Abstract
A method for manufacturing biodiesel comprises the steps of: a) getting an amount of biological oil; b) adding catalysts to the oil; and c) getting the biodiesel. The biological oil is from plants. The volume ratio of the catalysts is between 30% to 70% and the other is the oil. The biological oil is replaced by methyl ester. Or the biological oil is animal oil. The catalyst is alkane or alcohol. Time period for manufacturing the biodiesel is short and cost is low without environment pollution. Thereby it is advantageous than the petrifaction fuel.
Description
- The present invention relates to biodiesels, and particularly to a method for manufacturing biodiesel, which is acquired by getting an amount of oil selected from one of planted oil and animal oil; and then adding catalysts to the oil. The time period for manufacturing the biodiesel is short and cost is low without environment pollution. Thereby it is advantageous than the petrifaction fuel.
- In the past, the coals and petrifaction material are main source of fuel. However currently, it is known that these power sources will exhaust in the near future. In some estimation, the reverse of petrifaction material only supports 30 to 40 years for human use and the coal is about 100 years. It is know that the coal and petrifaction materials have serious problems about environmental pollution.
- Currently, the thickness of the carbon dioxide in atmosphere is about 3.75/10000. In 19 century, the data is 2.75/10000. Most of the reason is induced from the use of petrifaction material. If now human stops to use these material, it is estimated that about 1000 years are needed to make the atmosphere return to the value in 19 century. The Kyoto protocol to the United Nation Framework convention on climate change concluded in 2003 requests all the nations to reduce the use of petrifaction material to only 70% of the original usage. Thereby there is an eager demand for a novel invention which can replace the petrifaction material.
- In the manufacture process of the current petrifaction material, a great number of steps are necessary, such as adding catalysts, decomposition, combining, separation, withdrawing grease and water, reuse of methyl alcohol, testing, filtering, etc. The time period is at least 12 hours and a great cost is needed.
- Because above mentioned defects in the petrifaction material, biodiesel now become a popular material for replacing the prior fuel. The biodiesel is also called as fatty acid ester. In that the plant oil from plant fruits, seeds, plant conduits, or some wasted foods are used as original material and then the original material is reacted with catalysts. The biodiesel is poisonless, decompositable biologically, low sulfur, capable of being reused, without aryl, etc. Thereby it partially replaces the petrifaction material.
- The molecule of diesel has about 15 carbon chains, while the biodiesel has about 14 to 18 carbon chains. This number is approximately equal to that of the diesel. The biodiesel is a high fatty acid methane which is acquired by decomposing the glyceride with non-saturated C18. Many plants are suitable to be as the material for manufacturing biodiesel. Thereby the biodiesel can reduce the wear of engine with very little sulfur gas. It is low environmental polluted and suitable for the requirement of environmental protection.
- The advantages of the biodiesel will be described herein.
- The biodiesel contains very low sulfur and thus exhaust of sulfur dioxide and sulfide are lower than the petrifaction about 30%. If catalyst is used, the value is increased to 70%. The biodiesel has no aryl hydrocarbon. The harm of the biodiesel to the human body is lower than the diesel. Comparing with the diesel, the biodiesel can lower the toxicity to be only 10% of the original diesel and harmfulness is reduced to 6% of the original diesel. Comparing with diesel, only 10% of carbon oxide is exhausted (under 95% of catalyst). Furthermore, the engine can be actuated at a lower temperature with a cool filtering point of −20° C. without any additive. Furthermore, it is a preferred lubrication so that the wear to the oil ejection pump, cylinder and linkage is low. Moreover, the biodiesel is a security oil and thus it is preferred in transformation, storage and use. The biodiesel has sufficient sixteenth alkane. It has preferred properties in combustion. The residue after combustion is slight acidic so as to prolong the lifetime of activity and engine oil. Besides the biodiesel can be reused and is not exhausted. Further, the biodiesel is preferred under consideration of cool filtering point, sparkling, combustion, sulfur containing, oxygen containing, oxygen consumption in combustion, harmfulness to water sources as comparing with the petrifaction.
- In 2003, Europe union has requested all the nations to increase the use of biodiesel to 2% at the end of 2005 and to 5.75% at the end of 2010. However there are some problems occurred in the manufacturing of biodiesel, such as high cost and low production due to complication in the manufacturing process. In use, the oil box, oil circuit, and electric devices and engine must be modified. The burning point is not a safe one and sparkle point is not preferred. Great explosion generates vibrations. High sulfur, high deposition and a great amount of water occur.
- Accordingly, the primary object of the present invention is to provide a method for manufacturing biodiesel, which is acquired by getting an amount of oil selected from one of planted oil and animal oil; and then added catalysts to the oil. The time period for manufacturing the biodiesel is short and cost is low without environment pollution. Thereby it is advantageous than the petrifaction fuel.
- A method for manufacturing biodiesel comprises the steps of: a) getting an amount of biological oil; b) adding catalysts to the oil; and c) getting the biodiesel. The biological oil is from plants. The volume ratio of the catalysts is between 30% to 70% and the other is the oil. The biological oil is replaced by methyl ester. Or the biological oil is animal oil. The catalyst is alkane or alcohol.
- In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
- Referring to FIGS. 1 and 2, the process of the present invention comprises the steps of: a) getting an amount of oil which is selected from one of planted oil and animal oil; b) adding catalysts to the oil; and C) getting the biodiesel.
- In the present invention, the volume ratio of the catalysts is between 30% to 70% and the other is the oil. Or the volume ratio of the catalysts is between 30% to 70% and the other is methyl ester. Preferably, the ratio of the catalyst is equal to the oil. The catalyst is preferably alkane or alcohol.
- The advantages of the present invention will be described herein. Firstly, the process can be proceeded quickly and simply. Only several minutes are needed to get the biodiesel, while the conventional petrifaction material needs at least two hours for the reaction. Furthermore, the cost is low. The cost of the present invention is about USD$290/kl, while the conventional petrifaction material needs USD$600˜900/kl. The cost for the equipment in the production according to the present invention is about USD$79liquid 2, while the conventional petrifaction material needs about USD$1000-2500/1. Furthermore, the biodiesel of the present invention can achieve the complete combustion of the fuel in the engine.
