Just wanted to share some interesting results with you guys on my own polymerization testing. This is only the beginning, but found it very informative.

Jason,

Good information. Could you perform another test using Biodiesel blend?

 

FN74
An interesting study that revealed the tip of the iceberg.

Polymerization occurs secondary to oxidation. The WVO you used would have had much higher levels of FFAs and peroxides due to exposure to high heat levels during its original use. Another contributor to oxidation is the water that comes from the material being fried, The period of time it was in use and the surface area, where the oil is in contact with air, is also significant.

The new Canola (Rapeseed) oil was not previously subjected to heat and water thus it would have to go thru the oxidation process before polymerization would occur. 8 hours of moderate heat, in comparison to the temp deep fryers are kept at for very long time periods, and the absence of water may not have been enough to reach critical peroxide levels.

Another point there is evidence that Diesel Fuel additives actually destabalizes VO. That may account for the effect you noted in the stanadyne samples.

Good beginning long way to go before you can reach any conclusions

 

there are a few conclusions that can be reached. If you finish a test, and have no conclusions or results, then the test was not effective. Maybe I should say theory's. But you are right in that one test in one man's kitchen does not constitute law. And this is certainly only the tip of the iceberg. There are almost endless directions I can go with this. I do plan to test different materials, and different additives. I found it most interesting how even only a 10:1 mixture of WVO and #2 completely nuetralized the formation of Polymers, which is one of biggest advantages of Biodiesel besides the visocosity, which still becomes a mute point in cold weather. So I will continue to do some more testing to see if I can get a handle on being able to exactly control polymerization, and not just make educated guesses......

 

There is a lengthy report available on the topic that I can send you by e-mail, if you want it. I have tried to post it here but it is to big.

It makes some specific recommendations on reducing polymerization.

send email addy by PM if you want report.

 

willbd
Report sent let me know if you get it ok

 

Phy,
Got the report.

Thanks,

FN74,
I seem to recall hearing bad things about WVO mixd with #2 + agitation equaled lots of a waxy substance settling out of his mix. But it did not happen with the same WVO mixed with #1.

Try it in a jar, it may have just been the WVO he was getting, never tried it myself.
Just food for thought.

MooseHead,
These guys use bigger words then I will ever dream up playing with my kids. I think "jar" may be substituted with storage mixing device with variable agitation control....Phydeax is some sort of top secret chemical guru and FN74 is the CEO, CFO and what ever other 3 letter abbrev we could think of a company using the proper way to use wvo with dino.

 

Jason's link in the first post is no longer working. Does anyone have a good link for the test and the pics that were also contained in the link?

 

I just tried also and could not receive it either.................WTF

 

Looks like some construction is going on over at Vegistroke.

 

Is it construction there or the changes here?

I wonder if the new format makes the hyper link no longer good?

Also, does this site now seem slower than ever?

 

I didn't use the hyperlink, and it said it was under construction.

 

There have been several bugs with the new VB, which are getting worked as fast as we find them, but it looks like FN's link problems are on that end.
