I did find this interesting though: "... * Acrolein can be formed from the breakdown of certain pollutants found in outdoor air, from burning tobacco, or from burning gasoline. (1) * Airborne exposure to acrolein may occur from breathing contaminated air, from smoking tobacco or proximity to someone who is smoking, or from being near automobiles or oil or coal power plants. In several large cities, acrolein has been measured at 9 parts per billion (ppb). (1) * Occupational exposure to acrolein could occur in industries that use acrolein to make other chemicals. (1) * Small amounts of acrolein may be found in some foods, such as fried foods, cooking oils, and roasted coffee. (1) * Acrolein has not been detected in drinking water, and is not commonly found in surface water. (1)....." Tabacco, cooking oils and coffee, interesting! EPA link

Look's like we had another knee jerk reaction without proper investigation and research. When I was a kid we called it "jumping to conclusions" and we made fun of those who did.

Here is another recent post from one who jumped on the research band wagon. His remarks are on a study that was written using the term WVO Methyl Esters. His point is good that it's possible it caused confusion cause WVO Methyl Esters is NOT WVO. Quote:

Smithfield Hams to become a methanol source for biodiesel plant
Recently there appeared in a SE Virginia news source an item stating that Smithfield Corporation is planning to replace some of the worst of their hog waste settling ponds (the ones which usually overflow every time a hurricane or noreaster comes through, which is often) with a system for recovering the methane from the waste and converting it to methanol, which they then plan to sell to a northern Virginia biodiesel plant which makes fuel for boaters. I don't know any further details.

Remember, the glycerine is what is removed (replaced) from the SVO/WVO to make BD, so if the -whatever- percent of glycerine that is left in the BD that is unreacted or not removed is an issue, then even more so the 100% of glycerine that is in WVO/SVO. Another way, their statement means little for SVO/WVO use except to say that if the little glycerine that is left in partially reacted BD is an Acrolein hazard or issue, then all the more the oil that has ALL of it's glycerine content. But..., we actually need to do the research to determine the amounts (volume) and concentration of Acrolein in combusted SVO/WVO. The BD studies will mean little to us, except to point out that if combusted BD is an Acrolein hazard from the little glycerine that may be left over, then all the more the problem with SVO/WVO that has 100% of its glycerine content. If we actually get this research, then we might be able to come up with an oilseed, algae, etc. that can minimize this output?

SVO and WVO is the base stock used to make BD from - the Glycerine is separated from the SVO AND WVO to MAKE BD, so how do you get the idea that SVO contains no Glycerine?

Once the reactants form glycerin from "some" of the components in SVO it then seperates and is easly removed. The remaining material is what is called bio-diesel. Again. Glycerin is NOT in SVO/WVO. It only forms AFTER reactions from *the alcohol and acid. *or some other way that breaks some of the molecular bonds within the oil.

I guess since I am getting quoted over here, I should speak up and clarify any confusion. As I stated before, there should be very little free glycerin in the waste oil. I will qualify here, as I later realized I should have qualified there, that there may be a very minute amount of free glycerin from triglyceride molecules from which all three fatty acids have broken off during the abuse of high-temperature cooking. Even then, the waste oil should still be at least 95% tri-, di-, and monoglycerides and 3-4% fatty acids. The remaining percentage would be comprised of randomly polymerized particles from the heat, moisture, salts, etc., etc.
There is a big difference between glycerine and glycerides and I think that is where the confusion is coming in. Glycerides have the fatty acids attached to a glycerol backbone, where glycerine has no fatty acids. Now what happens in the combustion chamber is where the whole question gets a little sticky. Maybe at some point in the combustion mechanism there is a time during which free glycerin exists in the combustion chamber. But, at that time there would also be countless numbers of free radicals running around under high temperature and pressure conditions, so it is sort of a guessing game to try to say what side-reactions are taking place. Until I see a scientifically-valid, peer-reviewed study specifically on acrolein emmissions, I am going to sit on the fence on this issue. In the meantime, I will happily continue to spew vile emmissions, ruin the IP, and coke the injectors (I will try to keep the rings of the uncoked variety-there has to be limits to the destruction one is willing to cause) of my veggie-burning SDL.

In my first WVO conversion, I used the factory fuel system to supply the WVO. I fashioned a marine tank in the trunk to supply biodiesel. I had read that new fuel line withstands biodiesel, so I plumbed the purge fuel with regular fuel line. This summer I was running B100 exclusively to start and purge, and as a result I was plugging the factory fuel filters about every other week. The material seemed to be fine black particles in the primary filter, and black paste in the secondary. I had been running B20 previously since last November when I got the car running, and thought my filter pluggings were behind me.
My conclusion: Biodiesel EATS fuel lines. None of my new lines are leaking, but they are noticeably larger around, and obviously the insides are dissolving. The biodiesel I use is Blue Sun, nothing homemade (yet!). My second conversion, working on presently, I am using the factory tank and steel lines to run my biodiesel, and all flexibles lines are Viton save the cigar hose. My WVO will be the add-on fuel system, just like everyone elses. I seem to have to learn lessons the hard way.
