Biodiesel is an environment-friendly diesel that comes from vegetable oil and diesel combination. It makes your engine work efficiently and does not harm the air you breath. Cost wise, biodiesel is quite cheaper as compared with the actual diesel. Because it is less costly, how do you think if you will learn how to make biodiesel yourself?
Of course, learning how to make biodiesel may take sometime. However, based on testimonies of people who actually make biodiesel, it is actually simple. Of course, patience is necessary including safety precautions but in general making biodiesel is easier than you think.
What you will need to make biodiesel?
- 1 liter of supermarket vegetable oil. Of course, you can use used oil later but in your first few batches, it is recommended that you use new vegetable oil.
- 200 ml of pure methanol. Pure methanol means 99% pure at the minimum check the label when you buy your methanol.
- Lye catalyst, use potassium hydroxide.
- Blender
- Measuring beakers for methanol and oil
- Half-liter translucent white HDPE container with bung and screw on cap.
- 2 funnels, make sure it fits in the HDPE container
- 3 2-litter PET bottles, 1 for settling and the 2 for washing
- Thermometer
Make sure you accurately measure all the ingredients, your success if dependent on them. Steps on how to make biodiesel
- Wipe dry all the equipments you are going to use.
- Mix lye and methanol. Quickly transfer your methanol into the HDPE container using the funnel. Carefully add the lye to the methanol and screw the cap tightly. Mix them by rolling the bottle a few times. Do not shake the mixture; it may be dangerous.
- Pre-heat the oil at 55 degrees centigrade, and put it in the blender.
- Add the methanol mixture to the oil in the blender.
- Blend the mixture at low speed for at least 20 minutes.
- Transfer the mixture in the PET bottle intended for settling.
- Leave for 12 to 24 hours.
Upon settling, the mixture will have a darker bottom and a lighter top. The lighter mixture is the biodiesel.
- Transfer the mixture into the washing bottle and add water, bubble wash for several times.
There you have it your very own biodiesel. Test your product, make sure that it works the way you want it. Make another batch if necessary test again.

How to Use Biodiesel Processor for Producing Biodiesel From Vegetable Oil
A biodiesel processor is a combination reaction vessel. It is used for producing biodiesel from vegetable oil.
An industrial processor is very much considered convenient for production volumes, which can’t produce more than10,000 t/year. The reaction and distillation process of the alcohol is a batch processing. The decantation use to happen continuously.
In the industry, a static mixer is being used with the esterification catalyst called sulphuric acid and then methanol and vegetable oil are mixed. The reactor is used for esterfication of free fatty acids. Where as in another static mixer, an alkaline catalyst generally potassium hydroxide is getting used, this is added to the methanol-oil mix for the transesterfication.
Now in the Second reactor, the process is called transesterfication occurs. While in the third mixer, various outcomes from a reaction are biodiesel, glycerol and methanol solvent. It is being nullified by introducing a simple mineral acid. The alcohol being separated in flash vaporizer called as distillation unit. The condensed Vapors of methanol are sent to the reception unit for introducing again in the cycle.
Now the remaining products in the flash vaporizer namely, biodiesel, glycerol, salts and water, are sent to continuous decanter, which separate biodiesel from rest of the by-products. The light phase which is getting created in the decanter is en tot the storage tank and remaining heavy phase is sent to another storage tank for latter purification. After this phase, it contains 80 to 90% pure glycerol, water and salts.
Biodiesel and glycerin purification ca be done in high vacuum evaporators. There is typical design called as wiped film evaporator, where products used to be clearly differentiated from various salts by thermal as well as mechanical methods.
The quantity of raw material which is required to produce 1000kg of biodiesel and 112 kg of glycerol.
It requires 1030kg of refined vegetable oil. It requires 103kg of Methanol. Catalyst of quantity 6.2kg used in process of biodiesel is sodium hydroxide or potassium hydroxide. Mineral acid required quantity is 6kg
There are some other services which should be make available like,
Cooling water service 20m
Steam 350kg
Electricity required 50KWh
Nitrogen required 3.2m
If you are making biodiesel at home, you should use any triglyceride fat or animal tallow or vegetable oil. You should have a strong base namely, sodium hydroxide or potassium hydroxide, also pure alcohol. You should have longer chain alcohol; it must be longer than isopropyl alcohol. You can use oil for processing which is often obtained in restaurants.
There are different methods for producing biodiesel. It is generally produced in small batch processors in the garage. But now some used to adapted processors to fit at the back of vans. It is transportable. One of the major difficulty being Dealt by various biodiesel homebrewers is just to make a mid scale biodiesel processors sufficiently very simple to cheap, safe and easy to make appropriate.

What is hydrochloric acid + potassium hydroxide?
What's hydroxide? how is it made? what's the difference between potassium hydroxide and potassium oxide?
A hydroxide refers to the OH- polyatomic ion and is formed when an oxygen makes a covalent bond with one hydrogen (however you would not see such ions free in nature as they would more probably be in compounds).
Potassium hydroxide (KOH) is formed when Potassium forms ionic bonds with OH- ions while Potassium Oxide (K2O) is formed when potassium forms ionic bonds with the Oxide (O2-) ions.
Hydrochloric acid + Potassium Hydroxide ---> Potassium Chloride + Water
i.e. HCl(aq) + KOH (aq) ----> KCl (aq) + H2O (l)
This reaction is a neutralization reaction and occurs when an acid (HCl) reacts with a base (KOH).
