    Biodiesel

    Hi people, I'm looking into biodiesel and cannot find for the life of me find out how much fuel you could reasonably expect to make out of a 44 gallons of used vegetable oil. Any help or info would be greatly appreciated.

    Start with 200 litres of oil. Add 20% of oil volume in methanol. Bank on 80% yield from your 240 liters of mix.

    Thanks Andrew. Do you have much experience with this. Do you know a good kit to start with?

    Hi Ctins,
    There's plenty of info on the net re Bio-Diesel, if you wan't to produce good quality fuel, look at "Mike Pelly's two stage " method, this converts all the oil to fuel, whereis a single crack will only react about 75% of the oil ,leaving 25% raw veggie oil in your fuel. The two stage method makes great fuel and if done correctly,then washed and dried, can be used in any diesel engine.!, as long as components such as filters and lines are bio compatable
    Cheers Gregg.

    Be careful with Biodiesel made from vegie oil. The mice love it. When I was making and using it I had the rubber fuel lines of my D1 eaten out. Also it has to be let stand for several weeks to let the water settle out. I learnt the hard way and had to have the fuel pump rebuilt. I gave it away as the used vegie oil became too hard to source. When I changed over to a D3 they specify NO Boidiesel. I am not sure why.
    I am currently looking into the Millettia Pinnata (Diesel Tree). The seeds can be cold pressed and the resulting oil extracted is suppost to be able to be used in diesel engines with no further processing only filtering. Time will tell.

    Start here, do lots of reading...

    Forums

    Or, going right back to basics and nice easy way to get started...

    World Famous Dr Pepper Technique (Pat Pend) - Topic

    Much of the biodiesel info is AUSTRALIAN in origin, despite what you might think after reading some American sites. - Check the above site and go way back in time/history to see what I mean. "Tilly" and "Neutral" are two of the Very Useful & Wise contributors, with "Biocruiser" being the inventor of the Mist Washing system.

    Bottom lines... Filter, remove water from feedstock, titrate, use sufficient methanol, mix furiously.... and water-wash/dry/filter the end result.
    The best quality (met and exceeded all the European standards) bio I've ever seen was made in a single reaction, carefully bubble-washed, dried and filtered.


    <James in Perth.>

    I used to make batches from 200 litres oil, 50 litres methanol and would end up with (Very roughly) between 160 and 190 litres of 'perfect' biodiesel.
    - Yield depended on oil quality and type (canola, sunflower, cottonseed and the dreaded palm-oil...) Also waste, leaks, spillages and how extra-fussy I was !!!

    You would not put Pongamia oil in your D3 you WILL have big trouble! Pongamia oil cold pressed then filtered can be used directly in an old tech diesel engine with no ill effects.
    I have spent the last 6 years researching Pongamia oil and its uses & this is the future in BioFuel.

    Watch this space!

    Didge,

    One Hectare of the Diesel trees will produce around 5000Lt of Bio-Diesel every year for 70 years.

    Cheers

    I've heard so much about Biodiesel but never tried it for my car. I'm afraid it can harm engine or something else. But recipe sound really cheap and easy, even easier then I've read at fuel review by evolutionwriters essay writing, so maybe I'll try it. Thank you for the topic.

    Barnawartha biodiesel plant bounces back to life, as industry calls for more government support - ABC News (Australian Broadcasting Corporation)

    They are going to start making Biodiesel in commercial quantities in Aus again. I wonder if Freedom Fuels will stock the B-20 again?
