Christian, Is there a way to calculate how much catalyst would be needed for how much a reaction time. The reason for washing is to get rid of the catalyst in the newly reacted BD and lower the ph right? so if we can use lesser catalyst then washing might not be necessary. As for the excess methanol/ethanol, airing it for some time takes care of that.

Maybe I was just unlucky, but you should try to check the content of water in your BD as the presence of it could be harmful to the motor. I«ve heard some people use pure methanol directly to get a BD pure enough to use without washing... (I don«t know how good this might be). My BD was very transparent. Even more crystaline than diesel fuel bought from my near by gas station. > >Comments welcome. > >Regards, > >Christian > > >[Non-text portions of this message have been removed] > > >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. >To unsubscribe, send an email to: >[EMAIL PROTECTED] > >Your use of Yahoo!
