Re: [Biofuel] Reprocessing question
What do you mean by 90.5% KOH ? If the rest (9.5%) is water, that is where your problem is. With water, oil and KOH you have the right recepy to make soap. Try to get the KOH or NaOH as pure as you can get it. Succes. Metvriendelijke groet,Pieter Koole - Original Message - From: Bill Clark To: Biofuel@sustainablelists.org Sent: Monday, June 27, 2005 7:34 PM Subject: [Biofuel] Reprocessing question Hi Keith and all, I made a 200 gallon batch of biodiesel last Friday. I used 200 gallons of wvo, 40 gallons of methanol, and 16.5 lbs of 90.5% anhydrous KOH from a titration of 4.5 g/L. After draining off the glycerine I took a 400 ml sample and performed a shake test.I got an emulsion. I added a couple of grains of calcium chloride and a thimble of vinegar and got perfect separation in about 10 minutes. As you know, I have addressed the question of soft water in the wash and while the addition of calcium chloride and vinegar have yet to produce a poor result, I am troubled by this initial emulsion formation using plain water. Today I took 1 litre od the biodiesel and reprocessed it. I used 200 ml of methanol and 5.4 grams of 90.5% KOH, preheated the oil to 120 F and blended for 20 minutes. After 1 hour there was no detectable settling of anything. The biodiesel remains in one phase that is slightly darker than the original biodiesel and somewhat cloudy. Does anyone think that I have a concern here or am I just being paranoid?

Pieter What do you mean by 90.5% KOH ? If the rest (9.5%) is water, that is where your problem is. With water, oil and KOH you have the right recepy to make soap. Try to get the KOH or NaOH as pure as you can get it. Succes. Lab-grade KOH assays at 92% at most, it doesn't get any higher than that. It varies between 85% and 92%, and it's a superior catalyst to NaOH. It's what most commercial biodiesel operations use and it doesn't make soap (unless you do it all wrong). Pieter, I've several times referred you to these pages, all this stuff is explained there and much more: http://journeytoforever.org/biodiesel_make.html Make your own biodiesel http://journeytoforever.org/biodiesel_make2.html Make your own biodiesel - page 2 I really wish you'd read them, then you wouldn't be making basic mistakes like this and asking whether phenolphthalein is the same as phenol red and so on.
