How to Make Bio Diesel

Titration of Free Fatty Acids.
Measure Free Fatty Acid content of your oil: Mix 1 ml oil with 10 ml Isopropyl alcohol = 2 drops phenolthalian solution (available in a hobby shop chemistry set suppliers). Drop wise add 0.1% lye solution ( 1 gm lye in one litre water ) until the solution stays pink for 10 seconds. (20 drops = 1 ml) Record the millilitres of 0.1% lye solution used.

You will need 200 ml of methanol per litre of Hemp Seed oil. Methanol may be purchased as Drigas available at most automotive stores, read the label for methanol. Also Methanol is available from racing stores. Avoid hardware store methanol (wood alcohol) as it may contain excessive water content.

Sodium Methoxide
For each liter of hemp seed oil you need one gram of granular solid lye for each ml of 0.1% lye solution used in titration of free fatty acids plus 3.5 grams. Completely dissolve the proper amount of Lye in the methanol (Red Devil Lye can be purchased from the Grocery Store). This combined mixture makes sodium methoxide.

The type of mixer depends on the size of the batch. A blender works fine for a small batch. An electric drill and paint mixer on an extended shaft works well in a 5 gallon bucket. An electric light dimmer switch provides a good speed control.

Once the lye catalyst is dissolved completely so that there is no sediment, then the oil may be added to the methanol lye mixture while mixing continuously. At first the mixture becomes thicker, then thinner as the reaction proceeds. Collect samples every 5 minutes with an eye dropper into a test tube or clear container. The Mixture will separate into a light top layer of bio diesel and a darker bottom layer of glycerin, soap and catalyst. Continued mixing 30 – 60 minutes until the yield remains constant. Then stop mixing. Go have lunch. When you come back it will have settled into two distinct layers. You have just made what could be the fuel of the future for a self reliant society. Let the mixture settle for at least 8 hours. Pour off and save the bio diesel top layer into another container. A clear funnel bottomed container is helpful.

The raw biodiesel that you have just produced may have some catalyst, alcohol, and glycerin remaining which could cause engine problems, so for long term engine reliability this raw fuel should be rinsed with water. Gently at first then more vigorously rinse with water until the rinse water is clear and the pH of the rinse water is the same pH as the supply water. Settle, Decant.

Water in the bio Diesel makes cloudy so it must be carefully heated. At 100 C most of the water coalesces and falls to the bottom. This water must be completely removed from the bottom of the container before heating to higher temperature.

CAUTION! Wear protective clothing and eyewear.


Once all water has been removed then heat the bio diesel to 300 f (150 c) to complete dryness. Cool, filter, and store bio diesel in a well marked dry closed container. 100% HEMP DIESEL FUEL (HEMP OIL METHYL ESTER – HOME FUEL)

This fuel may be mixed in any ratio with petroleum diesel. Dynamometer tests indicate full power output with up to 75% reduction in soot and particulates. No engine modification is needed to burn bio diesel fuel.

Other Oil Feed stocks

Hemp Seed Oil at present is too expensive to drive across the country. That is not the object of this article. Our propose is to demonstrate proof of feasibility of this fuel concept. The time is now to give hemp a chance. The small quantities of Hemp Diesel Fuel can play a powerful role in educating ourselves and the policy makers about the hope in hemp.

For other readers the question will be raised. What else can I use can I use as a feedstock that is cheaper between now and domestic hemp seed crops? Soy, Sunflower, Canola, and Safflower oils are being used in field testing programs right now. The ground support vehicles at the Kansas City Airport are operating on Soya diesel. Lincoln Nebraska City busses are operating on Bio Diesel.

Go ahead practice your fuel making technique on any vegetable oil available. The most important change for us may start within ourselves. Let us get on with the curriculum.

A four woman video crew recently traveled across the country from new York city to San Francisco in a Diesel Chevy Van fueled by French Fryer Bio Diesel. They would drive past the gas pumps and the diesel pumps. They would drive around the back of the burger joint and ask for drippings from the the fryer in day-glow pink waitress outfits. The video is both entertaining and informative. Video is both available from Original Sources (303) 237 – 3579.



This is my answer to April: There is not any favourable medical response which affirms a link between the gateway drugs and any other type of psychoactive substances, our objective is to push to the curiosity, to have a little consciousness about drugs and hemp especially, ‘cos it is well-known that it has an energy importance, absolutely to be evaluated, don’t you think? The barrel of crude oil price it is near two a hundred dollars,and my country, Italy, it was the third country in the world for hemp export, you know?

Without omitting his absolute medical importance, even recognized in a few American states.

However, talking about the data provided on, I only tell you that in Italy the “rehabilitation” (control urines and hair, guide document suspension, etc..) can begin if you are in 0.16 gram Hemp possession. And here the question: are you absolutely sure which is not an association with profit purpose?

It’s just a question, don’t misunderstand the answer tone, I accept any opinion or discussion. Please, link me what you have read and if you want come back on this blog, it will be a pleasure to talk still to you.

Thank you and see ya šŸ˜€

    Hemp biomass can also be a great fuel when dried and gasified. Here is a link to a video that better explains it:
