Hi Ross
Hi all,
Keith,the quality is not a question,according to my
NIR the BD is 99.2% esters - the foolproof method -
acid stage and 2 alkaline stages with glycerin removal
between ,
Good going!
Then it really seems a pity to bother about the colour.
By the way, where do you get the 60% FFA
If the coloured particles (maybe with so high percent of FFA, this oil has
been used for many cicles of heating or a strong treatment, and probably it
has a high decomposition ratio) are quite small, bentonite has not capacity
to recover from the media. The carbon is better for this purposes.
Hi All,
I apologize to you guys,it is my mistake,the stuff is
not any oil,but residues from refining oils in the
process called degumming,where the oils are treated
with water solution of lye and the resulting soaps are
treated with acid to recover the FFA`s.Generally it is

problem to esterify it, but the BD is the same dark

bentonite - no result.Has anyone any idea how to
lighten the BD?

Hello
A little bit of coloured sustances, can make a very high coloured solution,
so if the reaction goes correctly, it must not be a problem. Try to bleach
it with activated charcoal, heating close to boiling point and adding then.
The problem is that you will need to filter it quite well to remove
Hi all,

with fuel and the people asking me What is that black
sh.t you are producing?
After methanol recovery if acid was added it would split the soaps into ffa
and salts. Then washing should remove the salts and lower the acidity with
very little if any soap in the wash water. It might reduce washing to 1
cycle per a batch. And would be safer to dispose of because no soap just
into BD. I hope to add it to the BD I use to heat my house.
Best of
luck,

becomes solvent in the glycerol that drops or the excess alcohol that

However a question - first acid stage (1.0cc 97%

Keith others- I am a bit fuzzy on what happens to FFA in the production of

explain what happens to the FFA. Is this converted to methyl ester or is there
another reaction? Do fatty acids have another use?

From Dave Elliott (Dave UK):
Acid catalysis
FFA can probably be acid catalysed. I've not tried this, but the basic recipe
has been looked at by an analytical chemist who thinks it should work.
Acid catalysis is a water tolerant process. Use 10% methanol mixed
with 2% to 3%
