Re: [Biofuel] Cuphea Oil seed
Hi Tony It should be okay for biodiesel, it's been raising quite a lot of enthusiasm in the industry in the US, but maybe that just means it's better than soy. It's supposed to be similar to palm oil and coconut oil (high caprylic and lauric acid content), yet the cloud point is low, -9 to -10 deg C. I didn't find an Iodine Value for it though. HTH - best Keith Hello List, Has anyone used cuphea for bio-fuel? If yes, what were the results? Any additional information is appreciated.

Re: [Biofuel] Cuphea Oil seed
Hello all. The Cuphea oil is similar to coconut oil with an iodine value of approx 17. This confirms its high content of saturated fatty acids, should as biodiesel create a nice cetane number. The catch could be the biodiesel final boiling point which should turn out scientifically lower that 350oC. Good or bad ? It would be nice to judge that from a report on the properties of Cuphea oil biodiesel.

Re: [Biofuel] Cuphea Oil seed
Has anyone ever used Moringa seed oil for biodiesel? Please see link for reference: http://www.treesforlife.org/our-work/our-initiatives/moringa We have found Moringa tolerates the desert heat well, grows very quickly, will flower in desert climes and handles saline water. Main problem is deer and rodents love it. It has to be grown in a cage if you have any wildlife in your area or it will disappear. The leaves also have a remarkable flavor. I am cultivating a small patch of jatropha (3 years). It grows well. But, it will not flower due to the dry desert heat. I plan to use it for it's medicinal value.

Re: [Biofuel] Cuphea Oil seed
Hello Jan Hello all. The Cuphea oil is similar to coconut oil with an iodine value of approx 17.

The catch could be the biodiesel final boiling point which should turn out scientifically lower that 350oC. Good or bad ? It would be nice to judge that from a report on the properties of Cuphea oil biodiesel. The other catch is the cloud point, I'm not sure I believe the report I quoted that it's -9 to -10 deg C, especially not as you confirm the low IV of 17. More likely it starts to gel as soon as the weather gets cool, same as palm oil, coconut oil, lard, etc. If it does, then one wonders why it's being promoted in the US as a substitute for palm oil. Hot tip: invest all your bucks and your grandmother's life savings in US companies making pour-point depressants. Ref. Iodine Values http://journeytoforever.org/biodiesel_yield.html#iodine Further catch is that it's an awkward crop to process. The seeds are tiny, and they tend to shatter. Cuphea isn't really domesticated yet, it's more like a wild weed. Actually the biodiesel is just a sideshow, the main attraction is the caprylic and lauric acid, valuable industrial feedstocks, cloud point irrelevant. Industry enthusiasm, hm. In the US that means either B20 or B5, maybe a low cloud point doesn't matter if you're going to mix it with 80% or 95% petrodiesel.

Re: [Biofuel] Ethyl esters biodiesel - Lee - was (no subject)
Hello Lee Did you have any results yet with heads and tails tests? Best Keith Keith: Thanks for responding. I do a second distillation using calcium chloride and then 3A molecular sieve to dry the alcohol. So far I have been using 50% lard mixed with 50% soybean oil (both used) . I am in the process of eliminating the lard and using used soybean oil with a titration of 2 grams NaOH per liter. I use KOH at the U. of Idaho's recommended amount of 1.3 Kg per 100 liters of oil. I have been using 1/3 purchased methanol mixed with 2/3 self produced ethanol and using 20% alcohol by volume in the reaction. The ethanol is 99% pure. Lee Hello Lee I have been making biodiesel using ethanol for about a year. Methanol is $500 a barrel in Hawaii. I'm having some difficulty with partial conversions with substantial vegetable oil remaining dissolved in the ethyl esters demonstrable by the methanol test. I have been using 99% alcohol I make from sugarcane that I grow. How do you get such a high proof? Distilling it only gives about 95.6%. Are you using zeolyte to dry it? What kind of oil are you using, and is it new or used? If used, what's the titration? Are you using KOH or NaOH? I am currently using all distillation fractions including the light and heavy alcohol portions. Any thoughts on whether it would be better to use only the ethanol fraction in order to encourage more complete conversions? I'd suggest using only the ethanol fraction in a test batch, then including the heads and tails in a second test batch, and comparing the results, via the methanol test and the wash test.

Re: [Biofuel] Aftermath of Copenhagen
Hi Darryl www.10n10.ca is looking good, well done. I'll upload a link and description at JtF. For our part, our carbon footprint isn't too bad, probably better than most. We haven't bought any petro for more than six years, we grow almost all our own food, we compost everything (THE best way to capture carbon). We live in a 100-year-old wooden farmhouse, which is GOOD, according to a recent feature article in the Japanese press, because wood is a renewable resource, it said, and it also said that most Japanese houses are wooden, and they last an average of 30 years before they're replaced. That might be so in the cities and suburbs, but most of the rural population lives in these 100-year-old houses, same as ours. They were built in a huge post-Meiji rural restoration scheme. Unlike our house though, most of them have been extensively restored and modernised, so they're warm and comfortable. The current debate in our house is whether it's warmer in the kitchen or the fridge. Or colder rather, warmer isn't the right term at all. So, we earn a plus because our house has lasted 3.3 times longer than it should have, and a big extra plus because of something the feature article didn't say, which is what happens to the wood when an old house is demolished and replaced: it gets landfilled. :-( The article also didn't say that, while the post-Meiji rural houses were built with local wood, Japan imports most of its wood these days, preying on other people's forests, not necessarily sustainably. High carbon costs (maybe we get a few extra points by default). Here's a toss-up: do you think the very footprint-unfriendly fact that, in spite of the wood stove in the kitchen (used only on really cold evenings because of a high hassle factor), we have no choice but to use kerosene space heaters in the living rooms (unless you'd consider hypothermia a choice), is offset by the brownie-points we score for not using, never having used, and having no intention of ever using the electrically-heated toilet seat in the loo (which is outside and is even colder than the kitchen/fridge)? Heated toilet seats are de rigueur in Japan. Is that the case in Canada too? Sweden? No offset, eh? The kero's worse? 'Tis the work of the devil that biodiesel won't travel up a wick. As for 10n10, we'll try, but no promises. All best Keith I guess it will surprise no one that I am skeptical to cynical of the value of this bit of spin. I suppose some will want to credit Obama with putting lipstick on a pig for the agreement reached at Copenhagen. That the agreement is non-binding, and the targets are essentially set for higher emissions than under Kyoto, despite the evidence amassed since that accord, strikes me as a Faustian deal. Because the agreement is non-binding, it's just a screen to hide behind while we play out a climate change version of the tragedy of the commons.

The agreement emerged as the primary achievement of the United Nations Climate Change Conference in Copenhagen. The non-binding agreement calls for deep cuts in global emissions of greenhouse gases so as to hold the increase in global temperature below 2°C, and it calls for industrialized countries to determine their economy-wide emissions targets for 2020 and submit them to the United Nations by the end of January. A number of developing countries, including the major emerging economies, also agreed to list their voluntary pledges to reduce emissions by the end of January and agreed to communicate their efforts to limit greenhouse gas emissions every two years. The Copenhagen Accord also calls for international support of a comprehensive adaptation program and of mitigation efforts by developing countries. The accord commits developed countries to provide new and additional resources approaching $30 billion for the 2010-2012 time period, balanced between adaptation and mitigation. Developed countries also committed to a goal of mobilizing $100 billion per year by 2020 to address the needs of developing countries. The accord establishes a new Copenhagen Green Climate Fund to coordinate the distribution of a significant portion of this funding. According to the secretariat of the U.N.
