Continuous Production of Palm Methyl Esters, D. Darnoko1 and Munir Cheryan*, University of Illinois, Department of Food Science and Human Nutrition, Agricultural Bioprocess Laboratory, Urbana, Illinois 61801 A system for continuous transesterification of palm oil was developed using a continuous stirred-tank reactor (CSTR) and pumps for continuous delivery of oil and catalyst and for continuous removal of product. Potassium hydroxide was used as the catalyst, the methanol-to-oil molar ratio was 6:1, and reaction temperature was 60¡C. The yield of methyl esters increased from 58.8% of theoretical yield at a residence time of 40 min to 97.3% at a residence time of 60 min. However, higher residence times decreased the production rate. During long-term continuous operation, the CSTR displayed steady state conditions in terms of product profile and methyl ester concentration. This process has good potential in the manufacture of biodiesel Paper no. J9575 in JAOCS 77, 1269-1272 (December 2000).

[biofuel] Biodiesel from Palm Oil
Hanns Wetzel in PNG wrote: "Does anyone know what proportions of ethanol and potassium hydroxide per volume of palm oil have to be used to produce biodiesel from palm oil, or does anyone know of a site on the web where this process is described like on the URL mentioned above. I am looking for info on how this could be done in Papua New Guinea, a large scale producer of palm oil." I'm ttying to work out more or less the same thing here in the Philippines, only for coconut oil. The procedure is simple in principle but rather laborious in practice. You start with the composition of the oil: what triglycerides are present and in what proportions. That allows you to calculate the weight of glycerol per unit weight of oil. Glycerin is a trihydroxy alcohol and ethanol and methanol are both monohydroxy alcohols, so each molecule of glycerin has to be replaced in the transesterified product with three molecules of either ethanol or methanol. That, and the respective molecular weights of glycerol and the alcohol you're using for biodiesel will give you the stoichiometric amount of (m)ethanol required. That is not the final answer, but it is a starting point for experimentation on small batches on the benchtop. You can work out the exact proportions at small scale, with purchased anhydrous alcohol, while working out a way to get larger amounts cheap. Somewhere in my files is something on that topic, too, if I can just find it... Somewhere in the rat's next that passes for my file system I should have something on palm oil and palm kernel oil compositions, which I ran into while researching coconut oil. Naturally I can't put my hand on it now, but I suspect you already have that info, living in a major producing area. My scheme-in-progress still centers on methanol, which I hope to produce locally by destructive distallation of agricultural waste. One tiny problem is I can't find any info anywhere on how much of the stuff I might expect from the materials available here. Before petro-methanol became too cheap to compete with, methanol sold in the West was produced by distilling hardwood chips in a closed retort, so there's plenty of info on yields from temperate zone hardwoods. Too bad we don't see those in our outposts of civilization. I don't think I'm up to building a retort, plus all the apparatus for separating tars and purifying the methanol, just to get numbers...
