Abstract
The present invention discloses synthetic diesel oil, which uses three principal components of desulphurization heavy benzol as major raw material, a proper amount of coal and light diesel oil. Small amounts of cetane number improver, viscosity index improver, flow property improver, etc. are mixed in the three main components. The present invention has the advantages of high cetane number, good starting performance, high heat of combustion, strong break-out force, high power, low oil consumption, simple preparation technology and equipment, wide source of raw materials, low cost, etc.
Description
Technical field
The present invention relates to a kind of diesel oil, particularly relate to a kind of combined diesel oil.
Background technology
The vehicle fuel oil that China produces can only the supply requirement amount 60%, all the other 40% rely on imports to come the alleviation demand.Be subjected to the restriction of petroleum resources, the fuel in oil source can not satisfy the needs of machine, car development far away.So the development fuel substitute is promoted economic development to replenishing the oil product deficiency, has energy-conserving and environment-protective and economic worth.General diesel oil or only be applicable to extremely frigid zones, or only be applicable to general area does not have a kind ofly not only to be applicable to extremely frigid zones but also be applicable to general geographic diesel oil.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can and can be applicable to extremely frigid zones and general geographic combined diesel oil as fuel substitute.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: by the desulfurization heavy benzol is main raw material, add an amount of kerosene, solar oil mixes a spot of cetane number improver, viscosity index improver, flowing property improving agent etc. again as three kinds of main components and mixes, and its preparation scheme is:
The component title is content % by weight
1. heavy benzol 40～70
2. solar oil 25～45
3. cetane number improver 2～8
4. viscosity index improver 1～3
5. the flowing property improving agent 1～4
6. ferrocene 0.05～0.2
Get the liquid of carrying in 170～300 ℃ of boiling ranges in byproduct crude benzol that above-mentioned main component desulfurization heavy benzol is refinery and coke-oven plant or the tar, add-on is 30～65%.
A kind of in the scheme in the used optional free alkyl nitrate ester selected of cetane number improver, add-on is 2～8%.
Optional a kind of in poly-methyl acrylate, polyisobutene, polyacrylic ester of used viscosity index improver in the scheme, add-on is 1～3%.
A kind of in the scheme in the used optional autohemagglutination ethylene-vinyl acetate of flowing property improving agent, long chain alkyl naphthalene, the long chain alkylphenol, add-on is 1～4%.
As another embodiment of the invention, can in above-mentioned component, add cracking kerosene.
The present invention program comprises 16 of colourity, sulphur content, acidity, moisture content etc. through quality examination, and every index all meets No. 0 ,-No. 10 diesel oil standards in the GB252-2000 solar oil, sees the following form:
