Description
Technical field
The invention belongs to derived energy chemical field, relate to a kind of biofuel pour point depressant, be specifically related to a kind of additive reducing biodiesel congealing point and cold filter clogging temperature.
Background technology
Along with the change of world energy sources structure and the raising of environmental requirement, the problems demand such as petroleum resources are in short supply, environmental pollution and Greenhouse effect solve, current many national research institutions are all at active research development environment friendly, the green energy resource that can extensively promote the use of, and biofuel was paid much attention in recent years.
Adopt the waterplant greases such as oil crops, Wild oil plant and engineering microalgae and animal grease, waste cooking oil etc. to be stock oil, the fatty acid methyl ester obtained by ester exchange process or ethyl ester fuel are biofuel.As substitute of diesel fuel, be typical " green energy resource " (Xing Ying, Xi Yijia. the production status of biofuel and development prospect. Guangdong chemical industry 2006:6-9.).Biofuel and petrifaction diesel similar nature, directly can use in the engine using diesel oil, and do not need to transform engine, storage condition condition is the same with petrifaction diesel, biofuel burning liberated heat and the similar petrifaction diesel of its ratio of carbon-hydrogen close.Compared with petrifaction diesel, biofuel has following advantage: the quantity discharged of the hydrocarbon polymer, carbon monoxide, sulfurous gas, aromatic compound, unburned hydrocarbons and the particulate matter that use biofuel to produce is all low than petrifaction diesel, substantially (plum Deqing is produced without sulfurous gas, Yuan Yinnan, grandson's equality. Light-duty Vehicle uses the research of biofuel transient condition emission performance. automobile engineering .2007:117-120.); Biofuel itself can biological degradation environmental sound, and can promote crude oil and coal tar biological degradation (Zhang Tian, Yuan Yinnan. the environmental benefit of biofuel and economic results in society. energy environment protects .2005:16-19); Because photosynthesis carbon is recycled, can not cause Greenhouse effect (Wang Lin, Wang Weiqiang. reduce the biofuel of environmental pollution. World Science, 1995:48.); Flash-point exceeds about 70 DEG C than petrifaction diesel, has high security, store and transport all very safe (Hu Zhiyuan, Tan Buqiang, Lou Di are bright. the Study on Physico-chemical of biodiesel-diesel mixed fued. oil engine, 2006:39-42.); Biofuel can also super fatting agent effect, alleviates the wearing and tearing of engine, extends its work-ing life.
Because biofuel has above-mentioned advantage, with the obvious advantage in petroleum replacing fuel, but the biofuel that some raw materials are obtained does not at present reach 0
#,-10
#,-20
#the service index of diesel oil.Such as low-temperature fluidity is exactly one of diesel oil using property data, the main component of biofuel is mixed methyl aliphatic ester, low-temperature fluidity comparatively petrifaction diesel is poor, use easily blocking diesel motor pipeline and strainer at Cold Winter, so just limit its application under low temp area or cold condition.
Summary of the invention
According to above-mentioned weak point, the object of the invention is a kind of formula of biofuel pour point depressant.
Know-why of the present invention
