[biofuel] Re: how to modify a diesel engine for biogas fuel
hi all i want to know how to modify a diesel engine to work on dual fuel(BIOGAS AND DIESEL). kindly forward the links from where i can find the details. Bazeeth Ahamed --- Keith Addison [EMAIL PROTECTED] wrote: Hello Theo We are interested in planting jatropha curcas for producing our own biodiesel and have found quite a bit of information on the net but a lot of it is conflicting. So we have a lot of questions that we need answering and would appreciate any help in this regard. We are also looking for a place to buy seeds, as there doesnt seem to be place where we can purchase in South Africa. 1. How much oil can we conservatively expect per hectare? 2. Do cuttings give a lower yield than seedlings/seeds and does this last over the life span of the tree? 3. What is the ideal spacing for planting and what are the best conditions for growing and planting? 4. How long does it take for the plant to yield nuts and for how long will it produce? 5. How often does the tree bear fruit? 6. Is it necessary to irrigate to get the maximum yield? 7. Must we protect the plant against specific pests and diseases? 8. What can we do with the remains of the nuts after pressing them for oil? 9. How much biodiesel can we expect to get out of processed oil? 1. Why do you want to plant jatropha? High yield? 2. Why do you want to plant a monocrop? Monocrops aren't sustainable - you'd want to produce sustainable biofuels via unsustainable ag methods? Anyway, do an archive search for jatropha (without the quotes), there's a lot of information there: http://infoarchive.net/sgroup/BIOFUEL/ Including this: Jatropha curcas is a good option, but there are many other good options. The idea that it's the best option just doesn't take into account how development projects work, if they work at all, and this type of best technology thinking is one reason they often don't work. Almost any locally grown crop would have more going for it, regardless of Jatropha's yield and general usefulness. That's no reason not to use Jatropha, but it has to be fitted in properly, and once again full local involvement is essential for that to happen. Best Keith __ Do you Yahoo!? Yahoo!

[biofuel] suggestion for a beginner
I m a beginner in biodiesel field. to start with i have used fryed(with beaf) groundnut oil to make methyl ester. To do the performance test on engine i need calorific value of this ester.i have the following doubts 1. will the properties of ester affected due to frying with beaf. i will be gratefull if i get exact calorific value. i have found the cv of ester of unused groundnut oil as 39500kJ/kg regards K.M.

But my advser specializes in organic synthesis. Yes, so you said. Nonetheless, I suggest you start at the beginning rather then with an advanced method: http://journeytoforever.org/biodiesel_make.html#start Best Keith I am a fourth year student from the University of the Philippines and for my thesis my adviser suggested making biodiesel and analysis of its characteristics. We thought of using the procedure from the Philippine Coconut Authority but when my adviser saw the Foolproof Method outlined in Journey to Forever, she said it was a better method. The experiment will be supervised by my thesis advisers; one of them specializes in organic synthesis. The Foolproof Method acid-base process is about the best method available, but it's an advanced method, as I said. It says this right at the top: NOTE: The two-stage biodiesel processes are advanced methods, not for novices -- learn the basics thoroughly first. The single-stage base method is the place to start. Start here. http://journeytoforever.org/biodiesel_aleksnew.html Foolproof biodiesel process: Journey to Forever Here being here: Where do I start? http://journeytoforever.org/biodiesel_make.html#start Have you or your thesis adviser who specializes in organic synthesis made biodiesel before? Keith Addison Journey to Forever michelle manglicmot wrote: I will be trying to make biofuel from coconut oil through the method suggested in journey to forever. Which one? There are several, not all for novices. it was stated there that product will be allowed to stand for 3 weeks. is it possible to cut short this time? Yes, after finishing the wash, try heating the biodiesel to 45 deg C, if it goes cloudy again do it a second time, but it shouldn't go cloudy after the first time - it would mean you should improve your processing. You'll accomplish the same end in little more time without using more energy for heating by letting it stand in the sunshine for a while. But which process are you intending to use? Please give the url. Please note what it says about the stoichometric ratio of methanol to coconut oil here: http://journeytoforever.org/biodiesel_meth.html How much methanol?
