A kind of compound diesel additive and preparation method thereof
Technical field
The technical field that the invention belongs to fuel oil additive, is specifically related to a kind of compound diesel additive and preparation method thereof.
Background technology
The height of fuel qualities is all extremely important to fuel oil consumption, exhaust emissions, performance.Current, also there is very big-difference in the fuel qualities of China, therefore compared with developed countries, in fuel oil, be necessary to add some additives, not only can well improve the performance of fuel oil, can also better meet economy, emission performance, the dynamic property of fuel oil, reach the effect of environmental protection and energy saving.As too low in the octane value of diesel oil, the label of conventionally saying is inadequate, can suitably add octane promoter; In fuel oil, add promoting agent, can remove the grease and the carbon distribution that are deposited on cylinder internal surface; Add catalytic type ignition dope, can make the burning of fuel oil complete at one time as far as possible, can effectively improve efficiency of engine etc., and, China is an oil importers, and prospective oil is very limited again, and a large amount of Imported oils threaten to the energy security of China, therefore, improve oil quality and concerning China, just more have realistic meaning.
At present, the output of China's fuel dope is very low, and its major cause is that the specification of quality of China's oil product is not high, adds many oil properties and depends on processing route.But along with raising and the raising of environmental protection to oil quality requirement of oil quality, fuel oil additive can develop to some extent.Now, various countries have formulated strict Abgasgesetz in succession, the discharge of restriction diesel vehicle obnoxious flavour.Therefore the oil consumption and the pollution that, further reduce diesel-engine road vehicle are current problem demanding prompt solutions.In numerous solutions, use the method for diesel-dope in the structure of not changing vehicle and engine, do not increase under the condition of equipment yet, by changing the physical property of fuel, make fuel be able to abundant burning, thereby realize energy-conservation and emission abatement.Therefore, the multi-functional compound diesel additive composition of exploitation fuel-economizing settling-discharging will more and more be subject to people's attention.
Summary of the invention
The object of the invention is to for the defect of above-mentioned existence and a kind of compound diesel additive and preparation method thereof is provided, this compound diesel additive can improve the performances such as the incendivity, spatter property, stability of diesel oil, effectively improve properties and the over-all properties of diesel oil, improve efficiency of combustion, reducing environmental pollution, is a kind of feature of environmental protection compound diesel additive of fuel-economizing settling-discharging.
