Introduction: How to Make Biodiesel (fast and Easy Way)
hello, today we will see how to make multi purpose bio diesel. that can be used for cars but for heaters ,stoves or oil lamps too.
but we will not use the usual way. we will not use dangerous lye and methanol , but an easier way with no byproduct like glycerin.
we will use the solvent blending in wvo method .it is a lots easier and faster ,it can be done in micro batch or in larges quantities.
Step 1: WVO : Waste Vegetable Oil
first we will use vegetable oil in our biodiesel. in a blend of 80%.
it can be olive, sunflower ,palm ,grape,algae or any other vegetables.
it can be clear oil but wvo is more interesting.
the oil should be filtered first and all contaminant should be removed.
oil without animal fat inside is better.
in the case of wmo or waste motor oil, i think you should just stay away from it. it is dirty, full of chemicals and metal particles , it is dangerous to burn and can clog engines so we will not use it.
Step 2: Solvent
we will use solvent to thin the oil ,it will improve the biodiesel viscosity and stop it from gelling.
the solvent used will be : gasoline, white gas or turpentine. and will be blended at 20% to 30% in the biodiesel.
white gas (called too naphta, coleman fuel or essence F)is the cleaner burning of all solvant, but sadly is petroleum based.
regular unleaded gasoline is the perfect solvent for cars and the lowest priced but sadly it is petroleum based .
turpentine is the perfect vegetal solvent but has a strong pine smell.
note only one solvent will be blended at 20 to 30% too much solvent will make the biodiesel flammable and dangerous , not suitable for multi purpose use.
optional: you can add 2 to 3% of acetone for better thinning at very low temperature can help when gelling, but too much acetone can damage rubber.
acetone can be petroleum or vegetal based.
we will not use in the biodiesel blend regular diesel or kerosene mostly because of their low thinning power, they are not interesting until they are at least 50% blended in the mix.
Step 3: Final Result.
here are mix of 80% sunflower oil 20% white gas and 2%acetone .it is a very nice biodiesel , I'm mostly using it as an emergency lamps oil fuel in the cold.
the smell is different than regular diesel but it is as strong smelling.
the mix need to settle 24h at minimum before use, sometime impurities can be pushed out by the solvant and another filtering can be needed before use if there is some impurities.
