Abstract

A kind of high-octane lead-free synthetic gasoline is a main raw material with methyl alcohol, cooperates other composition to mix, and directly gasoline replacing is used for various vehicles, has anti-knocking property, all good and little characteristics of pollution of security, stability.Its making method is simple, easily promotes.

Description

High-octane lead-free synthetic gasoline and preparation method thereof

The present invention relates to petrochemical industry, a kind of preparation method of New-type fuel-high-octane lead-free synthetic gasoline.

The fuel of present various transport facilitys, all gasoline, diesel oil to go out from petroleum refining.People often stand energy-intensive danger, estimate the later stage nineties, oil will be more nervous, in addition, no matter gasoline, diesel oil all exist problem of environmental pollution, therefore, develop a kind of new synthol, serve as gasoline and use,, be absolutely necessary in order to alleviate energy shortage and to reduce environmental pollution.

The present invention promptly is a kind of high-octane lead-free synthetic gasoline of inventing at the problem of existing gasoline existence.It can directly apply to various vehicles, good anti-knocking property, chemical safety physical stability is arranged and pollute little characteristics.

The present invention is main raw material with methyl alcohol, by weight its each composition be: methyl alcohol 42～52%, virgin oil 16～20%, cracked oil 18%～25%, distilled water 5～8%, condensate oil 0.5%～3%, peroxidation zinc powder 3～5%, rosin 1～3%, acetone 1～5%, commercial gasoline 10～20%, emulsifying agent 0.5～3%.Here, emulsifying agent is to be mixed by tween (twen) and department this (span).

The concrete compound method of this synthetic gasoline is: the octane value of gasoline is determined the accurate ratio of each composition according to joining, preparation by the following method: the first step, with distilled water and emulsifier mix, stirring adds commercial gasoline again, after fully being stirred to dissolving fully, add methyl alcohol more slowly; Second step was with all the other raw material virgin oils, and cracked oil, condensate oil, peroxidation zinc powder, rosin, acetone add successively while stirring.After treating that whole raw materials finish, fully stirred again 0.5～1.5 hour, at last after filtration.

The present invention has solved current gasoline anxiety, problem of environment pollution caused preferably as the surrogate of gasoline.Because this synthetic gasoline is not leaded, so fundamentally solved Lead contamination, this synthetic gasoline has good anti-knocking property, chemical safety, physical stability.Vehicles such as passenger-cargo automobile, car, motorcycle are not increasing and are reequiping under the prerequisite of any parts, and thermo-efficiency improves more than 5%, have easily simultaneously start, the No oxidation corrosion phenomenon.After tested, when various vehicles used, the CO that is discharged and other obnoxious flavour reduced about 20～30% than 70# commercial gasoline, and price reduces about 20～30% than present commercial gasoline.

The various indexs of this synthetic gasoline are compared as follows with the commercial gasoline quality index:

Classification quality index measured result

1, water soluble acid or alkali nothing

2, corrodibility (50 ℃ of 3h of copper sheet) is qualified

3, mechanical impurity % is not more than does not have

4, moisture content (%) is not more than does not have

5,10% recovered temperature ℃ is not higher than 79 64

6,50% recovered temperature ℃ is not higher than 145 105

7,90% recovered temperature ℃ is not higher than 195 155

8, do and ℃ be not higher than 205 215

9, residue and loss amount % are not more than 4.5 2

10, residual amount % 1.5 1.5

Synthetic gasoline with synthetic suitable 70# gasoline is an example below, detailed each composition of this synthetic gasoline that is listed as:

Methyl alcohol: 42%; Virgin oil 18%; Cracked oil 22%;

Distilled water: 5%; Condensate oil 1%; Peroxidation zinc powder 4%;

Rosin: 1%; Acetone 1.5%; Emulsifying agent 0.5%;

Commercial gasoline 5%.

More than each composition by promptly getting this high-octane lead-free synthetic gasoline after the matching method proportioning of the present invention.

Claims

1, a kind of high-octane lead-free synthetic gasoline, it is characterized in that composition of the present invention is: methyl alcohol 42～52%, virgin oil 16～20%, cracked oil 18～25%, distilled water 5～8%, condensate oil 0.5～3%, peroxidation zinc powder 3～5%, rosin 2～3%, acetone 2～5%, commercial gasoline 5～20%, emulsifying agent 2～3%.

2, a kind of high-octane lead-free synthetic gasoline as claimed in claim 1 is characterized in that emulsifying agent is to be mixed by tween (twen) and department this (Span).

3, a kind of compound method of high-octane lead-free synthetic gasoline is characterized in that: the first step stirs distilled water and emulsifier mix commercial gasoline to be put into again, and fully is stirred to fully to add methyl alcohol more slowly after the dissolving; Second step added all the other raw material virgin oils, cracked oil, condensate oil peroxidation zinc powder, rosin, acetone successively while stirring, fully stirred again 0.5～1.5 hour after all raw material adds, at last after filtration, each adds the ratio of composition, be as the criterion with the described ratio of claim 1.
