Biodiesel Recipe

Let the biodiesel recipes begin...

The World Famous Dr Pepper Technique (Pat Pend)

This is the easiest most fool proof recipe for making your first homebrewed few mini-batches of biodiesel. As an added bonus, the only "specialized" equipment required is a thermometer, accurate scales to measure out NaOH (in a pinch a metric teaspoon measure will work), and something to measure out 250 ml of methanol and 1 litre of vegetable oil.

 CAUTION

If you are new to Biodiesel making, a few words of caution are in order: Read the safety tips here

Equipment

  • * 1-2 liter (1.9 in USA) dry Dr Pepper bottles, with top, both in sound, airtight condition.

  • * 1-thermometer good to 120 C, often candy thermometers will work.

  • * 1-Scales to measure out NaOH, or in a pinch use a metric teaspoon measure.

  • * 1-Litre volume measure, and something to measure out 250ml of methanol.

  • * 1-Bowl/container to mix the methanol and NaOH in.

  • * 1-Funnel

Ingredients

  • * 1 liter oil, new or used (New will be more reliable).

  • * 250 ml methanol. Used in some gas line anti-freeze and as the fuel in some racing cars and model airplanes.

  • * Container of NaOH (sodium hydroxide), also called Lye and caustic soda. Typically used to clean out sinks and drains.

The technique

If using waste oil, take one liter and heat to at least 120C to remove all water. If water is present the oil will spit and pop and carry on. If there is a lot of water this could get very violent, so be careful.

Once the water is gone (Oil becomes calm and there is no more spitting and popping) let the oil cool.

If you are using new oil from the bottle, just heat to around 55C after you make your methoxide as there should be no water.

Making the methoxide

Warning: Methoxide is a poison. Be careful not to breathe in the vapors. Wash away any splashes. Cartridge-based respirators will not filter-out methanol. If you are using new oil this will require about 4g NaOH (about half a slightly rounded metric teaspoon).

If you are using Used Oil, you should do a titration to determine the correct amount of NaOH, OR just try using 6-7 grams of NaOH (about 1 level metric teaspoon) and hope for the best. I have made hundreds of mini-batches of biodiesel from various types of oil using 6g NaOH and have NEVER had a failed batch. It is very probable that it will work for you too, but I do know of one person who had oil that was so used that it did not work.

NaOH and Methanol do not readily mix, so if you are doing it by hand, a bit of time and patience is required.

Don't sniff the fumes, mixing outside is recommended.

For quickest mixing, start with the methanol at JUST body temperature (not warm). As you mix, the temperature will increase substantially. This is normal. Make sure ALL the NaOH (lye) is dissolved. Hand mixing can be accomplished using a spoon to stir/crush the NaOH granules; OR placing methanol/NaOH in a glass bottle with a tight top and shaking/ swirling until ALL NaOH is dissolved. This may take 10 minutes or more.

Warning: The reaction between NaOH and methanol is exothermic, which means that it occurs spontaneously and produces heat. This is why the mixture warms up. In a tightly closed container, the release of heat will cause an increase of pressure. If too-large amounts are used in a too-weak container, there will be an explosion. Which could cause serious physical injury. Be careful with this technique.

After ALL the NaOH has dissolved, top up to 250ml with fresh methanol, as there may be some evaporation during mixing.

Making the Biodiesel

When the Oil's temperature has dropped below 60 C, use a funnel and pour the liter of oil into the dry 2 litre Dr Pepper bottle (in a pinch any other brand of bottle will do).

Take the mixture of methanol/NaOH (commonly called methoxide) and pour on top of the oil using the same funnel. Remove funnel.

Screw the top down TIGHT onto the bottle.

Shake vigorously for ten seconds/ 40 good shakes. NO significant pressure is generated during shaking.

Now place the bottle on a table and observe the oil change color from a "Light Chocolate milk to a rich, darker brown." Then, as if by magic, within 10 minutes the by-product (commonly referred to as glycerin) starts to settle out and form an increasing layer on the bottom of the bottle. Be sure to notice that you can see a very definite, slowly sinking line towards the top of the Biodiesel as the glycerol slowly settles.

Within an hour, most of the glycerol will be settled out. This is referred to as separation.

You now have a bottle containing lighter colored biodiesel on top of a layer of darker glycerol. Using this biodiesel recipe the biodiesel will be very cloudy, and it will take a day or two more for it to clear. Typically the bottom glycerine layer is about the same or a bit more than the amount of methanol used.

Congratulations! You have just made high-quality biodiesel fuel. Say goodbye to ExxonMobil & Co., forever. You don't need them anymore. You can make your own biodiesel.

There are as many biodiesel recipes as there are people to create them. Biodiesel recipes are limited only by your imagination. Like any recipe it should be modified to suit you, your biodiesel situation and your taste. This is meant as a starting point. Your biodiesel recipe journey should start here, not end here.
