Description

Modified version composite lead-free gasoline and compound method thereof

Technical field

The present invention relates to a kind of fuel and compound method thereof, relate in particular to a kind of composite lead-free gasoline and compound method thereof.

Background technology

Existing composite lead-free gasoline generally is made up of methyl alcohol, dimethylbenzene, industrial naptha, and there is following shortcoming in this kind composite lead-free gasoline: when (1) surpassed 45 ℃ at temperature, methanol activity strengthened, and easily forms vapour stream, thereby air-resistance phenomenon takes place; Otherwise when temperature was extremely low, this composite lead-free gasoline convergency increased, and oil circuit then takes place freely do not cause being difficult for starting.(2) adopt industrial naptha to make main raw material, because the various unstable properties of industrial naptha, so the octane value fluctuation is bigger, and phenomenon of detonation takes place sometimes.(3) owing to the general higher stability that influences composite gasoline of industrial naptha gum level.(4) have certain corrodibility, can produce certain influence oil circuit.(5) when mixing use with conventional gasoline, be prone to demixing phenomenon.

Summary of the invention

The objective of the invention is at above-mentioned shortcoming, provide a kind of and have good vapo(u)rability, anti-knocking property and stability, erosion resistance is good, can mix the modified version composite lead-free gasoline of use with traditional gasoline product, ethanol petrol arbitrarily.

For this reason, modified version composite lead-free gasoline of the present invention is characterized in that: be made up of following weight percentages:

Methyl alcohol 30%-60%

90# gasoline 15%-35%

Propyl carbinol 1%-15%

Virahol 1%-15%

Modification alcohol (also claiming dehydrated alcohol) 3%-30%

Dimethylbenzene 1%-10%

Acetone 0.1%-10% reaches

Core additive 0.0008%-0.0015%, this core additive is made up of zinc oxide, oxidation inhibitor, metal passivator, tinting material and smoke abatement combustion adjuvant.

Modified version composite lead-free gasoline of the present invention, preferably form by following weight percentages:

Methyl alcohol 40%-60%

90# gasoline 15%-25%

Propyl carbinol 5%-10%

Virahol 3%-15%

Modification alcohol 3%-5%

Dimethylbenzene 1.999%-5%

Acetone 4.999%-10% reaches

Core additive 0.0010%-0.0015%.

The effect of core additive is divided into effect and the effect of composite lead-free gasoline in the automobile use in building-up process; its function is simply the adding up of simple function of several constitutive materials anything but; in the building-up process of composite lead-free gasoline; the core additive rises and shortens the chemosynthesis time; coordinate various industrial chemicals molecule contacts; change intermolecular reactive force; make the synthetic particulate increased activity that is polymerized, reach the abundant and maximized purpose of chemical energy of atomizing when in engine, using.When composite lead-free gasoline burns use in motor car engine, the core additive has converging action to distributing of heat energy under specific High Temperature High Pressure, thereby guaranteeing does not have unnecessary heat energy dissipation, and the utilization ratio that makes heat energy be converted into mechanical energy improves, and reaches the purpose of Conversion of energy optimum.In the composition of core additive, various compositions do not have strict material and proportion requirement, and only need possess functional requirements such as antioxygen, passivation and smoke-eliminating combustion-aid can reach technical purpose.

The weight ratio of described zinc oxide, oxidation inhibitor, metal passivator, tinting material and smoke abatement combustion adjuvant can be 1: 1: 3: 5: 8, more excellent in the core additive over-all properties of this ratio preparation.

Another object of the present invention is to provide a kind of method of preparing above-mentioned modified version composite lead-free gasoline, it is characterized in that may further comprise the steps:

(1) blends the Generation Liquid body additives in proportion with core additive and acetone;

(2) blend in proportion with propyl carbinol, Virahol, modification alcohol and dimethylbenzene, generate mixture A;

(3) blend with methyl alcohol and mixture A, generate new mixture B;

(4) blend with fluid additive and 90# gasoline, generate maternal gasoline;

(5) blend with maternal gasoline and new mixture B, obtain the modified version composite lead-free gasoline.

The present invention compared with prior art has the following advantages:

1. vapo(u)rability is good, and guarantee that engine easily starts in the winter time, and also be difficult for producing vapour lock in summer, and can sufficient combustion.

2. anti-knocking property are good, owing to use 90# gasoline, its octane value conforms with the regulations, and it is little to fluctuate, and has guaranteed that running of an engine is normal, pinking can not take place, and gives full play to power.

3. owing to use 90# gasoline to make main raw material, its existent gum≤5, so its stability is better.

4. erosion resistance is good.

5. added modification alcohol owing to the modified version composite gasoline, and made this modified version composite gasoline to mix use arbitrarily, demixing phenomenon can not occur with conventional gasoline and ethanol petrol.
