the two complements each other, jointly
The low temperature flow for improving diesel oil further enhances its depression effeCt.It is used in biodiesel, can effectively drop
Its low cold filter plugging point and condensation point can make cold filter plugging point reduce by 15~20 DEG C, and condensation point reduces by 26~33 DEG C, significantly improves biology
The low temperature flow of diesel oil.
