Re: [Biofuel] Deacidification
Hi Keith I have done a 1L test . Fortunatly I re titrated after deacidification and found that the oil had dropped from 7mls to 1ml titration so I added this plus the 3.5. in the 25% methanol, and it came up nice and clear after three washes. Cheers Ian :-) You're on your way Ian, good news!

Re: [Biofuel] Deacidification
Hi Todd, There is a method of making biodiesel where all feedstock is converted to soap, then chemically cracked to 100% FFAs and esterified to yield ~100% biodiesel. But it's doubtful that you have the set up for something that involved at any moderate scale. What methode is that ?

Re: [Biofuel] Deacidification
How stupid am I ?? When we remove the FFA's , we have only left the FFA's connected to a glyc molecule. Right so far ? The next step we do with the single stage is, breaking the fatty acids of the glyc molecule, which produces FFA's. (Not) right so far ? Next we connect a meth. molecule on top of the FFA's. So why do we have to remove the FFA's at the first place ?

Re: [Biofuel] Deacidification
Ian, What are you deacidifying your oil with and how? Adding lye or similar caustic in the absence of methanol is a sure fire way to manufacture soap, just about the last thing you want if your eventual end product is going to be biodiesel. There is a method of making biodiesel where all feedstock is converted to soap, then chemically cracked to 100% FFAs and esterified to yield ~100% biodiesel.

Re: [Biofuel] deacidification
Hello Ian Hi Keith This is probably the best stuff avalable in my small town, as it is from a food shop renound for quality food. :-) It comes as a surprise to quite a lot of biodieselers when they start titrating restaurant oil and quickly find out which ones really produce quality food. 6ml 0.1% NaOH solution oil is not the product of a quality restaurant, sorry to say. Yes I did mean deacidification as per JTF site. I have 80 litres in 4 drums, I took three samples heated them to test for water There's probably some water in oil like that. The higher the titration level the more difficulty water will cause. and carried out the test three times I even tried different isoprpyl as some of what I had was quite old, but still the same result. I then tested some oil from a friends home frier and found it to be around 3.5grpl, About the upper limit, beyond that novices start having problems. (For his sake rather than yours, I'd suggest you tell your friend to change his oil more often or not to make it so hot.) them a further test on brand new SVO and only 1 drop caused a change to pink? Given that my testing is accurate Probably it's accurate. should I persisit with single stage or try deacidification? The only 2 things that I question of my testing is the 1/1000 mixture was cold, although the test was carried out with the beaker standing in warm water and the phenolphalein was made up with Ethanol? I think it always is. It should be okay as long as it's not old. For the 0.1% NaOH solution, next time pour some into another beaker and stand that in warm water too. Anyway, 6ml titration oil is feasible once you have some experience, there shouldn't be any need to deacidify it. Try deacidifying it if you like, it takes a little practice (gently!), but even if it works it will only have added another variable as an obstacle in your learning curve. I'm sorry, I've lost track - did you start with virgin oil tests? If not, I suggest you go back and do that a few times: http://journeytoforever.org/biodiesel_make.html#start Then try the 9.5 gm/litre WVO. Do small 1-litre test batches. If you don't succeed, then mix virgin oil with the WVO until you've reduced the titration result to say 2.5 to 3 ml and try that. If you haven't got a blender you could rig one of these or something similar: http://journeytoforever.org/biodiesel_processor7.html Test-batch mini-processor Or you can use PET bottles - mix the methoxide first, do it this way: Methoxide the easy way http://journeytoforever.org/biodiesel_aleksnew.html#easymeth Pre-heat the oil to 55 deg C (131 deg F), funnel it into the PET bottle, add the methoxide, screw the lid on tightly and shake violently for a minute or so. Then stand it in hot water and maintain the temperature at 55 deg C. Shake it again hard every five minutes, continue for at least an hour, preferably two hours. Please remember that your main goal isn't to process that 80 litres of oil, it's to learn how to make high-quality biodiesel. If you go about it that way you'll get better results with that oil or any oil. Best wishes Keith Your thoughts would be appreciated Cheers Ian Hello Ian Hi Guys I've just tested the WVO I've managed to obtain and tested out at 6grpl this plus 3.5 makes 9.5. Is this a candidate for deacidification? What do you mean by deacidification? Do you mean using an acid-base process instead of a single-stage base process, or do you mean this, or something similar? Deacidifying WVO http://journeytoforever.org/biodiesel_make2.html#deacid Deacidification is a standard step in processing raw (new) oils for sale and consumption. The deacidifying process above is basically the same but without the need for a centrifuge. If you mean an acid-base process, any oil is a good candidate for that. Anyway, oil titrating at 6 g/l is probably borderline for a novice attempting his first test batch with WVO. Standard WVO, if there is such a thing, is usually considered as around 3-3.5 titration. Try it if you like but you might struggle. Strictly speaking, it shouldn't be 6grpl but 6 ml of 0.1% NaOH solution, which indeed translates to 9.5 grpl. How did you titrate it?
