Due to increasing price of fuel in world market, we have nothing to do to stop it. But we can do something alternative, this is called "biodiesel" this renewable fuel which may be used as an alternative to diesel fuel without any modification of the engine. But the question is, is this legal? Certainly yes, except in the country like Saudi and Philippines, because this affect the fuel business in the country so the government cannot fully legalize it at the moment. But this is fully legal if you use it own your own. So lets start!
Materials needed: -isoprophyl alcohol 70-100% solution
-methyl alcohol (methanol)
-lye/lye solution (naOH)
-turmeric solution
-1 liter waste vegetable oil (WVO)
-4 syringe (with labels of oil, lye solution, turmeric, isop. alcohol with 10ml/cc)
-weighing scale ( grams)
-thermometer
-small jar or container
-beaker (250ml or higher)
-blender (take note if you use it in biodiesel do not use it again into food or drink)
Making tester solutions
In making lye solution, prepare 1 liter of distilled water, put 1 gram of lye and dissolve it.(this can be poisonous if they drink so keep out reach of children)
In making of turmeric solution, place 10ml of isoprophyl alcohol in small jar, mix it with 1 tbsp of turmeric and allow it immerse.
So everything is ready, lets do the first part.
First thing to do "titration"
What is titration? In this method you will know the ph balance of WVO you will use and know how many lye(naOH) will be needed.
- Put 10ml of isoprophyl alcohol in a small jar, now get your turmeric solution and syringe with pin and gather few amount of turmeric solution now put it drop by drop in a small jar with alcohol while swirling and it should be turn to yellow.
- Gather few amounts of lye solution put it drop by drop into the jar while swirling it should be turn to red.
- Get your WVO and gather 1ml of oil put it all into the jar and swirl it until it turns to yellow (the oil should be luke warm to change to yellow perfectly)
- Gather 5ml of lye solution, put it drop by drop into the jar while swirling, it should be turn to pink(like pomelo color) dont stop until it change to pink.
- Check your syringe you use in lye solution, count how many point or ml you use in step number 4, the result will be use in nest step.
- Prepare your weighing scale and lye (dry), weigh 5 grams plus titration results and put it into beaker, add 200ml of methanol and mix it until the lye powder dissolve.(don't inhale the fume)
1 liter of oil x 5grams +titration(?)=5.? of lye Amount of Methanol=200ml
Large batch
80 liters of oil X 5grams + titration=400.? of lye AOM=enough to dissolve the lye
7.Prepare your blender and 1 liter of oil, heat the oil, use your thermometer to measure it up to 45°C
8.Place it into the blender, mix it with your lye and methanol mixture. Blend it up to 30mins. After that pour it into empty jar or bottle. Wait up to 24hrs.(this will allow the biodiesel (top) and glycerol (below) to separate)
9.Separate the biodiesel (light color) in another bottle or container with cap, keep the glycerol for other purpose, and there you have it!
But wait! Do you want to improve the color and quality of your biodiesel? Then you need to wash it, washing is simple. Just add 100ml of water and shake it. (shake it gently, give it 2 shakes side by side). Allow the biodiesel and water to separate, (remember that water is heavier than oil) so the water will go down, then drain the water. Do this repeatedly until the water is clear. Mostly 3 times washing will work best. Next is drying, this will allow to dry the water particles in biodiesel that cannot be separate by draining. Leave it to the sun within 2-3days. You will notice the clear color of your biodiesel. If you are in hurry, just heat it in the pot up to 60°c to dry water particles in it.
That's it, you've make biodiesel!
Congratulations! You have now successfully completed your first biodiesel fuel ever. Boost your engine with this extraordinary fuel and feel the difference!
