Poor Conversion

[Eddie Biofuels Forum Newbie Find all posts View Profile Close Eddie]

Hi again, i just did a 60 litre batch and after the conversion rate test (brilliant) got the bad news that it was not a particlarly good conversion, now, as i am 99% sure that i used enough KOH (this time), i was wondering what other factors could contribute to the poor conversion.. and what should i do with it now? is it still usable, or should i reprocess it?
i am champion at making 1 litre batches,..hah.. they turn out really well, mabey i should make lots and lots of them eh?
thanks

Re: Poor Conversion

Hello Eddie,

Poor conversion can be caused by,

Not enough NaOH/KOH
Poor quality NaOH/KOH
Not enough methanol
Poor quality methanol
Not enough time mixing for the temperature the reaction is performed at..
Poor quality mixing equipment.
Too much water in the reaction.

Re: Poor Conversion

ok thanks tilly, the fact that my one litre batches work well leads me to think its prolly the reactor, or not enough mixing perhaps. i will modify a few bits and try again.. and again.. hah.
