oils available for process in my area are solid oils which after processing freeze at even moderate temperatures. I have been performing tests in my vehicle and find it acceptable to run 50% mix with pump diesel. The only time I tried a lower pump diesel percentage unfortunately coincided with an overnight frost and the following morning the car died after about 1/2 mile and took about 3 days to thaw! What would be a better option than pump derv to cut the biodiesel with to give it a wider temperature envelope? I have recently got a supply of pourable hydrogenated WVO but not in quantites that would allow me to run 100% biodiesel. I am currently processing the first 10 gallon batch and the quality of the oil seems poor requiring a LOT of lye to get the reaction moving. I ususally work on the 2 stage base/base method with 6.5g of lye per litre WVO and 25% methanol by volume to oil. This oil turned to an emulsion similar to that depicted on the 'foolproof' method page (http://journeytoforever.org/media/aleks/FP6.jpg) I was forced to add more methanol with a very high level of lye in it to get things 'brewing' Not sure if the problem is the quality of the oil or if the additives used to make it pourable are hindering things. If I can winterise the solid oils better, and get up to about 75% biodiesel I will be happier.
Any suggestions?
