Re: [Biofuel] RE: jelly and jellybiofuel
Wauw !! Somebody - and not JUST somebody - on this forum writing in real Dutch. Very good Keith. You're not kidding? You're very kind, but I don't think it's real Dutch. It's been a long time, it's a horrible mixture of bad Dutch and even worse Afrikaans. I can remember just enough to see the mistakes without knowing how to correct them. If I can't remember a Dutch word then the Cantonese word comes to mind instead! Can you imagine.

Re: [Biofuel] RE: jelly
so my question is, can I also make BD from the FFA's with the single base reaction ? No. But you can run the recovered FFAs in an single tank, IDI system. The viscosity is low enough. You just won't be able to run any saturated FFAs (palm, coconut, hydrogenated and animal fat), as they solidify at higher temps, the same as do their parent stocks. If the recovered FFAs are liquid at 50*-70*F you can run them straight or blended with petroleum or biodiesel. Todd Swearingen Pieter Koole wrote: Hi Todd, Thanks for your answer.

Re: [Biofuel] RE: jelly and jellybiofuel
Isn't jelly solid ethanol Sterno fuel? Or is Sterno made with methanol? It's hard to imagine that there's any energy advantage to jellied fuels over woody plants for cooking purposes, I know that many third world areas have extreme shortages of cooking fuels or firewood, but it seems like that's a distribution problem, more than a real shortage. I know there's been a great deal of debate about the energy return of ethanol production here. But no matter what the numbers, it seems clear that when you don't need an energy dense liquid fuel for engines, the most efficient (and easily embraced) supply would involve fast growing woody plants. My impression is that burning biomass provided the best overall return of solar energy. Am I missing the UN's intention here?? Or is this another boondoggle?

Re: [Biofuel] RE: jelly
Pieter, The broken soap is nothing more than free fatty acids, with a glycerol/alcohol/water/residual-acid layer beneath it and (if using potassium hydroxide as the original catalyst) solid fertilizer beneath that. FFAs in their pure form are only slightly more viscous (hadly noticeable) than biodiesel and can be run in an indirect injection diesel as is or heated and run through a veg-oil converted system. Or, you can convert them to biodiesel with acid/base processing. Todd Swearingen Pieter Koole wrote: And what can you do with the broken soap ?

Derick, Still, treat a small sample with concentrated sufuric or phosphoric acid and observe. Todd Swearingen DERICK GIORCHINO wrote: Thanks for the response.

In a smaller beaker, dissolve 1 ml of the cooled oil in 10 ml of pure isopropyl alcohol. Warm the beaker gently by standing it in some hot water, stir until all the oil dissolves in the alcohol and turns clear. Add 2 drops of phenolphthalein solution. Using a graduated syringe, add 0.1% lye solution drop by drop to the oil-alcohol-phenolphthalein solution, stirring all the time, until the solution starts to turn pink and stays that way for 10 seconds. -- From: Biodiesel from waste oil http://journeytoforever.org/biodiesel_make.html#biodwvo See also: More about lye How much lye to use?
