Hi everybody, now I used the correct amount of NaOH and my 2nd batch seems to be much better :-) The result can be found on: http://users.pandora.be/thunderbirdIII/bio/batch2.jpg
On the bottom, you can see some black marks, to measure how fast the glycerol is setteling. From bottom to the top: mark 1: 5 min mark 2: 15 min mark 3: 33 min mark 4: 55 min Now it seems to be stable (now I'm at 90 min), but I was wondering if the colours are normal for unused rapeseed oil. On the top, I'm getting a layer which is dark yellow, the biggest layer in between is light yellow (with some "fog" in it as you can see on the picture) and at the bottom the glycerol which is more or less brown. Another question: does somebody knows some simple tests that I can execute to check my biodiesel? I'm not really sure if I can use this in my car :) Regards, Gregory _______________________________________________ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo.cgi/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/
