Re: [Biofuel] Ethanol use has Environmental Downsides
Brazilian cane mills are also powered by leftover cane stalks that heat caldrons to generate steam and electric energy, an extra advantage that corn and wheat don't have. Uh... why not? If you are just using the seeds of the corn (which is stupid enough, true), what about the whole rest of the corn plant?

Re: [Biofuel] Ethanol use
Hi Charles There is a patented information about using the zeolites at the top of the reactor , which can be very selective to adsorb and return back pure alcohol see google search using free patent site. Then you can recover the catalyst using solar energy to remove water.In the case of ethanol , the higher temperature , I am not sure that higher can fovour the reaction.Can any one have the experience to give more informatiion? With kind regars to all biofuel members yours truelyPannirselvam P.V2006/8/21, Charles List [EMAIL PROTECTED] :Hi allIt's slowly turning to spring down here in the southern hemisphere, and a young man's thoughts turn to what he's going to get up to inthose long summer evenings. Me, I think only of biofuel! I am havinggood progress and results with methanol but my long term plan is tobe completely self- sufficient and ferment my own ethanol to use in my reaction. I will first buy some denatured ethanol to practice on,and I have read what is on the JtF web-site and realise I will needto really dewater my oil, use more ethanol than methanol etc. I wouldlike to know, however, if I can increase the temperature of the reaction mixture to cut down the time taken for the reaction asethanol boils at 78C rather than 65C, and if there are any otherhints/ tips people can give through their experience of this reaction.Thanks Charles List This email was sent using Telecom SchoolZone.www.schoolzone.net.nz This email has been scanned for viruses by Telecom SchoolZone,but is not guaranteed to be virus-free.--___ Biofuel mailing listBiofuel@sustainablelists.orghttp://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever:http://journeytoforever.org/biofuel.htmlSearch the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/-- Grupo de Pesquisa em Engenharia de Custos e Processos DEQ – Departamento de Engenharia QuímicaCT – Centro de Tecnologia / UFRN, Lagoa Nova – Natal/RNCampus Universitário.

Re: [Biofuel] Ethanol use
Hello Ken, Charles et al. Ethanol can be somewhat tricky to deal with when it comes to producing biodiesel. The glycerine drop is related to the amount of ethyl esters that you have created during the process. This is suggesting that you will need a certain qty of ethyl esters produced in order to have a spontaneous glycerol drop. To make sure that you have a sufficient amount, the ethanol stochiometric surplus should be at least 75% or rather 100%. The stochiometric relationships are much more important than increasing of the reaction temperature, say 5 or 10 degrees. But also note that the ethanol inserted has to be anhydrous. Best of luck to you !

RE: [biofuel] ethanol use
Hi Craig Hi Keith FirstlyThank you Keith for the very informative info you pointed out on ethanol use in a gasoline motor. You're most welcome, glad it helped. Secondly..The amount of info I have managed to get by scounging a bit deeper. I have learnt a yard full in such a short time. At present I am building another 25 litre BD proccessor for myself and brother in law. His Isuzu diesel van has the 2.5 litre engine powering it. My proccessor is a 2 tank type, How does that work? but waiting for a promised pump to complete the little monster(my wife's affectionate name for it) She reakons it looks allien with the pipes and funny goodiescoming out of it. :-) Didn't think of that, but so does ours. Damn... now I'll have to go and paint a smiley on it. Best wishes Keith Great Craig Emmerick For those who missed out on the info..try these.

Re: [biofuel] ethanol use
Hi Craig Hi chaps and lasses Why can't I use methalated spirits in my petrol engine? :-) Ah, the good old days... That'll need a translation for some of the list members. Petrol = gasoline, a spark-ignition engine. Is there any reason other than it been more expensive than petrol? When I looked at what makes up meths. I found out it contains about 90% ethanol and about 5% methanol. It varies, depending on where you are, various denaturants are used, including MEK, for instance. What's the colorant? Probably very little of it anyway. Could I get away with using meths, could anyone answer this for me please. Probably, yes, if the 5% methanol's all that's added. Methanol is corrosive, and so is ethanol, though less so, and much is made of that sometimes, mostly by the parties you'd expect to object. For more info, see for instance: Intensive Field Trial of Ethanol/Petrol Blend in Vehicles http://journeytoforever.org/biofuel_library.html#ethanoltrial A complete report covering all of the applications of ethanol in gasoline, in new and used engines: ERDC Project No 2511 Intensive Field Trial of Ethanol/Petrol Blend in Vehicles.
