What are you trying to make? First step is to make a litterature study. There you will find the procedures needed for the route you select. Then you can modify the steps to make the process better.
There are a total steps that would let you have a final product of biofuel that you can use in your car, including Finding an oil source, Testing the oil, Filtering the oil, Making a test batch, Obtaining production equipment, Obtaining chemicals, Pre-Treating the oil, and final products
Based on the rawmaterial as you mentioned, bioethanol can be produced. Bioethanol is a kind of biofuel which is an alternative to gasoline. Frist of all, you must clean the rawmaterial by a simple washing with 5% KMNO4 solution followed by distilled water as a sterilization step. Then, dissolve the rawmaterial in a aqueous medium after the rawmerital was chopped. This speedup the fermentation process. Then the medium pH was reduced approximately to 5, which enhance, acid digestion. Add some suger and yeast into the medium and facilitate an anerobic condition. Keep the mixture for 7 days to happen fermentation process. Therefore, filter the solution and distillate the sample at 80°C under a vaccume condition.
Triple distillate further enhaned bioethanol yeild.
