I tried to make the stuff from cotton without the Nitrogen. I did the
pyrolysis and the sulfonation for half the time. I guess I was too
impatient. I tested it with WVO with 12% FFA. After

Hi Chris
The way I see it, this new catalyst isn't environment friendly at all.
So much energy is needed to pyrolyse sugar at 400 degrees centigrade
for
15 hours. On top of that, you need to heat it at 150 degrees with 200mL
of concentrated sulfuric acid

I'm not trying to be negative. We need more Mr.Lins. I just wish that with his
knowledge and training he could remain focused on research
Looking in Prof Lin's publications, you can see a few references that
appear to be about the catalyst.
If you are like me and were wondering about the chemistry behind it,
then perhaps check out this one:

It says on the second article that the catalyst is made of calcium and
sand, not sugar and sulfuric acid.

Thank you for the information John it is helpfull now to get reading.

If the catalyst is reusable, but only 20 times, what happens then? Can the
catalyst be recycled?
The details are vague but it seems that this is intentional as it seems Mr.
Lin and his colleagues and especially the University

It says the particles are made of sand and calcium. The actual catalysts are
attached to the surface of the particle and the active catalyst compound is not
described (except to call them mixed oxides). I say catalysts because they
mention having both acid and base catalysts on the same

Hello Steve,
Yea it a bummer to see our think tanks beg, but the bottom line is if
they start producing the catalyst for sale, chances are we can buy it,
not so different than going to your local chemical supply and buying KOH
