So far I have made two batches of fuel. Both times I had some emulsion during the first wash. I drained the emulsion off with the wash water and rewashed the remaining fuel until it was clear then put it in my 55 gallon drum do dry. Befor I put it into my new turbo diesel suburban, I thought I would do two more final test. I pumped some fuel into a jar, added water and shook it up. The water seperated in about ten minutes with clear fuel on top and clean water on the bottom. so far so good. My second test was to re-process the fuel like virgin oil. I mixed 3.5 grams of lye with 200ml of methanol, put this mix in the blender for a minute then added 1000ml of my finished diesel fuel.and mixed for 15 more minutes. After letting this settle for two hours I have cloudy fuel on top and about one inch of what looks like clear fuel on the bottom.. The bottom layer is not dark like glycerine but clear like washed fuel. When you re-process already processed biodiesel, what happens to the methoxide? does it seperate to the top or bottom or does it stay mixed with the fuel?
