Hi Pablo >HI everybody and Bob and JJN specially, > >I have made the porr man´s tritation process with tallow.
Fresh tallow or used tallow? If it's used tallow did you titrate it or just use the bracket tests? >I did apply for the experiment an equivalent of 300mL of methanol >per liter, and 4.5, 5.0, 5.5, 6.0, 6.5, 7.0 and 7.5 of KOH.

What strength of KOH are you using?

Well, if you want to waste a lot of time and risk oxidising your fuel you can use bubble-washing. I suggest you read this whole page first: http://journeytoforever.org/biodiesel_bubblewash.html Washing Best Keith >Thanks > >Pablo _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
