O.k so i have been working on some biomass fuels.  But converting used cooking oil to diesel fuel is quite easy.  I was very happy with the outcomes.  For the full documentation on the experiment go over to the private sector.

Finding immersion heating element for thermal cracking waste vegetable oil seems to be very challenging.  Also working with this has been a chore.  Because of the temperature it is difficult to get to the temperature efficiently and keep the chamber sealed.  All rubbers, plastics melt or burn off.  Quite challenging.  Especially when your working on a home experimenters wages.  LOL I'll post all my work from here on out on here.

O.k gas oil is the workings of this project.  We want to make gas oil.


So how do you make gas oil?

Well it's made with standard biomass techniques.

first off this experiment consisted of a 55 gallon steel drum.
a turkey fryer.  
50 feet of copper tubing
a steel barrel with a removable top
various brass reducers and compression fittings.
a 0-30psi pressure gauge.



first off we fitted a sealed steel drum with a reducer in the 3/4" bung hole.  Fitted a tee to that and attached a pressure gauge to the top of the tee.  
Second we attached a compression fitting to the tee and compression fitted a 3/8" copper tube 50' long to that and ran it outside of our work area to a drum filled with water outside.  About 38 feet of copper was actually inside of the barrel of water.  The end of the copper was routed outside of the barrel of water and into a 5 gallon container.
third we put 3 gallons of used cooking oil, the water and fries no decantation was done or filtering to the wvo before pouring it into the sealed steel drum on the turkey fryer burner *note the turkey fryer was reinforced with welded steel legs*.
Sealed the 2" bung back into the barrel and began to heat the barrel.  
First the water came out and began pouring into the container.  (it's the liquid that comes off at the lowest temperature)
After 20 minutes more the oil inside begins to reach the 550 degrees needed to burn the oil.  This "burning" is actually the oil turning to a vapor this is great it's what we want.  We now began to see the pressure gauge coming up.  After 2 batches of doing this we realized the best pressure for this setup was 5 psi when the gas oil seemed to be pouring out the end of the 3/8" copper tubing into the container.  
Only about 80 percent of the fluid we put in came out as gas oil.  
After taking several samples labeling them and putting them in our deep freezer which was at -10 degrees Fahrenheit.
We seen that the water at the bottom of the sample froze but the gas oil on top did not.
The gas oil is very aromatic and tends to burn the eyes like a diesel additive from power service that boosts cetane.  
We added nothing to the gas oil after distillation.  
Liptis testing showed great results from the gas oil vs fuel oil.  
A knock test showed smoother and quicker starting.
ASTM results showed a 55 cetane value vs a 41-45 from our local fuel suppliers.  Sulfur was .002 vs .2 from local suppliers.  
Lubricity results were about the same.  Viscosity test showed only .01 percent better lubricity than diesel.  But this could differ according to the type of WVO.  Ours was Pure canola and the second batch was blended corn,cottonseed oil.  

I believe if we re ran the gas oil through the distillation process we would have ended up with a equivalent to gasoline.  Because we would have removed even more hydrocarbons from the molecule we currently have.  
Further testing will tell.  


day two:
I have no way to test the little bit of gas that I believe i have made but it burns quickly I have compared burn rates of the gas oil vs diesel and so i decided to do the same here with regular unleaded to this new product.  Both seem to burn just as quickly and clean.  I will run them in a gasoline engine side by side and listen to the difference see if there are deposits left on the valves, exhause, piston and head after running it for several hours.  I'll document everything when i get time but i'm doing this out of pocket for the time being.  If i had more vegetable oil and money I would produce more results.  I'm broke for now.  Back to work.

by the way the above sample is a final test product.  It's what ran out of the end of the copper tubing and into my container.  The chamber pressure was at 5psi gas temperatures exceeding 725 degress (vapor temp) but the oil temp was a mere 550 - 600.  Easy to obtain with fire on the barrel.  Our new distiller now uses two 4500 watt run dry water heater elements rtv glued and bolted into a new barrel.  We power this 9kw heater with our 10k genset running on wvo.  This worked much quicker because with a 4500 watt element the wvo turns to vapor instantly when it touches it without having to heat the whole barrel of oil.  

The water seems to be saturated with some chemical (further testing needed) but it burns very poorly but does seem to burn with a propane torch lighting it.  Potent stuff.

The end product pictured at the top is still with me today.  It lights easily with a match and comparing it to fuel oil #2 gives us mirrored results.  We will be looking for people to help with the design of a larger unit to break down not only vegetable oil but a mix of bio and fossil fuel based items into gas oil.  

back to basics
I am looking back into this project finally after much time in between simply because no one is pursuing this at all for some reason.

I will be building an explosion proof chamber this time in order to fill with trash and have a nice exhaust product.  

I feel that this is the wisest choice these days with tons of trash and no where to put it.  At least it can be condensed and complete waste product can be reused.  I will post video of production and more.


  

  Thanks for sharing out so much of your precious opinions, see you after heated discussion: I feel that

learning to many. Thank you!
