[Biofuel] %FFA of vegetable oil
Hi all I've seen several conflicting ratios for converting homebrewer titration results of # ml 0.1% NaOH solution to % FFA. This below is from Biofuel Systems in the UK http://www.biofuelsystems.com/. Can anyone confirm whether it's correct or not? How to determine percentage free fatty acid (%FFA) of vegetable oil / used cooking oil Add 10ml of oil to 100ml of isopropyl alchohol (propan-2-ol) Mix thoroughly until oil dissolves. Add a few drops of Universal Indicator solution (UI) Measure how much 0.025M sodium hydroxide solution (1g NaOH / 1 litre water) is required to neutralise the oil solution - ie. raise pH to 8 / turn UI blue/green While continually stirring this mixture, add the NaOH solution drop by drop until the mixture turns and remains green / blue. Note the number of millilitres (ml) of NaOH solution required to do this. In stoichiometric terms, 1 mole NaOH will neutralise 1 mole of oleic acid (OA) Firstly, determine how many moles of NaOH have been used Moles = molarity (mol/l) x volume (l) = [ molarity x volume (ml) ÷ 1000 ] Example If 10ml of NaOH solution was used Moles of NaOH = (molarity of solution x volume in ml) ÷ 1000 = (0.025 x 10) ÷ 1000 = 0.00025 moles of NaOH Therefore, the equivalent to 0.00025 moles of OA have been neutralised mass = moles x molecular weight (molecular weight of OA is 282.52 Daltons) mass of OA in 10ml sample = 0.00025 x 282.52 = 0.07063 = 0.7063g per 100ml of oil rounding to 2 decimal places, %FFA = 0.71 Put simply... %FFA = number ml 0.025M NaOH solution used x 0.07063 - Since most homebrewers use 1 ml of oil in 10 ml of isopropanol, that would be: %FFA = number ml 0.025M NaOH solution used x 0.7063 I guess blue/green Universal Indicator solution is the same as magenta phenolphthalein, no? Thanks!

[Biofuel] Canola biod and nitrogen oxides
Hello all A reviewer at Amazon.com of LILI's book How to make biodiesel commented: The parts I did read also left out important data, such that by using canola oil, nitrogen oxides actually decrease. http://www.amazon.com/How-make-biodiesel-Dan-Carter/dp/0954917103/ref=sr_1_7?ie=UTF8s=booksqid=1236596514sr=1-7 Do they really? Decrease below soy biodiesel levels I suppose, since the reviewer's an American. That doesn't seem to make sense to me. Can anyone confirm/explain it?

[Biofuel] Water-fuel hybrid
Hi folks There's a man offering to fit the water fuel conversion here. Does anyone have any experience of this kit?

Re: [Biofuel] Water-fuel hybrid
No actual experience, I'm afraid, but this does bear a certain resemblance to myriad other schemes and therefore puts me in mind of snake-oil. One of the photos shows a pair of billet-aluminium-looking canisters. I suspect that that is where the snakes are kept. I'm no chemist, but the chemistry lecture doesn't quite ring true even so, and the attribution of engine wear etc. to the presence of carbon in the fuel is just plain false. It seems to exploit the recently-amplified popular view of carbon as a sort of sticky black grime, on which much of the modern craze for molecule-counting (giving us your money will save x tonnes of virulent treacle) depends, together with vintage-era images of decoking a cylinder head with a hammer and chisel. I would therefore incline not to take this thing seriously.

Re: [Biofuel] Water-fuel hybrid
James, there could be a germ of validity in this. I had a quick look at the site, and this is not one of the dozens of sites that talks about water as a sole fuel for an internal combustion engine. (That concept is bunk in my opinion.) The concept here is that you use surplus energy from the electrical system to electrolyse distilled water into hydrogen and oxygen and then eject the generated hydrogen into the combustion process. A bit of an in-situ fuel upgrader. I am aware of a company that was installing such units on large trucks and had testimonials from fleet operators with what appeared to be objective data to support their claims. (Today, their Web site does not appear to be working - www.chechfi.ca. Perhaps they have succumbed to low oil prices.) However, there are some caveats. It has to be done right to get beneficial results, and that's non-trivial. You have to use distilled water. In some places, that's more expensive than gasoline / petrol. The water has to be kept from freezing, or the system is non-functional. The gains are variable, and dependent on the engine and fuel being used. You need to travel a lot of kilometres / miles to recoup your investment, and that will vary based on the price of the fuel being displaced. The company I referenced above focused on long-haul trucks because that's the niche where the investment made sense - when gasoline was over Cdn$1/litre. This will not get you off the primary fuel - it only promises to reduce the amount of that fuel being used. IIRC, the CHECHFI were reporting gains of 10-15% in fuel economy. I am not a fan of anecdotal reports, especially only after a short time of operation in the modified mode and no evidence of detailed records of pre-conversion data. I am a believer in A-B-A testing - that is, detailed records before the modification, after the modification, and again after the modification has been removed / deactivated. (BTW, I have offered to do such testing on my own vehicles for several firms offering magic magnets that were supposed to improve fuel economy, but none have taken me up on it.) BTW, most drivers can achieve better gains than that simply by changing their driver behaviour a bit and doing some common sense things around their vehicle maintenance regime. Have a look at my Saving Fuel page for tips. http://www.econogics.com/en/savefuel.htm In short, my advice is to be highly skeptical about such devices, do your homework including a realistic cost-benefit analysis (and considering how long you expect to be using this vehicle), check references, and get a written guarantee regarding fuel savings to be obtained. Do all the other fuel saving things on my fuel savings page that seem appropriate first. Once that has been done, use your documented fuel usage data as the baseline for discussions with this firm and the guarantee on fuel savings to be had. I strongly recommend use of fuel usage logs and even better, fuel consumption computers. I had one in a car we used about 15 years ago, and it revealed some fascinating things about relative fuel consumption across different drivers in the same vehicle. With oil prices at US$40 a barrel or thereabouts, I can't imagine that this set-up would be cost-effective for a typical private car.
