Abstract

PURPOSE: Provided is an alcohol fuel for substituting gasoline or an additive of gasoline, which is low pollution fuel and has high octane value and can be used in a conventional gasoline internal combustion engine car without changing structure of the car. CONSTITUTION: The alcohol fuel comprises 54wt.% of alcohol, 12wt.% of isopentane, 10wt.% of C9+, 10wt.% of hydrotreated light naphtha, and 14wt.% of xylene, wherein the alcohol comprises 38wt.% of methanol, 8wt.% of isobutanol, 4wt.% of isopropyl alcohol, and 4wt.% of M.T.B.E. The alcohol fuel exhausts lower amount of HC, NO, and NOx than conventional gasoline.

Description

Gasoline Additives and Fuels (Gasoline Alternative Fuels) {An addition of Gasoline & Fuel.}

Fuel that can be used as it is without modification to the existing gasoline internal combustion engine cars can be used in any case of gasoline, gasoline + alcohol fuel, alcohol fuel, and high octane number. Hazardous Gas Components Caused by Pollution The emission of HC, NO, NOx, and other emissions is lower than that of gasoline.

[001] When the alcohol fuel is used in a gasoline internal combustion engine car, there is a problem that the air mixing ratio is adjusted by adjusting the inlet manifold of the inlet manifold because the air mixing ratio does not match.

[002] Due to the corrosion of methanol, there was a problem in that the materials of fuel tanks, pipes, and rubbers had to be improved.

Since methanol has a high heat of vaporization, there is a problem in startability, and since distillation temperature is constant, there is also a problem in running and acceleration.

If you solve the above problem is not compatible with the gasoline internal combustion engine cars there is a difficulty in the actual use.

The development of an internal combustion engine compatible with gasoline has not yet been made, the internal combustion engine compatible with gasoline has a problem that the price is expensive because additional equipment is required.

[006] The problem of adjusting the inlet man-ifold of the inlet port by making the air mixture ratio of alcohol fuel equal to gasoline

[007] Problem of making corrosiveness equivalent to or better than gasoline so as not to improve the material of fuel tank, pipe, rubbers due to corrosiveness

[008] Good startability, running, acceleration is also excellent, fuel economy is equal to or better than gasoline.

[009] To make a compatible fuel that can be used in existing gasoline internal combustion engine cars without any structural improvements.

[010] It is high octane number and makes fuel of low pollution.

The basic idea of the invention is to make a low pollution fuel excellent in the global environment, and to make a fuel that can be used as it is in a conventional gasoline internal combustion engine car. The alcohol fuel of the invention was selected raw materials to make the technical problems that the invention is to achieve, startability problems, corrosive problems, compatibility problems, high octane number, low pollution fuel.

The fuel composition of the present invention was methanol, isobutanol, isofurophyll alcohol, MTBE, alcohol, and isopentane, C9 ⁺ Hydrotreated Light Naphtha, xylene was used to solve the problem, methanol Alcohols of four kinds of isobutanol, isofurofill alcohol, and MTBE are 6 to 8 in weight ratio of methanol, 1.2 to 1.6 in weight ratio B of isobutanol, and 0.5 to 0.5 in isopropanol alcohol with respect to the total amount of alcohol fuel. 1, MTBE weight ratio D is 0.8-1.4, and the alcohol component was set to 54 +/- 5 wt% with respect to the total amount of alcohol fuel.

If the total amount of alcohol to alcohol fuel is more than 52 + 5wt%, there is a problem that can not be used in all internal combustion engine cars due to the difference in displacement, less than 52-5wt% is classified as a distillate such as gasoline, alcohol It will not be approved as fuel.

[014] The weight ratio A: B: C: D of methanol A, isobutanol B, isofuropil alcohol C, MTBE D with respect to the total amount of alcohol to alcohol fuel is (6-8) :( 1.2-1.6) :( 0.5 ~ 1) :( 0.8 ~ 1.4) to make the total alcohol 54 ± 5wt%, isopentane 10 ± 5wt%, C9 ⁺ 10 ± 5wt%, light naphtha 10 ± 5wt%, xylene 15 ± 5wt% Configured.

Harmful components HC, NO, NOx, etc. of exhaust gases that cause high octane number and low-pollution fuel pollution can make alcohol fuel which is significantly reduced compared to gasoline. The problem of material change of fuel tanks, pipes and rubbers due to corrosiveness has been solved. The alcoholic fuel of the invention can be used in the existing gasoline internal combustion engine cars without any structural changes and improvements. In the case of gasoline automobiles, we have invented fuels that can be used in any case, such as alcohol fuel, gasoline, gasoline + alcohol fuel, but due to the problem of recognition and trust, we have applied for the invention as gasoline additive and gasoline alternative fuel.
