obviously your professor is not fully informed.
Virgin oil and for that matter the waste oil has long carbon chains- 18 or
so but on esterification these chains are broken down to 11 - 13, very
similar to that in diesel. Due to about 11% oxygenates avialble in
biodiesel( which is
Dear Rajendra
I found it interesting that you mention on esterification that the chain length
is broken from C18 or more down to a chain length of C11 - C13.
Can such a difference be due to the variety of oil that is selected? The reason

Hi Keith,
In answer to your question:
Lets start with a litre of oil.
Ours has a density of 910.9 grams/litre so a Free
Fatty Acid content of 5% on a weight basis means that
5% of that 910.9 grams is FFA
So one litre of oil with a FFA content of 5% (weight
basis) contains 45.55 gms of FFA
I just found out that dessicants like silica gel only work in humid
air (because of their high surface area, low vapor pressure pores).
Osmosis would work to selectively separate water from ethanol. The
process uses a polyvinyl alcohol (PVA) membrane developed in Japan.

This is all in the archives, several times perhaps. You have several
steps to go still before you find a good way of removing the 5% of

What questions? Perhaps I was away from my computer. Anyways there
is alot of information on that website about using cellulose as a

There seems to have been a flurry of postings lately (maybe just
a couple misguided individuals, I don't know :-)) about biodiesel
from ethanol (rather than methanol). This used to be one of my
favorite subjects until I gave up in disgust. Still, out of nostalgia,
I tried again this weekend. You
Here is something else that really ticks me off: coal liquefaction,
making gasoline out of coal using the most environmentally
destructive means, is getting far more attention than this.

It's an interesting read. Particularly important because starchy

by throwing away plant fiber, we're wasting 99 percent of the

I wonder if there was a homebrew way of making
