I'm in Australia but you didn't seem to be getting much response from the UK so I chipped in. As keith suggested a search of the archives is always a good starting point.

Hello All, I have been letting my BD sit for a couple weeks to precipitate the soap/salts out of the BD. After filtering (even though it was clear as refined apple juice) the ph tested at about 5.5. I have tested this procedure by washing a sample of the BD and the wash water is clear. Does this mean that just letting the BD sit long enough will do the same thing as a bubble wash?

[biofuel] ethanol fuel
Hi, I'm a new member to this group and if anyone could answer my questions I would be very grateful.' 1. What is the best recipe for converting potatoes to ethanol. Specifically, I have a recipe that says to just boil the potatoes and use only the liquid for fermentation. Is that the best way, or should I mash up the potatoes and try to convert all the starch? 2. Does anyone have a good recipe for converting corn to ethanol? 3. I built a valved reflux still and I need to know what is the best packing to use in the column. Right now, I'm using glass marbles with a 1/2 diameter. I have heard of using Raschig rings. Are they more efficient? How about steel wool? 4. I would like to convert my 2 cycle lawnmower to run on ethanol fuel. Any suggestions on engine conversion? Thanx. Yahoo!

[biofuel] Pool Filters for WVO
Has anybody out there ever used a swimming pool or spa filter to clean used fryer oil? I've been looking at the fryer oil filtration systems that restaurants use, and they seem awfully expensive for what you get (like $1500-1800 USD for a new one with only a 30-liter capacity!) I can get a brand-new pool filter system, based on diatomaceous earth (so you could also add an FFA-removing filter powder), with a throughput of 30 gal per minute (!!) for under $500. You might not want to get the oil real hot (the guy said 120 F would be fine), but it seems like it might be a great system. Any thoughts? Yahoo! Groups Sponsor -~--> Tiny Wireless Camera under $80!

Re: [biofuel] Simple glycerin refining technique-Biodiesel
OK, I hesitate to do this as I am nearly overwhelmed at this point and I see no immediate use personally BUT: If anyone is interested in forming an "Internet based" research team to explore the possibility that a simple process can be developed to refine "glycerin waste" from biodiesel production let me know. I don't think I have the time to assemble and manage such a team now but I can tell someone else how to begin the process and help along the way. I have done this for many years via email mail and conference phone as well as face to face meeting and am currently attempting to do so using only email. At this point I believe that though I don't have the time to do so myself I can help anyone with basic management skills to do it. Contact me if you are interested in either being on such a team or (especially) acting as "moderator/manager" of such a team. Dana __ Do You Yahoo!? Send FREE video emails in Yahoo!

Re: [biofuel] Correction to Recipe

I sent the recipe to Livio direct, and then posted the correction to the group -- duhh! Anyway, the recipe is pretty obvious. I told Livio if he couldn't get any methanol to mix in, the 1% water in the ethanol would have to be removed with quicklime or mol sieve, and the oil would have to be very clean and dry, well-refined. 280-320 ml ethanol, and 7g NaOH or 10g KOH, per liter of oil. Actually I arrived at the 7g NaOH empirically (it's the molar equivalent of 10g KOH, and it works!) -- the 10g KOH is standard in the literature, and seems to be the right amount empirically as well.
