How do you make biodiesel out of used cooking oil? What are the ingredients used as well as the procedures?

I'm planning to buy a Mercedes-Benz 300D and I want to use biodiesel to run it. How do I do that?How do you make biodiesel out of used cooking oil? What are the ingredients used as well as the procedures?
Unfortuantely, it is a bit more complicated than Marjorie makes it sound. You cannot seperate cooking oil into biodiesel and glycerine buy simply heating it up. Biodiesel is a compound know as methyl-esters or ethyl-esters, the distinction coming from which alcohol you use with your catalyst. In order to produce biodiesel you have to break the chemical bond in the oil. Below I will outline the process. If you want more specifics, please email me and I will be happy to send them to you.





1 Collect used oil


2 dry the oil- Heat to a temperature greater than 212degrees.


3 Titrate the oil. you will need to know the ph of your oil in order to use the right amount of catalyst


4 Mix Methanol or Ethanol with Cataylst (NaOH). Produce Methoxide


5 Mix with oil for aprox 1-2 hrs.


6 pump into seperating tank takes aprox 24 hrs to settle out.


7 pump the biodiesel into a water wash tank. let settle again.


8 pump into storage tank or your fuel tank.





I have been making biodiesel for the past 8 years with various rigs that I have made myself. The simplist was 3) 55 gallon drums, and old water heater and 2) water pumps from habor frieght. I use 100% in my truck and then mix a 55 gallon drum into my heating oil tank.





My final cost per gallon is about $.50 per gallon not counting my labor and the propane I use to dry the oil.How do you make biodiesel out of used cooking oil? What are the ingredients used as well as the procedures?
pour the oil (new or used) into a NEW clean hot water heater.


Let it heat and sit for a day or 2.





The oil will separate.


The oil goes to the bottom, the glycerine to the top (or the other way around)


Separate the 2.


Strain the oil thru a filter


You can now use the oil in the PROPERLY ADJUSTED diesel engine.


The glycerine can be sold to a cosmetics co.
