Today's link is the Propel Fuels Blog. Unlike most alternative fuel blogs, it's still active and relevant with original content.

Sorry, it's working for me. It goes to the Triangle Biofuels Blog and is an article that uses the same NREL document as it's source reference as the Oasis Biofuels Post. I like the Oasis Biofuels article a little better as it seems more direct and to the point.

Both articles used this as a reference:

I've been doing a bit of research lately and ran across this document

Saturated monoglyceride effects on low-temperature performance of biodiesel blends

This is some of the most recent research published on biodiesel. To paraphrase the conclusion:
Saturated MonoGlycerides are bad bad bad in winter. They have a greater impact, ounce for ounce on cloud point than saturated FAME. When the content of Saturated MonoGlycerides is between 0.01% and 0.03% there can be unexpected filter plugging above the cloud point temperature. And finally, when Saturated Monoglycerides crystalyze, they form an unstable "alpha" crystal structure. when heated, this "alpha" crystal structure changes to a less soluble, stable "Beta" crystal structure and plug up fuel filters.

Making biodiesel using Enzymes is one of the newest areas of biodiesel research

The sustainable biodiesel alliance has a short pdf file called:

The SBA Good Book of Biodiesel


It contains blending charts for soy biodiesel, canola biodiesel, WVO biodiesel, and animal fat biodiesel. These charts give you an approximate cloud point for various blends of these fuels.

Today's link is to a blog post on Blue Planet Green Living about Green World Biofuels. That would be a company run by TDI_Steve making biodiesel processors.

I believe the post "titrating accurately" is not exactly correct. The time for a complete neutralization reaction is not mentioned. I reacted potassium hydroxide dissolved in anhydrous isopropanol with stearic acid. After 20 minutes it was still warm indicating an exothermic reaction was still occurring. Titrating the ffa content of vegetable oil has a time and reaction temperature consideration that goes with it. I'm just saying the description of how to do it "accurately" is a little bit wrong. When I titrate the vegetable oil I wait at least 30 seconds before considering that I've added enough titrating fluid. Thanks

Today's link is to one of my websites. This is Tim c cook's system for treating really nasty oil.

Terrific ideas people come up with. Thanks Tim, and thanks Rick for bringing these to our attention.

The Collaborative Biodiesel Project is a student-led initiative at Appalachian State University. The purpose of the project is to create a closed loop biodiesel processing facility that provides for its own energy needs, and recycles its waste products.

Today's link is a little bit off topic. We've had a couple of threads on the topic in the past, and this is a good article.
