Homebrew Diesel

Biodiesel is arguably the best option for a petroleum fuel. It can be utilized as fuel in diesel powered engines. The reason for it being called 'biodiesel' is that it is prepared mainly from biodegradable material. You are also able to use it in its pure form or blend it with regular petroleum diesel. Homebrew diesel is simple to prepare. Still you should take the proper precautions by getting the proper equipments as well as the suitable clothing. The following is the method needed to prepare homebrew diesel with the help of the fresh vegetable cooking oil, but before you begin you will need the following things; * A blender with a large glass jar; * A weight measurement scale set; * One quart measuring jar;

* One hand pump; * Fresh vegetable oil; * One other liquid measuring cup; * Sodium hydroxide; * Methanol; Now before commencing, let all the material heat to at least 1310 F.

Then put on the necessary protective clothing like the gloves, goggles, respirator, and so on. Pour one cup of methanol into the blender. Take 3.4 grams of sodium hydroxide and add this to the methanol in the blender. Cover the blender and blend the mixture for about 5 minutes or so at low speed. You will now find that the resultant mixture in the blender is sodium methoxide. This is a very strong base and you should avoid coming in contact with this mixture. Now, add one quart of new vegetable cooking oil into the mixture in the blender and with all due safety precautions, blend them at a low speed for half an hour. Now let the mixture stand at normal room temperature for a minimum of 8 hours. You will find that the mixture has now separated into two layers. One is a light coloured layer, and is floating on top of the other layer, a dark coloured layer. The dark coloured layer is called the glycerol, while the other lighter fluid layer is the biodiesel. You can now pump out the diesel using the hand pump. Homebrew diesel is quite easy to prepare and it also gives you a further option. You can prepare the biodiesel with the help of the used or waste biodiesel. The waste oil is more acidic than the fresh vegetable oil and hence can be much more efficient. Because of the presence of the higher fatty acids, the amount of catalyst required is considerably more. To calculate how much of the catalyst is required, you will have to do a titration. After the titration, you can work out the amount of the catalyst required and then you can proceed.

You will have to utilize all of the sodium hydroxide. When this is done continue with the same steps to prepare the biodiesel as followed in the method used to prepare the biodiesel from fresh cooking oil.At the completion of the process, you will find that the there are more layers present than in the first process. The layer which is white in colour and is present between the glycerol and the diesel is the soap. It is a manufacturing by product and occurs even if there is minute amount of water in the oil.
