Hi Anton >An acquaintance did a test and got about %4 back from a batch using %16 >methanol. I assume then that the bd reaction only uses 10-12 percent.
Other sources confirm that - but, unless you have a very well controlled set-up, as in a lab, you need to use the extra to get your reaction and complete it, then reclaim any excess afterwards. >this >is not scientific, but I think that since you are not only making your >glycerin non poisomous, and reusing the "waste" methanol, it is worth the >effort even at smaller returns than that. Also, if you are recovering the >methanol, you can use more of it for a better reaction without a cost >penalty. Yes, I'm sure that's the best way to look at it. Producing quality fuel is more important than saving a little methanol. >What does anyone have to say about pretreating the biodiesel with the >leftover weaste glycerin with the methanol still init? mix the glyc, whicvh >has meth and NAOH, then do a reaction with a corresponding lesser amount of >reactants... Keep going, you're doing very well. I can tell you it works well if you get it right, but I'm not free to tell you any more than that. Be encouraged!
