I ran 4 tanks of it. It went down around 3mpg (from memory).

That's good enough for me, thanks man. B30 it is!

SPR? Refresh my memory, I'm feeling stupid. What are you asking?

Small Personal Refinery. For cracking WMO into diesel.

geordi is in agreement with ADM in his findings that animal fat enhances fuel economy over straight Vegi stock.
Would Snake Oil be as good or better?
A Plan to get more Snake Oil:
1) Farm Grow the Snakes in the Southwest Dessert and feed them mice fattened up on Midwestern Corn or Cotton seed.
2) Open a Restaurant Chain called "Rattlers" serving Mesquite cooked Snake Steaks.
3) Cook the Snake Stakes over grills that have grease recovery that renders all the fat out of the Snake Stakes.
4) Place the Snake Stakes in a centrifuge for a few seconds to get out all the grease.
5) Serve the yummy Snake Stakes.
5) Use geordi's Biodiesel process to make Bio from the Snake Oil/Waste Vegi Oil Blend

I can't wait to eat Mesquite Grilled Snake Stakes and fuel up my CRD on Bio made from Snake Oil Stock

Good God I wish that I could have Bio in Central Florida.

Fuel is from 2.58 to 2.70.

I don't get it.

More BRITISH THERMAL UNITS per Gallon with animal fat in the blend. ADM wanted to do it too like geordi did but the Federal Government did not want Henny Penny or Porky Pig in the fuel tank. Snake Oil reference is a finger in the eye to the Government Idiots who stopped ADM for using animal fat in their blend to get more BTUs per gallon.

Oh.
Today I added a gallon of used canola to my special summer blend of D2. even at just 2% veg, I can tell a difference in the clatter.

No, I never really got started on that. My graduate program has been keeping me pretty busy, and the results I had last summer with straight WVO were less than impressive. That is why I got stuck with a plugged filter in New Jersey.

Maybe in the future, I'm not ruling anything out. It will still be interesting to build a small column and see what kind of separation I can get with some heat.

Just to clarify some terminology....

Fatty Acid Methyl Ester --> The desired product of the transesterification. This is your biodiesel. It doesn't come in with the feedstock. Those are fatty acid glycerol esters.

Cracking --> In the context of refinery operations, process in a specialized reactor utilizing a fluidized bed of catalyst flowing through pipes where oil is adsorbed upon it and heated to very high temperatures in order to break long carbon chains into shorter ones.

Way back when I was a coop, Ashland had a pilot process for converting motor oil into a useful feedstock for refining. It was basically steam distilled...they literal passed superheated steam (probably about 500 degrees F) through a vat and it would carry clean oil vapors over with it. They couldn't just feed the waste motor oil in and crack it directly because the residual metals left behind. Those metals would quickly foul their expensive catalyst. It can't be filtered out, so distillation of the waste motor oil is the only way to get around it. The tarry stuff left behind is probably mixed in asphalt compositions.

Based on what I just read in the post, it seems that you guys are actually planning to distill the waste motor oil. If that is the case, you may want to consider getting a quality vacuum pump and a nitrogen tank. Put the system under vacuum and then sparge nitrogen through the distillation pot...doesn't take much, just want a gentle bubbling. This will help liberate and carry the distillate over. Use of the nitrogen also makes the process more safe since it inerts the system and helps prevent fire.

Warp, that would be sweet! You could market it as Joe's Snake Oil Biodiesel... the advertising possibilities are limitless!

Not planning...done. And no, I don't "distill" the motor oil, because it has too few middle distillates. And no, a catalyst is not necessary for cracking, they merely lower the cracking temp, and, or target specific length chains. Nearly all my product is thermally cracked into middle length hydrocarbons of approximately 12-16 carbons(estimated by viscosity). A small amount of light and middle ends comes out through distillation as I am heating the retort up at around 200*C, but it is very negligible. The main event happens between 420*C and 480*C.

Fluidized bed catalyzers are very nice and all but way overly complicated for what I do. Besides the catalyst would be rapidly poisoned by all the metals in the oil, and the de-additiveizing process is much too expensive and complicated.

The cracked product can be further distilled once it has been cracked, but I don't go through that final polishing because the raw stream is pretty clean and my vehicles love it.

Sorry to offend you. I will no longer offer clarifications. I wasn't suggesting you go out and build a fluid catalytic cracker. And really, I was just trying to be helpful.

I suspect the metals already in the oil help catalyze the process which is why you guys seem to get by with relatively low temperatures. The homolytic bond dissociation energy for a carbon-carbon bond is pretty high. I checked out the link above. It's pretty interesting stuff. You might get a lighter colored product if you perform the process under a nitrogen blanket so that there is less oxygen around...of course, having a little oxygen around my help the process. It might be interesting to submit some of your product and samples for analysis by HPLC and/or mass spec and see if corroborates the viscosity data...you could have already done this. It's just that with the temperature dependence and the fact that the viscosity-molecular weight dependence follows an exponential relationship.

No, the apology should mine. I was just being stupid in the middle of the night when I couldn't sleep. If you read the intro section at OTD, the catalytic contribution of the oil additive metals is already addressed. The problem with depending on those additives for targeting any kind of precise polymer production, is that every batch of oil has different amounts and kinds of additives.The cracking going on at the temps which I am operating at is actually probably heterolytic in nature, but it is very hard to say. In this kind of open system with highly variable parameters, there are probably thousands of chemical reactions going on all at once. Your experienced input would actually be very valuable to our community at OTD.
