Todd, I hope that you're interested in pursuing this discussion, but
I understood that most feedstocks contain palmitic and stearic acid
components (rapeseed, sunflower, seseme, mustard, groundnut),so which
one did you use that contained none of these acid components?

Paddy,
A bit curious as to why you would perceive there to be no
interest in pursuing biofuels discussion. That is, after all,
what this list is dedicated towards.
As you know, your understanding is correct. Most if not all
vegetable oils have some palmitic and stearic fatty acid content.

run though a cracking unit to get the right carbon chain length. So that
the diesel would gel at a lower temperature. What would be involved in
building a unit that would handle 50 to 100 gallons at a time?
Hello Phillip.
AFAIK the pumps are all mechanically driven, though some have electronic
control over injection timings etc. Not sure of the pressure that the pump
operates at but the opening pressure on the injectors in my 80 series Diesel
landcruiser are 17,652 - 18633 kPa Thus the pump
when are we going to exhaust fossil fuels, can any one tell me how
scientifically this is estimated.

no one really knows, and odds are they will never really be exhausted. It
will just become much more expensive to obtain them. 30-40 years maybe for
oil..

Dear Shaji,
This is estimated in several ways, depending on who is doing
the estimates. The most usual value is Known Oil Reserves divided
by Yearly Oil Production (R/P), which theoretically should give
you the number of years that you can continue to produce oil.
In this case it is no
So that'd be about 260 PSI? What's the pressure of the cumbustion in a
diesel?
Does the pump have to withstand the cumbustion pressure, or is there a
check valve somewhere?
Thanks!

Just a note once again that soybeans may not the best choice, and certainly
are not the only one -
Sunflower, canola/rapeseed, mustard, nut trees, palm, coconut, jatropha,

inedible, some are edible, some are trees (nice!)

What is the current price of surplus soybean oil. I have made BD from WVO
and from soybean oil, and the soy oil gives a much cleaner (more
valuable???) glycerin layer at the bottom. I understand that glycerin is
very hard to purify and get it to where it is an economically valuable
co-product.
There is no back pressure on the pump. The injector needle closes it is like a
one way valve. To work out the pressure in the combustion chamber you could
multiply the capacity of the cylinder by the compression ratio, assuming the
air entering is at one atmosphere. If it is forced

What I meant was *moving* the cellulose supply-line from farm-based
