A kind of low-sulfur ordinary diesel oilTechnical field
The present invention relates to clean energy technology field more particularly to a kind of low-sulfur ordinary diesel oils.
Background technique
GB17411-2015 bunker fuel oil D group distillate fuel oil, sulfur content minimum 0.1% have been not suitable with increasinglyStringent environmental regulation, GB252-2015 ordinary diesel oil standard are executed from 2 months 2018 sulfur contents by < 10PPM.To reducePollution to environment and new standard is adapted to it is necessary to improve to existing diesel oil, use comprehensive performance to improve it.
Diesel fuel lubricity Performance Assessment Test the result shows that, most of Lubricity of Low-Sulfur Diesel Fuels are very poor, and sulfur content is less than 500 μThe diesel oil of gg-1 may will lead to engine and wear, and with the intensification of low state of cure (vulcanization), diesel fuel lubricity performance is moreDifference.With the continuous renewal of laws and regulations, manufacturing enterprise must not take no action to improve diesel oil abrasion resistance.Mainly takeMeasure has following 3 kinds: 1. controlling diesel oil hydrogenation depth as much as possible, retains the excellent component of lubricity；2. being mixed into high lubricationProperty diesel component, while meet sulfur content requirement；3. adding improver for lubricating performance of low-sulfur diesel oil (the also referred to as wear-resistant addition of diesel oilAgent).Wherein, be added diesel oil wear resistence additive (hereinafter referred to as antiwear additive) be widely used at present be also it is most effectiveMethod.But 1. existing diesel fuel lubricity agent influences the cold filter plugging point of diesel oil；2. can be because of the poor solubility in diesel oil in low temperatureAnd be precipitated, diesel oil is become cloudy, low-temperature storage stability is influenced；Match 3. there are organic acid type antiwear additives with engine lubricating oil5 property difference problems；Ester type antiwear additive occurs influencing oxidation stability of diesel oil, low temperature flow phenomenon, the influence bavin also having oftenOily Cetane number, or even there is sediment and lamination.
Summary of the invention
The purpose of the present invention is to solve the higher problems of conventional diesel sulfur content, and a kind of low-sulfur proposed is commonDiesel oil, and its greasy property is further improved, and good fluidity at low temperature, stable storing, with diesel oil detergent, tenSix alkane value modifier long stable effects coexist.
To achieve the goals above, present invention employs following technical solutions:
The raw material including following parts by weight: a kind of low-sulfur ordinary diesel oil adds normal 400~600 parts by weight of bavin of hydrogen, hydrogen is added to urge300~400 parts by weight of bavin, 75~125 parts by weight of aviation kerosine, 2~5 parts by weight of tert-butyl hydroperoxide, polyetheramine 0.2~0.5 parts by weight.
Preferably, described plus normal 500 parts by weight of bavin of hydrogen, add hydrogen to urge 400 parts by weight of bavin, 96 parts by weight of aviation kerosine, tertiary fourth4 parts by weight of base hydrogen peroxide, 0.4 parts by weight of polyetheramine.
Preferably, described plus normal 500 parts by weight of bavin of hydrogen, add hydrogen to urge 350 parts by weight of bavin, 125 parts by weight of aviation kerosine, uncle3 parts by weight of butylhydroperoxide, 0.4 parts by weight of polyetheramine.
Preferably, described plus normal 400 parts by weight of bavin of hydrogen, add hydrogen to urge 400 parts by weight of bavin, 96 parts by weight of aviation kerosine, tertiary fourth3 parts by weight of base hydrogen peroxide, 0.4 parts by weight of polyetheramine.
Preferably, described plus normal 600 parts by weight of bavin of hydrogen, add hydrogen to urge 300 parts by weight of bavin, 96 parts by weight of aviation kerosine, tertiary fourth4 parts by weight of base hydrogen peroxide, 0.4 parts by weight of polyetheramine.
Preferably, the low-sulfur ordinary diesel oil still further comprises the raw material of following parts by weight: oleic acid glycol ester 5-8Part, 2 parts of castor oil methyl esters, 0.5 part of epoxidized soybean oil.
When additional amount is low, wear scar diameter does not change significantly oleic acid glycol ester, and lubrication improvement is unknownIt is aobvious and unstable under low temperature.
Epoxidized soybean oil abbreviation ESO, -8 DEG C of freezing point, is dissolved in alkane and most of organic solvents, is slightly soluble in water, volatilizationProperty is small, migration is low, heat resistance, light resistance, weatherability are excellent, also unstable under low temperature.
The low temperature flow of castor oil methyl esters is very poor.
The present invention compounds oleic acid glycol ester and epoxidized soybean oil, castor oil methyl esters under certain proportion, and appliesIn low-sulfur ordinary diesel oil of the invention, it can be effectively improved the lubricity of low-sulfur diesel-oil, and unexpectedly, lowMobility and stability under temperature is fine.
The invention also provides a kind of preparation methods of low-sulfur ordinary diesel oil, comprising the following steps:
S1: all raw materials being put into and are adjusted in oil tank, is uniformly mixed with gear pump through static mixer, is obtained solution A；
S2: after solution A filter screen filtration, low-sulfur ordinary diesel oil is obtained within static 24 hours.
Preferably, the dimensional parameters of the filter screen are 400 mesh.
Compared with prior art, the beneficial effects of the present invention are:
The present invention can effectively reduce the sulfur content in diesel oil, can be used for distillate fuel oil peculiar to vessel, and engineering machinery is draggedMachine drawing, generator diesel oil boiler etc. greatly reduce pollution, have the good feature of environmental protection, meanwhile, preparation process letter of the present inventionSingle, rationally, economic benefit is very good.Meanwhile it being effectively improved the lubricity of low-sulfur diesel-oil, and unexpectedly, in low temperatureUnder mobility and stability it is fine.
