Description
Technical field
The invention belongs to the technical field of fuel dope, be specifically related to compound octane promoter of a kind of white gasoline and preparation method thereof.
Background technology
It is relevant with fuel performance to a great extent that petrol engine produces pinking, if gasoline is very oxidizable, the superoxide of formation is difficult for decomposing, spontaneous ignition temperature is low, just be easy to occur phenomenon of detonation, so gasoline anti-knocking property are one of most important indexs of quality of gasoline, conventionally with octane value, weigh.The method of existing raising gasoline octane rating has 1: by refining of petroleum means such as catalytic cracking, reformation, alkylations; 2: the gasoline component of different octane is blended into together according to optimum ratio; 3: in gasoline component, add octane promoter.Wherein, first two method in actual applications, all exists problem, can not meet the requirement of people to quality of gasoline.Because the pinking in petrol motor is a kind of chain reaction, can in gasoline, add additive, reaction chain is interrupted, to improve the octane value of gasoline.Oneself is very extensive in the application of octane promoter in gasoline, in gasoline now used, except the model of particular requirement, has generally all added gasoline antiknock.Because its consumption is few, simple to operate flexible, successful, good economy performance, is to improve a kind of effective, the most most economical method of gasoline octane rating.
The effect that component is added in gasoline antiknock is to suppress combustion reactions automatically to accelerate, within the combustionvelocity of gasoline is limited in to normal range, before flame front arrives, suppress hydro carbons spontaneous combustion, the spontaneous combustion of unburned mixture body is extended inductive phase, or flame transmission speed is increased, reach the object of eliminating fuel knock burning.
Conventional unleaded antiknock agent has methyl cyclopentadiene three carboxyl manganese (being called for short MMT), methyl tertiary butyl ether (being called for short MTBE), ferrocene, tert amyl methyl ether(TAME) (being called for short TAME), the trimethyl carbinol (being called for short TBA), methyl alcohol, ethanol etc. at present.MTBE is generally used as gasoline dope in worldwide, it can not only effectively improve gasoline octane rating, and can also improve automotive performance, reduces content in exhaust, reduce gasoline production cost, but its use but easily pollutes to water resources simultaneously.Ferrocene is also to study at present more white gasoline octane promoter, but after gasoline and ferrocene burning, the ferric oxide of generation is easily deposited on the part of engine, is particularly deposited on petrolic sparking plug or in petrolic portfire.Methyl alcohol, the octane value of ethanol is very high, nor need other compared with macromolecular alcohol, to make cosolvent, can make processed oil octane value improve 2～3 units, but the cost of methyl alcohol and ethanol is higher, and their use is subject to certain restrictions, simultaneously when gasoline is moisture, can be separated, and the vapour pressure of methyl alcohol and ethanol is high, uses this improving agent to environmental protection and economic unfavorable.
Summary of the invention
The object of the invention is to for the defect of above-mentioned existence and compound octane promoter of a kind of white gasoline and preparation method thereof is provided, this kind of compound octane promoter of white gasoline not only can significantly improve gasoline octane value, improve gasoline combustion performance, and can effectively remove combustion residue, reduce exhaust gas emission.
