Abstract
The present invention discloses one kind of diesel oil pour point reducer, which consists of alpha-olefin 5-15 wt%, acrylate 15-30 wt%, maleic anhydride 20-45 wt%, fatty amine 10-25 wt%, and alkyl naphthalene 20-50 wt%. The diesel oil pour point reducer is used mainly for adding into 0# diesel oil so as to improve it into -10# diesel oil. Practical application shows that it has the excellent performances of high storage safety with flash point up to 70 deg.c or so and high pour point reducing effect.
Description
Technical field
The present invention relates to a kind of pour point depressant, particularly a kind of pour point depressant that is used for diesel oil.
Background technology
In industries such as the energy, traffic, diesel oil occupies important status.Especially No. 0 diesel oil accounts for more than 70% of diesel oil total amount.No. 0 a diesel oil outstanding problem in use is that low-temperature fluidity is poor.Particularly on the south the Changjiang river, diesel oil uses in the winter time because of the cloud point height causes the engine oil deficiency, directly influences the works better of engine.In recent years, the price of gasoline, diesel oil is constantly soaring, uses winter-No. 10 diesel oil not only to increase fuel cost, also often is subjected to the puzzlement of resource anxiety.
The domestic additive that is used for improving the diesel oil at low-temperature performance is used widely at-20 ,-No. 35 diesel oil.But for No. 0 diesel oil, additive effect is not satisfactory.Better to cycloalkyl diesel oil effect, relatively poor to paraffinic base.Major cause is a wax content height in No. 0 diesel oil, and cut is wide.
U.S. Exxon company has at first developed this diesel pour inhibitor in 1985.Subsequently, IFP, German Clariant company and Japanese Sanyo company develop dissimilar agent for improving flowability of diesel oil in succession.Up to the present, the compound problem of diesel oil turbidity removal agent and diesel oil at low-temperature fluidity improver and the consumption problem of additive in diesel oil are not appeared in the newspapers always.
China has run into some problems when exploitation is fit to the pour point depressant of No. 0 diesel oil:
(1) chemical constitution of diesel oil, fraction are relatively more responsive to additive response.Find rational blending combination, just can reach satisfied additive effect.Many external pour point depressants are improper to the susceptibility of the diesel oil of China, can't reach the pour point depression effect.
(2) vast territory and abundant resources according to China, and diesel oil chemical constitution and fraction are different, can be different to the adaptability of pour point depressant, solve the widely applicable problem of wide spectrum.
(3) the diesel pour inhibitor flash-point belongs to the one-level hazardous substance about 30 ℃ usually, does not possess the practical situation of storing dangerous product according to most of user.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of diesel pour inhibitor, to overcome above-mentioned defective and the problem that prior art exists.
Diesel pour inhibitor of the present invention, its composition and amount per-cent are composed as follows:
Alpha-olefin 5～15%
Acrylate 15～30%
Maleic anhydride 20～45%
Aliphatic amide 10～25%
Alkylnaphthalene 20～50%
Be more preferably:
Alpha-olefin 8%
Acrylate 19%
Maleic anhydride 29%
Aliphatic amide 14%
Alkylnaphthalene 30%
The alpha-olefin of the preferred C15～C20 of said alpha-olefin;
The aliphatic amide of the preferred C15～C20 of said aliphatic amide hydrocarbon;
The alkylnaphthalene of the preferred C15～C20 of said alkylnaphthalene.
The preparation method of diesel pour inhibitor of the present invention is a kind of physical mixed method of routine, each raw material stirring is mixed getting final product.
Diesel pour inhibitor of the present invention mainly is applicable to be added in No. 0 diesel oil and makes it to be improved to diesel oil-No. 10, uses through example, has following excellent properties.
(1) the storage safe performance is good
Usually the diesel pour inhibitor flash-point belongs to the one-level hazardous substance about 30 ℃, according to the practical situation that most of enterprise does not possess storing dangerous product, determines that the pour point depressant flash-point is not less than 55 ℃.Through adjusting repeatedly and testing, developed the pour point depressant of safety type, the flash-point of representative data reaches about 70 ℃, obviously is better than like product both domestic and external.
(2) pour point depression is effective
This product joins Zhenghai, He Jiawan, Qixia Mountain, gold and defends in No. 0 diesel oil in west, through third party feeler mechanism analytical test, effect with tangible reduction cold filter point of diesel oil can find out that diesel pour inhibitor of the present invention has the effect of very excellent reduction cold filter point of diesel oil from the test data contrast.
Embodiment
Among the embodiment, alpha-olefin, aliphatic amide and alkylnaphthalene are 18 carbon atoms.
