Simple Way To Make Bio-Diesel in 5 Easy Steps

Howdy All,

Below is a posting from on how easy it is to make bio-diesel. If you are interested in learning to make your own fuel, here's your simple formula in 5 easy steps...jpf:
Biodiesel is a relatively clean fuel that can work as effectively as other fuel sources in powering machines. In fact, biodiesel was one of the first energy sources for vehicles every conceived and was used widely during World War I to provide a reliable power source for military vehicles that often went on long missions to remote areas of the world where there was not always easy access to fuel.

Biodiesel fuel service stations are popping up in areas across the country. But you don’t need to buy your biodiesel fuel from a service station; if you have machine that takes biodiesel fuel, such as a vehicle or lawn mower, why not make your own biodiesel? Here’s how:

Materials you’ll need:

* Petri dish
* 10 ml beaker
* 1500 ml beaker
* 50 ml beaker
* Isopropyl alcohol
* Graduated eye dropper
* Litmus paper
* Blender
* Glass bowl
* Methanol
* Used cooking oil
* Sodium hydroxide
* Distilled water

Step 1: Titration

You need to titrate to determine how much of your catalyst you need for a reaction. Here’s how to titrate:

1. Put 1 Lt of distilled water into the 1500 beaker.
2. Put 1 gram of sodium hydroxide into the beaker with the water.
3. Put 10 ml of isopropyl alcohol into the 20 ml beaker.
4. Add 1 ml of used vegetable oil to the alcohol beaker.
5. Label the mixtures separately.
6. With the eye dropped, add 1 ml of sodium hydroxide solution to the alcohol solution.
7. Check the pH of the alcohol solution.
8. Continue to add the sodium hydroxide solution to the alcohol solution until the combined solution reaches a pH level between 8 and 9.
9. Use this equation for the rest of the recipe:


X = Number of ml of sodium hydroxide solution dropped into alcohol solution

N = Number of grams of sodium hydroxide solution necessary to neutralize and change 1 l of vegetable oil. This number will be between 4.5 and 6.5.

Step 2: Measure and separate your reactants

Now you will measure your reactants in separate containers.

1. Place 1 l of used oil into the 1500 ml beaker.
2. Place 200 ml of methanol into the 500 ml beaker.
3. Place N grams of sodium hydroxide onto the petri dish.

Step 3: Combine sodium hydroxide with the methanol to create sodium methoxide.

Now it’s time to combine the methanol and sodium hydroxide. This combination will create sodium methoxide, which is a very strong base.

1. Pour the methanol into the blender.
2. Pour sodium the hydroxide into the blender.
3. Blend the mixture for 30 seconds. The sodium hydroxide should dissolve.

Step 4: Combine the reactants.

Now it’s time to add the reactant: oil.

1. Using causing, pour the vegetable oil into the blender with the sodium methoxide.
2. Blend for 15 seconds on a medium or high setting.

Step 5: Let glycerine settle.

You’ll need to wait about 8 hours for the glycerine to settle to the bottom. 75% of the separation in the mixture will occur within the first hour after adding the reactants. Once the glycerine settles to the bottom, the remaining top layer is methyl esters–biodiesel.

You can use the glycerine as soap and the biodiesel to fuel your biodiesel motor! Now that’s an easy-to-make–and affordable–fuel source!

To cleaner, more affordable power,
