About the biodiesel plant
The wasted oil of the "Tempura" is made the fuel of an environment friendly diesel engine.
（Recycling of oil used when tempura is fried ）
The environment-friendly biodiesel fuel that does not exhaust the carbon dioxide that becomes the element of global warming is used for the cropper and the tractor used in Eco-park RONSHOBARU.
It is useful to combat global warming.
1.Garbage truck of Minamishimabara City and caravan of materials transportation.
2.The delivery track at the Kitaarima-cho school lunch center etc. have been operating with 100 percent BDF fuel since November, 2007.
The wasted oil of the "Tempura" is made the fuel of an environment friendly diesel engine.
Wasted oil of for food from the ordinary family is collected in the Eco-park RONSHOBARU. I wish cooperation.
To the person who lives in Minamishimabara City.
Please put the wasted oil of the "Tempura" that finished being used at each home in the special collection container of an integrated branch office in each town. Moreover, it can visit facility of Eco-park RONSHOBARU, and come by all means, please.
The fuel refined in Eco-park RONSHOBARU is recycled by the collection car of the burnable waste that goes out of the home(everybody in
Minamishimabara City), and contributes to the loss in weight of the heat-trapping gas of global warming.
The tempura oil is recycled and used for in fuel of a car.
Plant fuel (BDF) does not become a global warming effect gas unlike the fossil fuel.
The reason・・
The carbon dioxide of the plant that repeats the circulation of the respiratory effect that exhausts water though the carbonic acid anabolism of the plant is an action of carbon dioxide and oxygen put out It does not become a global warming effect gas.
This is called "Carbon neutral". It is a fossil fuel, a substituted thing, and effective renewable energy for measures for controlling global
warming.
BDF is abbreviation of biotechnology, the diesel, and the fuel and the vegetable diesel fuels.
The fuel of gasoline and the light oil used in general now is born the earth and called 3 billion years and 4.6 billion years.
The human race tries to exhaust coal and the oil of limited in underground that multiplies years of the process until present and was
accumulated in hundreds of years.
The human race cannot produce oil but it is possible to make plant in human race's hand and to make the energy.
I think that I should concurrently think about energy problems and environmental problems.
Non-polluting energy still has the possibility in the unknown territory.
There are a solar heat, sunlight, a force of the wind, water power, and seawater, etc.
I think that I have come at the time made from not underground resources but human races' hands.
It is tempura oil that cannot help using a large amount by the idea as one method in life and being abandoned again.
From foreign country to dissatisfaction and valuable resource of import of 85 percent or more in production in Japan though it is regrettable
Recycling this and having changed it into the diesel fuel are BDF. It is an important thing including the environment of the earth.
(it is usually used in Europe)
Refinement of biodiesel fuel
The method of making used oil in the diesel fuel is an alkali catalyst method wet type who has gone to some the one that is in the Eco-park RONSHOBARU now, and a method to wash the one that esters were exchanged by water.
Reactive separation process
It stirs it for 60 minutes while heating it to 60 degrees mixing the catalyst liquid of alcohol and potassium with used oil, spend for 24
hours mixing it with used oil the catalyst liquid of alcohol and potassium.
And separate a glycerin and a methylic ester (becoming it oils and fats element to the origin of the fuel) in natural precipitation the
specific gravity difference.
Process of washing in clear water
A methylic ester is washed by the water of 20% in the tank and it stirs it for about 60 minutes by 60 degrees afterwards.
The catalyst in a methylic ester mixes with water at this time and it becomes a milk color.
After potassium is separated in this process, it is naturally precipitated.
Potassium is removed by repeating a methylic ester repeating this process of washing in clear water until the water collected under the tank becomes transparent.
Dry process
Because water remains in a methylic ester, it heats by 60-70 degrees, and it decompresses it.
The biodiesel fuel can be done by the thing evaporated for two hours - about three hours until moisture is completely lost.
The waste fluid that comes out with the by-product is used as washing the machine and a fertilizer of the farm in Eco-park RONSHOBARU, too.
About the quality of the BDF fuel
The fuel that is called a biodiesel is an oil constituent called a botanical fatty acid methylic ester. There are some methods of making the biodiesel fuel.
1.Alkali catalyst (sodium hydroxide, caustic soda, and potassium hydroxide, etc.)
2.Acid catalyst (sulfuric acid and fluorine, etc.)
3.Solid catalyst (metallic oxide, zeolite, and ion exchange resin etc. such as calcium oxides)
4.Living thing catalyst (lipase steatolysis enzyme and yeast bacterium body, etc.)
The alkali catalyst method with potassium is done in Eco-park RONSHOBARU.
They are made to react to this by the methanol in the one that is called a triglyceride that unites the glycerin with the fatty acid of three
values, and the vegetable oil exchanges esters and separates the glycerin. A fatty acid methylic ester is obtained especially depending.
The molecular weight of the major ingredient decreases to 1/3 of the oils and fats by this processing, the viscosity is lowered even to the
tenth of oils and fats, and it makes it easily to use as a diesel fuel.
Moreover, can it convert to a methylic ester by mixing alcohol and ignitability (cetane number) necessary for the compression ignition oil
engine be improved at the light oil level.
Botanical carbon dioxide that is the theme of the global warming now circulates through the plant though "Resin" of most plants and
animalities can be used for the raw material of the biodiesel fuel.
It does and because the thing is a problem, the wasted oil of a botanical tempura is suitable for the raw material in the factor of Global
warming.
In general, the kind of a botanical cooking oil used and the content of oil are 40% in the rapeseed, the soybean is 20%, the palm is 40-50%, the helianthus is 30-40%, and 40-50% is included as for corn.
The price is high though methyl alcohol "Methanol" ethanol made from the natural gas in general can be used for alcohol.
It can be said that the biodiesel that uses this because it obtains it by fermenting the sugar such as sugarcane is a true carbon neutral in
the ethanol. The technology that synthesizes the methanol from biogas is developed.
The meaning of "Carbon neutral" rises as well as the ethanol if the methanol that does not depend on the natural gas spreads at a low price. Moreover, the research that moves the gasoline engine mixing the ethanol with gasoline is done, too.
It is a life of the fermentation process though this ethanol is advanced by the manufacturing kind method of the beet sugarcane of using
points that make the shochu in extent to which the influence does not go out of a remaining thing to produce food.
The problem of the production cost is said.
The biofuel becomes a problem in the future like this.
Difference of engine (difference between gasoline engine and diesel engine)
About the engine
The diesel engine is a thermomotor from which it is invented by the engineer Rudolph diesel doctor in Germany, and the patent was acquired in 1893.
He demonstrated the diesel engine that used the peanut oil in the Paris Expo in 1900.
Though he had thought this engine is moved with various vegetable oils at that time.
It is a main current of today because Mercedes-Benz starts in 1936 in the world, the diesel passenger car is developed, and it became a diesel fuel that can make oil at a low price and efficiently at time when oil became popular as a fuel.
1.The gasoline engine generates air and gasoline, and it ignites by the electric spark by compressing the gas in a mixture that can explode and the kinetic energy is generated by the rapid expansion "Rapid combustion".
2.The diesel engine ignites naturally because of the compression heat when the fuel is jetted like the fog while compressing air into the high pressure and having generated heat and generates the kinetic energy by rapid expansion "Rapid combustion".
3.The diesel engine
Because the compression ratio is high, it is necessary to make it strongly compared with the gasoline engine of the same engine displacement though the structures are simpler than the gasoline engines.
The combustor efficiencies are higher than the gasoline engines.
The amount of carbon dioxide of the exhaust is less than that of the gasoline engine.
The exhaust of carbon dioxide that causes global warming decreases if BDF is used for the diesel engine.
