Description

i

The invention relates to petrochemicals, namely to a class of inventions based on hydrocarbons.

For economic reasons (saving fuel oil) and ecological (reducing the toxicity of the car's fuel) conventional gasoline is blended with alcohol or completely replaced (ΤθΡΘΗΤΒΒ Γ.Α. 272 c; TypeeB AA n αρ · Προμ3βοαοβο

BblCOKOOKTaHOBblX 6eH3MHOB.M, Xhmma, 1981. p.224). for this purpose, methanol, ethanol, the octane number of which is determined by the method of analysis, is 121-122. (Πρβ3ΘΛΜ M. BbicoKOOKTaHOBbie kmcaopoa-coAep * aiuMe κομποηθητ «aBT6eH3MHOB. - Hetjyrb, ra3 3a py6e * OM, 1989, N ° 9, p. 94-97)

Other high-octane oxygen additives are used to raise the octane of petrol without spirits: dicarbonic acids, their aldehydes, higher C4-C8 spirits, butyrals, butyrates, monoglycolic ethers. (TyPeeB A.A. M AP · riPOM3BOACTBO BblCOKOOKiaHOBblX 6βΗ3ΜΗΟΒ.-M., Χμμμβ, 1981-224).

In the case of propellant-blended petrol or pure spirits, the aldehyde content of the fuel is significantly increased (Milgrom Zionel. New Sci. - 1989, 122, No. 1659, p. 30). Heavy contamination of aldehydes is very harmful to the environment (eg, formaldehyde suspected of having carcinogenic effects in humans) accelerates engine and engine oil wear. By reducing this pollution in the engine, up to 5% water is added to the fuel.

However, the blend of petrol-spirits is flattened, so that even small amounts of moisture (in the presence of water in the starting materials in gasoline, spirits or accumulation of hydroscopic 2).

EN 3299 for humidity). Therefore, stable, stable petrol-alcohol blends suitable for the internal combustion engine are produced using stabilizers.

A properly selected stabilizer makes it possible to produce a transparent stable blend of petrol-spirits with as much as 5% of water impurities. (Tepernee Γ.Α. n., MoTOPHbi6 TonAMBa M3 aATePH0TMBHbix cbiPbeebix pecypcoB.- M., Χμμμη, 1989, 272 c;).

Ethanol is more common than methanol in blending the spirit additive with petrol, as the first one has better performance. Known U.S. Patent No. 4,554,186, which discloses a composition of a stable water-benzine-spirits fuel composition: 1-12% anhydrous or ethanol (water 0.35-0.44%) ethanol, 84-97% petrol and 2-4% stabilizer - isobutanol. The authors state a higher octane number of water-petrol-ethanol fuel compositions than petrol-anhydrous ethanol. The disadvantage of the solution is the use of expensive ethanol and isobutanol, which limits the practical application of this composition. The total amount of alcohol (ethanol + isobutanol) in fuel amounts to 16%, and the water additive is only 0.35 to 0.44%, so the engine will burn a lot of aldehyde in its fuel, so the proposed fuel composition is non-organic. Known EP Patent No. 0162122, which discloses a transparent, stable composition of water-benzine-ethanol fuel composition: ethanol (0.35-0.44% water), 1-12% by weight, 2-4% by weight stabilizer and 84-97% weight% unleaded petrol. The role of the stabilizer is: 1-butanol, 2-butanol, isobutanol, 2-methyl-butanol-1 and 3-methyl-butanol-1 (isoamyl alcohols), n-pentanol 3

LT 3299 B (amino alcohol). It has been found that 2-butanol, isobutanol, isoamyl and amyl alcohols have particularly good stabilizing properties.

The disadvantage of the solution is that the composition uses expensive purified food, suitable for the pharmaceutical industry. The stabilizer composition is complex and difficult to realize. All this limits the practical application of the proposed composition. The total amount of alcohol reaches 16% (ethanol + stabilizing spirits), while the water additive is just 0.35% to 0.44% using this fuel in the car's combustion engine. Therefore, the proposed fuel composition is non-organic. Known closest to the invention is the technical solution described in Polish Patent No. 273330 (prototype), which contains the composition of a stable water-benzine-ethanol composition: 6-20% by volume of technical benzene (component of automotive gasoline), 75-92% by volume of ethanol, 0, 1% by volume of water and 2-5% by volume of the stabilizer isobutanol fraction. The isobutanol fraction is an isobutanol that is not fully purified and is obtained from the fusion of isoamyl and amyl alcohol. The composition of the isobutanol fraction is 0.5-1.0% ethanol, 2-4% propanol, 0.2-0.5% 2-butanol, 94.2-97.2 - isobutanol.

The disadvantage of the solution is that expensive rectified ethanol, which forms the basis of the composition (75-92%), and the remainder -1 caroline gasoline, which is up to 15%, is used for its production. Benzene is a volatile substance with a high carcinogenic effect and is limited to 6% in car petrol in the EEC countries and 3% in the near future (The Gosoline and Diesel Market. IFP, 1988, p. 50). Cost of rectified ethanol and non-organic composition of fuel composition (unacceptable high 4

LT 3299 B benzene concentration) makes it practical, unrealistic application.

In addition, the appropriateness of the stabilizer (partially purified isobutanol) has been demonstrated for a limited range of ingredients (ethanol + one commercial gasoline hydrocarbon) and a narrow range of their ratios (the mixture is based on ethanol). Stabilizer-isobutanol fraction obtained by separating isoamyl and amyl alcohols from fusions with particularly good stabilizing properties (see EP patent No. 0162122). The remaining isobutanol has 2.8-5.8% impurities, spirits that do not have good stabilizing properties.

The ineffectiveness of isobutanol, which is fractions of isoamyl and amyl alcohol, is confirmed by the data we have obtained in Table 1. These data indicate that isobutanol, which is fractionated from it by isoamyl and amyl alcohol (propyl isobutanol solvent, TS 10-18, USSR 117-88, produced at Kedainiai biochemistry plant) is ineffective at a concentration of 3-10% (isobutanol 1.5-5). , 0% v / v), from commodity benzenesin and ethanol (esters-aldehyde fraction). Propyl-isobutanol solvent composition: 1-propanol 25-30%, isobutanol 50-55%, ethanol 10%, water 10%. Our transparent, stable water-benzine-ethanol fuel composition consists of unethylated petrol, ethanol-based spirit, water additive, and stabilizer-spirit mixture based on isobutanol.

The composition uses unleaded car gasoline A-76 (GOST 2084-77), manufactured by Valst. Mažeikiai Oil Refinery. Spiritual 5

It is a fraction of esters of aldehydes with the following composition: 92% ethanol, 8% other octane oxygen compounds and water. The mixture of high octane oxygen compounds includes dicarbonic acids (1.0g / l), their aldehydes (35g / l) and esters (30g / l), methanol (0.05%) and higher spirits. Table 1

EN 3299 B is a 50% w / w mixture of spirits and 50% water. The spirit mixture consists of: 7% 1 propanol, 24% isobutanol, 19% 3-methyl-1-butanol and 2-methyl-1-butanol (isoamyl alcohols) and n-pentanol (amyl alcohols), i. y. Our stabilizing spirit mixture is based on isobutanol, isoamyl and amyl alcohols with very good stabilizing properties (see EP patent No. 0162122). The ethanol additive and stabilizer of our proposed composition is a waste of rectified ethanol production - cheap, affordable, without the need for a wider application material. Fulse - performs the utilization of which makes an ecological problem. The solution we propose is illustrated by the data below (Table 2.3). Table 2

The data in Table 2 shows that the composition of 5-32% by volume of the ester-aldehyde fraction and 68-95% of the commercial non-methylated unleaded petrol A-76 without the stabilizer is opaque and unstable in the 20s. The data in Table 3 show that 16-19% by volume of the ester-aldehyde fraction, 6-10% by volume of the stabilizer fusion and 74-78% by volume of the commercial non-ethyl benzene composition is transparent and stable. The suitability of the composition examples in Table 3 for a conventional carburettor engine without significant changes in its design is demonstrated by sample bench testing. Engine Type - GAZ-24. Jerkers in carburettor are standard. When working with fuel mixtures, the damper between the pump and exhaust pipes is adjusted to " Winter ", the air filter to the air filter, which covers the heated engine block.

LT 3299 B 10

Selecting the ratio of petrol, esters-aldehyde fraction, and fusion, gives a transparent, stable, water-benzine-ethanol fuel composition suitable for use in a conventional carburetor motor, comprising 14.7-17.5% by volume ethanol, 4.3-6 , 3% v / v water, 3.0-5.0% v / v stabilizer (isobutanol based spirit mixture) and 74.0-78.0% v / v petrol A-76. The 4.3-6.3% by volume water additive reduces the amount of aldehyde contamination in the combustion engine while operating this 10-fuel composition. The use of fusion to stabilize the fuel composition solves the production waste - the fuse utilization problem.
