Abstract
The invention provides a preparation method for a highly-clean diesel oil cetane number improver. The improver is obtained by successively uniformly mixing and stirring the following substances in parts by mass: 60-70 parts of glycol dinitrate, 5-15 parts of amyl peroxy-2-ethylhexanoate, 5-15 parts of a cleaning dispersant, 5-10 parts of a cleaning agent, 5-20 parts of a stabilizing agent, and 1-2.5 parts of an antismoke agent. The highly-clean diesel oil cetane number improver is capable of effectively improving the cetane number of clean diesel oil and guaranteeing the cetane number stability of the clean diesel oil for a long time, is extremely high in cost performance, good in safety and simple in manufacturing technology, and is widely applicable to the field of highly-clean diesel oil.
Description
Technical field
The present invention relates to high-cleanness diesel oil additive agent field, particularly a kind of high-cleanness diesel oil cetane number improver.
Background technology
Oil is the important support of Economic development, at present, along with the aggravation of exploitation, the petroleum resources approach exhaustion of some high-qualitys, countries in the world crude oil heaviness phenomenon is more and more serious, straight run light constituent production of diesel oil day by day reduces, in order to solve problems, various countries generally adopt catalytic cracking secondary processing technique to improve the output of LIGHT DIESEL OIL, cause petroleum related products quality to change thereupon, the outstanding behaviours of diesel oil field be cetane value reduce, dynamic performance weakens.
At present, the cetane value of high-cleanness diesel oil is generally 38 ~ 45,45 are not less than with the ordinary diesel oil cetane value of national Specification, have certain gap, the cetane value therefore improving high-cleanness diesel oil is technical problem in the urgent need to address at present, by existing technical qualification, the corresponding measure that raising high-cleanness diesel oil cetane value is taked has: first, allocate with straight run LIGHT DIESEL OIL and use, but the output of straight-run diesel oil being very limited, is not long-range solution; The second, improve diesel-fuel cetane number by the method for hydrogenation, but high cost, be unfavorable for scale operation; 3rd, add cetane number improver, this mode is most economical and highly effective.Various countries have all dropped into a large amount of human and material resources and financial resources in the research and development of high-cleanness diesel oil cetane number improver, also quite outstanding achievement is achieved, to some extent solve the problem that high-cleanness diesel oil cetane value is low, but results and problems exists simultaneously.Now commercially there is the cetane number improver of many types, but general cost is too high, adds the difficulty of industrialization; On the other hand, the existing cetane number improver effect commercially existed is not too obvious, can only improve 3-5 on the original basis; In addition, existing cetane number improver leaded wastewater is higher, can increase the NO in emission in application process
x, produce photo-chemical smog, cause environmental pollution, this Ecoenvironment policy just with current is incompatible with.
Summary of the invention
Object of the present invention is just to provide a kind of preparation method of high-cleanness diesel oil cetane number improver, well solves that high-cleanness diesel oil cetane number improver production cost is high, DeGrain and the higher difficult problem of product leaded wastewater.
