Description
METHOD FOR MANUFACTURING BIODIESEL FUEL FROM
VEGETABLE OIL
Technical Field
[1] The present invention relates to environmentally friendly internal combustion engine biodiesel fuel by using vegetable oil, and a method of manufacturing the same. Background Art
[2] As the manufacture of industrial machines and vehicles including diesel engines has rapidly increased worldwide with the development of industry, the consumption of diesel oil used as an energy source has been increased. As compared to various fuels obtained from crude oil, diesel oil is inexpensive, and thus is advantageous in the view of cost reduction, but has a problem of generating a large amount of air pollution after its combustion.
[3] In order to solve such a problem, research on alternative fuel having physical properties similar to diesel oil and being capable of preventing air pollution has been variously conducted. As a result of the research, research on biodiesel oil having physical properties similar to diesel oil and being capable of significantly reducing the occurrence of air pollution is being actively conducted.
[4] Biodiesel is fatty acid ester obtained from vegetable oil or waste oil, which is manufactured by a reaction for generating a low molecular alcohol through the action of an acidic or basic catalyst. Also, since the biodiesel has physical properties similar to light oil (energy source of a diesel engine), the biodiesel may be used in combination with the light oil or may be used in a diesel engine as a substitute for the light oil.
[5] In the present invention, an acidic or basic catalyst is used to carry out an ester- ification reaction, and centrifugal separation is carried out to separate glycerin (glycerol) from the reacted product, and to filter out additionally generated non- esterified materials, such as alkalies (hydroxyl group). Thus, it is possible to increase the yield of the manufacturing process, and to solve all problems with the fuel.
[6] In this manner, a method of manufacturing environmentally friendly biodiesel by using residual products (such as, alkalies (hydroxyl group)) and ethanol acids (glycolic acid) was completed. Disclosure of Invention
Technical Problem
[7] Therefore, the present invention has been made in view of the above-mentioned problems. The present invention provides environmentally friendly internal combustion engine biodiesel fuel by using vegetable oil, which can reduce envi-
ronmental pollution, and a method of manufacturing the same. Technical Solution
[8] The above mentioned biodiesel is fatty acid ester obtained from vegetable oil or waste oil, which is manufactured by a reaction for generating a low molecular alcohol through the action of an acidic or basic catalyst. [9] Preferably, raw materials for the biodiesel may require pretreatment because the manufacture of the biodiesel requires the esterification of waste oil and the use of moisture, which may affect an esterification reaction. [10] Preferably, pure vegetable oil is a raw material, not concerned with the purity, moisture, and acid value (rancidity) in the manufacture, and thus may be fed through direct esterification. [11] Preferably, as a catalyst, an acidic or basic additive, such as KOH, K CO , NaOH, and NaOCH , may be used. In particular, it is the most preferable to use a basic catalyst. [12] Preferably, a low molecular weight alcohol includes methanol and ethanol, and the raw materials generate recycling energy through a manufacturing process by using residual products of refined fermentation/fossil fuel.
Advantageous Effects
[13] According to the present invention, it is possible to reduce the import rate of fossil fuel on which the rate of import dependence is the highest at the present time, to decrease the amount of exhaust gas from air pollution materials to a minimum, and to improve process efficiency of biodiesel (alternative fuel of recycle energy) through the best yield, and a separation refining process. Also, since vegetable oil, a recycle energy source, is used, its residual products may be re-used. Mode for the Invention
[14] Hereinafter, reference will now be made in detail to the preferred embodiments of the present invention. However, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
[15] Example
[16] Example 1: Manufacture of biodiesel fuel
[17] The fuel according to the present invention was manufactured through esterification of materials noted in Table 1 by a catalyst (KOH or NaOH). The materials were reacted at a driving pressure of 3 to 4 atm, at 70 to 8O0C and were separated into layers by the specific gravity difference in a settling tank. Then, a separated glycerin (glycerol) layer was removed. A centrifugation process was carried out to filter out residual non-esterified materials, such as alkalies (hydroxyl group), and a purification
process was performed.
[18] In manufacturing the fuel, a vacuum evaporator was used to carry out the reaction at 6O0C for 3 hours in a batch reactor. [19] Table 1 [Table 1] [Table ]
[20] In Table 1, the other additives include a flash point increasing agent, 16 octane booster, an ash preventing agent, and an anti-freezing agent.
[21] Example 2: Composition test [22] Table 2 shows the composition test results of the fuel obtained from Example 1. [23] Table 2 [Table 2] [Table ]
[24] Example 3: Test on exhaust gas [25] Exhaust gas from a Korean vehicle in which the fuel obtained from Example 1 was injected was analyzed (see Table. 3).
