Description
Technical field
The present invention relates to be used for the fuel composition of oil engine, relate more specifically to be used for the fuel composition of the alternative fuel of oil engine, it not only can be used for the petrol engine that uses gasoline to act as a fuel, also can be used for the diesel motor that uses light oil to act as a fuel.
Background technology
Because the problem of the petroleum resources exhaustion that the seventies in 20th century " oil shock " causes, and the environmental pollution of the fossil oil problem that become international, say the world today be in the energy and environment struggle in the middle of also not excessive.In order to tackle the internal medium regulation of strengthening day by day (Kyoto Protocol), particularly do not have the country (as Korea S) of petroleum resources should pay close attention to the development of alternative fuel, and should accelerate the development of alternative fuel.
Yet gasoline is widely used as the fuel of oil engine, produces oxycarbide (CO during owing to gasoline combustion
X), oxynitride (NO
X) and oxysulfide (SO
X), these gases enter in the air, so gasoline becomes the air-polluting major cause.
For overcoming the problems referred to above, biological substitution fuel has been subjected to people's attention.The candidate material of fuel as an alternative, can be from the methyl alcohol of preparations such as Sweet natural gas, coal, timber because octane value height (being about 101.5), be applicable to the engine of high compression ratio.When it was used for diesel motor, it can not produce coal smoke when burning, and does not have sulphur, therefore helped significantly to reduce the oxynitride (NO of generation
X) and oxysulfide (SO
X).But, when bio-ethanol (bioethanol) or 100% methyl alcohol are used for existing petrol engine separately, its unit volume thermal value only is about half of thermal value of gasoline, therefore under the identical situation of operating range, needs the fuel tank capacity of twice.And it can corrode petrol engine.Therefore, as long as the structure of existing oil engine does not change, just be difficult to use described bio-ethanol or methyl alcohol.
Research according to U.S. West Virginia Univ., analytical results as methyl alcohol, bio-ethanol and the biofuel of the candidate substances of oil engine alternative fuel is shown, methyl alcohol gives off minimum oxynitride, has therefore obtained the highest scoring aspect preventing the pollution of the environment.The secondth, secondly bio-ethanol is biofuel.
Although methyl alcohol has the advantage that solves environmental problem, when it is used as the fuel of oil engine, show above-mentioned shortcoming.Therefore, people are to ethanol, and particularly the interest of bio-ethanol improves.In fact, in industrial application, usually use synthesizing alcohol, and the Aalcohols fuel bio-ethanol that extracts is similar to methyl alcohol from plant, and bio-ethanol also has the toxicity and the waste gas of reduction.
The advantage that contains the fuel oil of IC engine (composition for example of the present invention) of bio-ethanol is, can add described oil fuel under the situation that does not change existing car combustion engine.At present, use in states such as the U.S., Brazil and be called the gasoline of " ethanol petrol (gasohol) " and the mixture of bio-ethanol acts as a fuel.Therefore but its ignition quality is poor, is difficult in the winter time use, and in the area that the plant resources amount can not fully guarantee, and is limited from the use of the bio-ethanol of plant extract.
Bio-ethanol is to be converted into sugar by the carbohydrate that will contain in the biology, and sugar-fermenting is obtained.When using sugarcane or beet, obtain bio-ethanol by directly therefrom extracting sugar and making the sugar that extracts carry out the alcohol fermentation as sugared source.In addition, biofuel be can make, in the presence of catalyzer, will ethyl ester or methyl esters be formed from the organic oil that extracts of plant (Semen Brassicae campestris, sunflower seed, soybean etc.) and alcohol combination of self-sow by following process.
Aspect ecological friendly, biofuel shows the sufficient possibility of fuel as an alternative, and in developed country's (comprising Europe) practical application.But it can't be used as complete fuel product, but as the additive of diesel oil fuel or in automobile, use with the light oil composition mixture.Therefore, diesel motor is still very high to the fuel dependency of light oil in the prior art.
