Ok. A couple weeks ago I made a batch of Biodiesel. I don't know what went wrong. Hangover I guess. Now what do I do with it. No jokes please. Thanks David

David,
The Biodiesel could be re-reacted again to see if you can get better conversion.

There's a great article here that discusses reprocessing:

Reprocessing was also discussed in great detail here as well:

Ive made a few bad batches. I discovered the best way to start over is to crash everything out with water. take a sample and add water till it seperates.

David,

not joking, welcome to the 'oops' club..

please understand..oops to some mean one thing and to other it might mean something else..

please describe your process.
HPT results
titration ( KOH or NaOH)
processor temperature
base caustic?

mix time
pump?
process tank size? are you using a 5 gpm pump on a 200gallon tank?

and yes I have made most if not all the mistakes you thinking about making..i have the best oil finished shed floor in 3 states..or more..please not light a match..my floor is water proof not flame proof..Smile

Dkenny I've made great biodiesel from my system before. I really don't remember what I did with this reaction that failed. I think it was a bad calculation of carry over meth from acid reaction. I don't think I added enough methanol to the transesterification. So I got this less unreacted bio.

In that case a reprocess will solve the issue.

It was an oops that made me realize how castor oil could be polymerized. Sometimes oops is good! (If I could just remember how I did that!)
