Description

Vehicle light hydrocarbon fuel composition

Technical field

The present invention relates to a fuel for vehicles, and more particularly to a light hydrocarbon fuel composition for vehicles. Background technique

Methanol oxygen molecular content of 50% (gasoline oxygen molecular content of 0), burning rate of 52 m / s (M / S) (gasoline 38M / S), methanol combustion heat value is only half of gasoline, methanol and hydrocarbons (hydrocarbons) After the fuel is mixed, it is burned in the cylinder. Since the combustion rate is fast, the average effective pressure of the engine cylinder is higher than that of using gasoline, so the same amount is used, and the vehicle runs the same distance as the gasoline.

Methanol is a product of coal and natural gas production. 1.5 to 1.8 tons of coal can produce 1 ton of methanol. The cost is much lower than that of gasoline. The price is only about 40% of No. 90 gasoline. Light hydrocarbons (butane, pentane, and hexane mixed hydrocarbons) are by-products of petrochemical refineries. Because of their low Xinji value and extremely high volatilization, they cannot be used directly as motor gasoline. How to combine methanol with petrochemical refinery by-product light hydrocarbons to make them useful as fuel for vehicles is a topic of great concern. Summary of the invention

The technical problem to be solved by the present invention is to disclose a light hydrocarbon fuel composition for vehicles to overcome the drawbacks of the prior art. Meet the needs of the development of related fields.

The technical idea of the present invention is as follows:

The invention contemplates a mixture of anhydrous methanol or anhydrous ethanol, light hydrocarbons (butane, pentamidine, hexane mixed hydrocarbons) and toluene or xylene or toluene-producing oils and light aromatic hydrocarbons plus fluorocarbon surfactants. It replaces the automobile gasoline fuel to improve the combustion heat value and anti-explosion performance of the fuel. The cost is low, and the fuel can be saved. At the same time, the emission of exhaust pollutants can be reduced, which is very helpful during the period of tight oil resources.

The light hydrocarbon fuel composition for vehicle of the present invention, the parts by weight of the components are as follows:

Light hydrocarbon 100 parts by weight

Anhydrous methanol or absolute ethanol 1-100 parts by weight

Cosolvent 0-52 parts by weight Aromatic hydrocarbons (toluene, xylene or toluene oil and light aromatics)

3-100 parts by weight

Cationic fluorocarbon surfactant . 0.004-0.04 parts by weight

CMT (cyclopentadienyl manganese tricarbonyl) 0-0.66 parts by weight of light alkanes is a mixed hydrocarbon of butyl hydrazine, pentane and hexane, which is a by-product oil of petrochemical refinery, light solvent Oil, C5 component and other products, such as pentane fraction separated by natural gas condensate;

The co-solvent is selected from the group consisting of methyl tert-butyl ether (MTBE), methyl tertamyl methyl ether (TAME), tert-butyl alcoho (TTA) or One of isobutanol or the like;

MTBE, TAME, TBA are excellent gasoline antiknock agents, and isobutanol is a cosolvent that also improves the evaporation performance of gasoline. Toluene and xylene are both cosolvents and octane number and combustion calorific value improvers.

The anhydrous methanol must use anhydrous methanol with a weight purity of 99.5 % or more. The product is derived from coal or natural gas and is treated with water removal. The anhydrous methanol is one of the future energy sources expected by mankind. Anhydrous methanol, anhydrous ethanol, MTBE, TAME, TBA, isobutanol, etc. are all oxygen-containing compounds, which can make the combustion of the alcohol-hydrocarbon fuel composition more complete and contribute to the improvement of environmental pollution.

Anhydrous methanol or absolute ethanol is added in an amount of from 1 to 100 parts by weight based on 100 parts by weight of light hydrocarbons (butane, pentylene, and mixed hydrocarbons), depending on the octane of the light hydrocarbon used. Value (RON) depends. For example, the octane number (RON) of light hydrocarbon is 82, the octane number (RON) of anhydrous methanol is 110; 15 parts by weight of anhydrous methanol is added with 15 parts by weight of aromatic hydrocarbons and light hydrocarbons (butane, pentane, ruthenium) Mixture) 70 parts by weight, the octane number (RON) of the methanol light hydrocarbon fuel is 90, which is generally suitable for use in automobiles with an engine compression ratio of 9.0:1 or less, instead of No. 90 gasoline.

Further, 20 parts by weight of anhydrous methanol, 70 parts by weight of light hydrocarbons mixed, 10 parts by weight of mixed aromatic hydrocarbons, 0.0025 parts by weight of CMT, and an octane number of 93 units, which is suitable for use in automobiles having an engine compression ratio of 9.3:1 or less, instead of 93 No. Gasoline. 25 parts by weight of anhydrous methanol, 5 parts by weight of auxiliary solvent MTBE, 60 parts by weight of mixed light hydrocarbons, 10 parts by weight of aromatic hydrocarbons, 0.0025 parts by weight of CMT, and an octane number of 95 units, suitable for engine compression ratio of 9.5:1 for automobiles , replacing the 95th gasoline. Anhydrous methanol is divided into 30 parts by weight, 25 parts by weight of aromatic hydrocarbons is added, and 45 parts by weight of light hydrocarbons are mixed, and the octane number thereof is more than 97. It is suitable for engine compression ratio of 9.5:1 to 10:1 engine, instead of standard gasoline No. 97. Since anhydrous methanol or anhydrous ethanol and light hydrocarbons (butane, pentane, hexane mixed hydrocarbons) are mutually soluble at room temperature, they are easily stratified after mutual dissolution, especially when the steam temperature is lower than 15 °C. Poor, for this shortcoming, fluorocarbon surfactants, which are both hydrophilic and lipophilic, highly diffusible, and uniformly attached to the interface of methanol with hydrocarbons (light hydrocarbons, aromatics) And form a thin film on the metal and rubber surface, which has strong anti-corrosion, anti-rust and anti-wear effects; if necessary, use a solvent to solve this problem. When anhydrous methanol or anhydrous ethanol and light hydrocarbons have a good mutual solubility at temperatures above 15 °C, it is necessary to reduce the amount of co-solvent. The cosolvent may be used in an amount of from 0 to 52 parts by weight based on 100 parts by weight of the light hydrocarbon (butane, pentamidine or hexane mixed hydrocarbon), and it is not necessary to add a co-solvent at a high temperature to achieve the object. • Aromatic hydrocarbons include toluene or xylene or mixtures thereof, toluene oils, light aromatics, and the like. The fluorocarbon surfactant is a fluorodecylamine salt or a quaternary ammonium salt cationic fluorocarbon surfactant selected from one of the formulas (1), (2) or (3) or a mixture thereof:

(1) Fluorinated alkylamine quaternary ammonium salt type cationic fluorocarbon surfactant:

(3) fluoroalkylamine salt type cationic fluorocarbon surfactant:

[F(CF ₂ ) ₈ CH(OH)CH ₂ ] ₂ NCH ₂ CH ₂ NH ₂ 'H ₂ S0 ₄ .

The fluorocarbon surfactant is added in an amount of 0.004 to 0.04 part by weight, preferably 0.006 part by weight, based on 100 parts by weight of the light hydrocarbon (butane, pentane or hexane mixed hydrocarbon). In the present invention, (1) a fluorine-containing alkylamine quaternary ammonium salt type cationic fluorocarbon surfactant, (2) a perfluorodecylamide quaternary ammonium type cationic fluorocarbon surfactant, and (3) a fluoroalkylamine salt The type of cationic fluorocarbon surface agent may be used alternatively or in combination.

'MARAVILLA, a fluorocarbon surfactant in Shanghai, can be used in the present invention. It is produced by Shanghai Wenjing Fine Chemical Co., Ltd., 100 parts by weight of butyl hydrazine, pentane and hexane. The hydrocarbon, MARAVILLA, is added in an amount of 0.004 to 0.04 parts by weight, preferably 0.006 parts by weight.
