Experiments by Neutral (infopop forum) indicate that viscosity of the fuel (a measure of conversion extent) continues to fall up to 30% methanol. If you use less, you just end up with more mono- and diglycerides in your fuel, and a higher viscosity. Whether that matters probably depends on your climate, your engine, your source of waste oil, and a lot of other unknowns. >2) What is the overall yield of the process.

About 100, provided you don't lose any in emulsion, precipitated tallow esters, etc. Again, many variables in this question. -K Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/ Please do NOT send Unsubscribe messages to the list address.
