Description
Technical field
The present invention relates to a kind of low-sulfur diesel-oil compositions of additives that contains biological enzyme, belong to the diesel-dope technical field.
Background technology
Diesel oil had not only acted as a fuel but also, as the lubricant of transfer pump and injection pump,, if the oilness of diesel oil is bad, just can't cause reduce work-ing life for oil pump provides lubricated reliably in engine, may cause the oil pump leakage of oil when serious.
In the past less demanding to the refining depth of diesel oil, the oilness problem does not appear in diesel oil.In recent years, along with environmental protection is more and more higher to the diesel quality requirement, in diesel oil, sulphur content has been subject to strictly controlling, and the oilness problem of diesel oil comes out gradually.Diesel fuel lubricity Performance Assessment Test result shows, most of Lubricity of Low-Sulfur Diesel Fuels are very poor, and sulphur content just may make engine wearing and tearing occur less than the diesel oil of 500 μ g/g.And the sulphur content of the Europe IV standard regulation diesel oil that will implement in 2005 can not be greater than 50 μ g/g, and world's fuel oil standard IV class standard stipulates that even the sulphur content of diesel oil can not be greater than 10 μ g/g.Therefore, lower sulfur diesel will become the inexorable trend of following derv fuel oil development, but the oilness problem of the low-sulfur that thereupon causes or ultra-low-sulphur diesel should cause enough attention.At present, the mean content of sulfur of China's diesel oil is still very high, and the oilness of diesel oil does not also become large problem in a short time, but diesel oil standard has been trend of the times to international joint, about the problem of Lubricity of Low-Sulfur Diesel Fuels, must prevent trouble before it happens.
As far back as eighties of last century eighties, the light equality of Wei was just carried out a large amount of research for the diesel fuel lubricity problem, thought that the oilness of diesel oil depends primarily on the content of polar impurity.These polar impurities can generate high-resistance protective membrane, thereby effectively reduce wearing and tearing.The light flat model compound that also utilizes of Wei has been studied the impact on its oilness of aromatic hydrocarbons in diesel oil, oxygen carrier, nitrogenous substances, S-contained substance, think that the Relationship of Wear of mononuclear aromatics in diesel component and double ring arene content and diesel component is little, and polycyclic aromatic hydrocarbons, nitrogenous compound, oxygenatedchemicals all has good wear-resistant effect.Sulfide is not only not wear-resistant, and promotes wearing and tearing.Low-sulfur diesel-oil why poor lubricity is because the sulfide in diesel oil is present in aromatic hydrocarbons and polycyclic aromatic hydrocarbons mainly with the heterocycle form, has also removed aromatic hydrocarbons with lubricity and polycyclic aromatic hydrocarbons when removing sulfide and other has the component of oilness.
Main by adding slip additive to improve the oilness of low-sulfur diesel-oil in prior art, slip additive commonly used mostly is the derivative of lipid acid and ester, acid amides or salt; Research shows that biofuel can also improve the oilness of low-sulfur diesel-oil, and patent document CS275894 discloses with natural fats and oils such as rapeseed oil, sunflower oil, castor-oil plant wet goods directly as diesel antiwear additive; But the above-mentioned approach that improves Lubricity of Low-Sulfur Diesel Fuels far can not meet the demand of engine to Lubricity of Low-Sulfur Diesel Fuels, is badly in need of a kind of additive that can significantly improve Lubricity of Low-Sulfur Diesel Fuels of exploitation and improves its oilness.
