The best alternative for petroleum diesel is homemade; a convenient and inexpensive alternative made by converting vegetable oil. Nearly all the major European vehicle makers now provide their cars with warranties on the use of a pure form of biodiesel. People have begun to produce fuel for themselves in their own homes. No negative effects from this harmless process have yet been heard of.
You only need these three things to make biodiesel in your own home:
* 1 liter of pure, unused vegetable cooking oil
* 250 ml of pure methanol
* Either sodium hydroxide
(lye) or potassium hydroxide
* An electric blender that has a pitcher made of glass
* A set of scales that can measure with precision, down to 0.You will need, 1 liter high density polyethylene container, 2 bottles for settling, duct tape, and a thermometer. Be sure to keep all the equipment clean and dry. The steps to making biodiesel:
Always wear the proper personal protective equipment ensuring that no skin is left exposed, certified safety glasses and the proper breathing devices. Be very cautious as you perform each step. Extreme care should be taken in handling the harsh chemicals used in the process. Be sure to look and see that all the pieces of the blender are in satisfactory condition. You need to be sure that your blender is tightly sealed and that all of its components are clean and dried off.
Before pouring oil into blender, heat it to 550 C. At this point, the sodium or potassium methoxide that has been prepared must be carefully transferred to the blender from the polyethylene container. After sealing the blender, spin the mixture on low for about half an hour; it is important to maintain a consistent speed and temperature.
At the instant the process is complete, the mixture should be carefully decanted into a mini-processor. After completing the process, let the mixture sit for 12 hours or up to one day. You will then notice there are two separate layers to the bottle that the liquid is collected in. Two fluids will emerge, a dark-colored glycerin byproduct and a separate yellow fluid. The upper layer is the biodiesel. Though generally a pale yellow, the exact color of the created fuel depends upon the nature of the oil used. It doesn't matter if it's cloudy or clear. The longer it sets, the clearer it gets.
A wash test needs to be taken next. Only after it passes through wash testing successfully, may you then wash the remaining biodiesel.
