Description
Technical field
The present invention relates to state-of-the-art technology in the exploitation of alternative synthetic lubricant to adapt to the remarkable reduction of sulphur content in super low sulfur and low sulphur diesel fuel.
Background technology
In several past years, diesel oil fuel suffers environmental stress significantly reduce to make lubrication key element (sulphur) or eliminate always.In the fuel system of diesel motor, sulphur plays a major role for lubricating mechanical components.From on October 15th, 2006, EPA proposed except California and remote Alaska, and the new standard of the sulphur content of the diesel oil fuel of setting out on a journey that the U.S. sells is that ultralow diesel oil fuel is only for the sulphur containing 15PPM.From on September 1st, 2006, this standard was just carried out in California, and remote Alaska also will make all diesel oil be converted to ultra-low-sulphur diesel before 2010.New regulation is applicable to the distillate fuel of all diesel oil fuels and diesel fuel additive and institute's blending, and is applicable to the diesel oil used of setting out on a journey, such as kerosene.To on December 1st, 2010, all highway diesel oil will be all ultra-low-sulphur diesel.Non-road diesel oil will be converted to the sulphur (low-sulfur diesel-oil) of 500PPM in 2007 and will be converted to ultra-low-sulphur diesel by 2010.Also will be converted to the sulphur of 500PPM at trains in 2007 and ship diesel oil, and be converted to ultra-low-sulphur diesel by 2012.Before in October, 1993, the sulphur content in diesel oil fuel is 5000PPM, and this makes it possible to have enough lubrications to moving parts such as petrolift, injector and valve etc.Along with the remarkable reduction of sulphur, decrease necessary lubrication and reduce thus make premature abrasion become a large problem in diesel oil mechanical industry.
Summary of the invention
The invention discloses a kind of diesel oil fuel lubricant as the substitute of sulphur lubrication in super low sulfur and low sulphur diesel fuel, produce the method for described lubricant, and use the method for described lubricant.This lubricant contains alpha-olefin, low smell aromatic solvent and at least one and is selected from base oil in the base oil group be made up of the senior base oil of hydroisomerization and the violent hydrocracking base oil of HT and other composition.Also disclose a kind of method of producing this lubricant.
Embodiment
The present invention relates to the purposes of a kind of diesel oil substitute fuel lubrication additive for super low sulfur and low-sulfur diesel-oil, it can join the remarkable reduction substituting usually relevant to higher sulfur content in diesel oil fuel lubrication in fuel.This product can be used in diesel motor that sulphur is the form of ownership of the necessary component of internal lubrication and steam turbine.The present invention openly submits to EPA by secret, and receives number of registration in October, 2007 according to 40CFR79.23.
Diesel fuel additive in the past depends on the high density sulphur consumption in diesel oil fuel, and this has been subject to the strict restriction of Environmental Protection Agency and each Overseas Government now.For new international environment standard, the sulphur in diesel oil is restricted to 15PPM for application of setting out on a journey.In some ship and train transport, in the process to ultra-low-sulphur diesel transition, have approved the 500PPM of finite time.
Main component
Finished product (the preferred embodiments of the invention) is the combination of following composition:
● alpha-olefin: this is a kind of main component, it is also referred to as alkene, polyaluminium vasoliniment, and clorafin, its carbon chain lengths is 12-24, and the weight percentage of chlorine is 21.4%-70%, HCl is 4-10ppm and molecular weight is 273.5-650, and Cl (2) weight fraction is 20-70%, the proportion at 25 DEG C is 1.050-1.50, and the JQD weight percentage of HCL is 0.20-0.60.The main application of this composition is for lubricant formulations, lubricant additive compound, extreme-pressure additive formula and intermetallic composite coating compound.In addition when alpha-olefin and related products thereof decrease the accumulation of aging or excessive water in fuel algae growth and make fuel long-time stable, and simultaneously for the combustion chamber of fuel system and engine provides extremely lubrication.This provide the lubrication lacked in ultra-low-sulphur diesel.
● low smell aromatic solvent: this is main component, it is a kind of highly refined low toxicity, low smell solvent, ideally for japanning, varnish, food-grade coating, tackiness agent, thinner, thinner, agrochemicals, domestic pesticide, spray oil and specialty chemicals.Aromatic hydrocarbons percentage ratio is 5-40%(EC-A-G04), flash-point is 20 to 80 DEG C (ASTMD-93) and 30 DEG C of (+/-) lower densities are 0.600-0.900(ASTMD-4052).
● the senior base oil of hydroisomerization and the violent hydrocracking base oil of HT: this main component a kind ofly has low or do not have violent hydrocracking or the hydroisomerizing base oil of aromatic hydrocarbon and impurity, heavy many rings paraffin molecule to reduce or remove the polar compound of sulfur-bearing, nitrogen and oxygen and aromatic hydrocarbon is converted into saturated rings alkane by raw material and hydrogen generation chemical reaction, thus is split into light stable hydrocarbon and obtains by it.This can comprise the distillate through hydrofining or hydrogenation refining.This base oil can do the main body of lubricating oil, engine oil, machining oil, food-processing, medicine, industry, agricultural lubricants and extreme-pressure additive.These join in the lubrication of ultra low sulfur diesel fuel.
Other composition

Preferred blending equipment
This process sequence relates to a series of blending and holds tank, in accommodation tank, weighing products also can be pumped across control valve subsequently to maintain consistent flow and pressure.Blending should be carried out reducing product evaporation (loss) and preventing from being directly exposed to spark in closed tin.Blending equipment can be the combination of high speed or low speed blending equipment.The size and the volume that hold tank are not critical concerning blending.
Universal use of the present invention
Summarizing as follows, this product has carried out experiment test and verified when adding this product of 2-3 ounce in the super low sulfur of every 10 gallons or low-sulfur diesel-oil in different kinds of roads or off roader, achieving that wearing and tearing reduce, mileage number increases and discharge reduces.
Test procedure
Fresh approach for super low sulfur and low sulphur diesel fuel test wear is high-frequency reciprocating experimental machine (HFRR).ASTM-D975。Fuel carries out wear testing and must show the polishing scratch being not more than 520 microns.
Test result
Although all diesel oil fuels after tested have all exceeded the wearing and tearing of allowing reach 20-30 micron, additive of the present invention is joined ultra-low-sulphur diesel (every 10 gallons of diesel fuel fuel 2.0 ounces) polishing scratch is reduced allow scar size about 28% or about 375 microns.
This experiment test demonstrates the present invention significantly can reduce the wearing and tearing that current diesel oil mechanism bears.Along with the further test ASTM standard developed with regard to ultra-low-sulphur diesel, further experiment test will be carried out to the present invention.
Although illustrate only preferred features more of the present invention here, a lot of amendment, change and replacement are known to those skilled in the art.Therefore, be understood that claims are intended to cover all modifications and variations fallen in connotation of the present invention.
