Batch in that T's at 11. .10 mult. Pump running to keep things mixed. Temp 155F
Will follow up with results after 2 hrs, then 4 hrs

T 6 after 2 hrs

T 3.5 after 4 hrs, so Im going to let it run traditional temp, no mix until tomorrow. Hopefully end up around 1.5 or so.

hooknline,

glad you tried this..
my results were about the same?? it didn't work in 1 hr..

to be fair..
1. I didn't neutralize the processor first..I didn't even check..
2. I didn't neutralize the methanol/acid input line either..might be a issue.

this is helping to narrow down possible problems.

I flushed everything with the water as discussed. After 3 flushings, it was very slightly caustic. 1ml of acid solution to neutralize. Same with my injection lines and tank. Neutralizing with acid is the next test after this batch.
I just got home from work, so Im going to finish this beer and go see what the final T is.

T is still 4...not sure whats going on. Oil was extremely dry. I remixed everything, and Im going to let it sit at 130F for a few hours and see what happens. Probably move to base reguardless.
Seems that the mixing impaired the lowest T possible, coupled with using the .10 mult. .15 or .12 might be needed with HTAE just because of the mixing. That will be the next test aling with netralizing the entire batch

-thats been my experience, the mixing for some reason results in a higher ending T. It should also be noted that the tests for htae where done on small samples, this doesn't mean it will work exactly the same on a larger scale. I have found with the htae that I have done, what you have after 3 hrs is all your going to get! Your T4 is most likely the result of caustic residue, it takes very little caustic to neutralize the acid. I guess one to simply add more acid to off set this, but then you create more water when the acid is neutralized in the base process. Tom

Im thinking along the same lines Tom. I going to neutralize this whole batch using meuriatic acid at a rate of 1ml/L of liquid. Hopefully that has better results on the next testing batch. Also, Im going to try .12 mult for the HTAE, and see where that gets me.

Well Ill be a monkeys uncle. T never got below 3.5, so I went on to base processing. Just pulled a sample after 2 hrs mixing...get this.. 82% yield of total voume in the reactor. Leads to 54 gallons of bio...OUT OF 52 GALLONS OIL!
Now, it hasnt passed 3/27. Seperation was clear, and complete in 3 minutes on the sample. So I know its close. Im going to let it run for another 1/2 hour, settle overnight, and do the 2nd base stage in the am after draining....crazy stuff~!

Hook
-I also notice that T is slightly higher after htae, but it does not translate into reduced yield, I'm not sure why, but if you where processing t3 wvo (no ae), the yield woud not be that high. Tom

T3 yield without AE would be about 92-94%. So Ill take 103% before reprocessing any day. especially considering that I started with T11.
So this begs the question, is it from the HTAE? I know heat is a catalyst all on its own. Thats the basis for the supercritical experiment, no outside catalyst needed.
Now, to try to reproduce the results consistently.

Hook and Tom,
Theoretically AE should result in higher yield. Since there is no Glycerol to drop off of a FFA. The higher the FFA% the higher the yield (if it's not lost in draining).
If 100% of the oil were converted to bio there would be an increase in volume of ~4.5%.

I single base T3 oil and get around 96% yield regularly.
Your T3.5 is more like T~1.75 acounting for the sulfuric contribution in the ending T. Combined with the reduced amount of glycerol your yield seams understandable to me. You gotta love AE.

You guys are making me want to AE some T3 oil. I just can't justify the extra energy input. Maybe I'll stumble accross some bad stuff?

-Another great expanation by you are you a chemist? Thanks for the info Tom

Thanks Tom,
Only in the bio shed. Ceramic and natural stone construction is my trade.

99% yield after 2 reprocesses. I want to push it as far as possible for my Ford 6.0

Oh great a block head giving chemistry advice!

Too bad your not closer I have job for you on my front entrance! I would like it done for nothing and yesterday would would be great.... Hey we're all friends here right?

Jon

And I need an electrician Jon. yesterday would be cool, I dont want to pay for labor or materials, but want to upgrade my service and run a 200 amp to the barn. So, when you coming down to FL????

OH ya, no problem.... I'll meet ya there!
200A! are you putting in an electric smelter or starting a gro-op?
Jon

MIL suite...I dont want to ever have to deal with her again if I can help it.

LOL
Sounds like an invitation to come hunt big Canadian White tails to me. If you've got the room and board, count me in.

Hook,
Congrats on the yield. Turning otherwise junk oil into high quality fuel just has to make you feel good.
