[Gasification] New Gasification Project

I believe there was a math/typing error on the initial email
140,000 TPY  X  2000 lbs/ton  X  8,000 BTU/#  =  2.24 X 10^12 BTU  (not 10^24)
Therefore 1.56/2.24 should equal about 69.6% conversion efficiency.

 Dear Listers, 

	SASOL has a 45-49% total BTU conversion efficiency from coal to useful products, not just diesel fuel. 

	When one takes the output BTU/input BTU which is 1.56 10^12 Btu/2.24 10^24, I can't see the conversion efficiency at 69%, as there are several zeros missing, or am I missing something?  

 140,000 ton x 2000 lbs x 8000 Btu = 2.24 10^24 Btu of wood
12 million x 130000 Btu = 1.56 10^12 Btu of diesel
	Jet Fuel is a fraction of the total diesel MW fractions typically made in FT processes and unless they go to a total wax product and then hydrocrack it back to jet fuel, as BP/Amoco did in their GTL project in Anchorage, the process gets quite complicated and inefficient. 

	There are catalysts that will produce a 43% diesel MW spectra and limited CO2, CH4, and C5+ fractions, but most are in the 20-30% range, and the rest of the products have to be converted to the diesel MW range. There are some new catalysts that have excellent diesel range conversion efficiency with low cost, long lifetime, and this may be increased by changing the operating mode in the reactor. No one has tried the change in operating mode which to me is quite obvious from the reaction time needed to form the products. This combined with an intrinsic heat removal process makes for a radically different design. 

Sincerely,

Leland T. "Tom" Taylor

Mark,

Kingsley Field is located near Klamath Falls, OR but Southwest Airlines has the fuel contractArt

Isn’t there a USAF base nearby to help them get rid of all of the jet fuel they’ll be making?

140,000 ton x 2000 lbs x 8000 Btu = 2.24 10^24 Btu of wood

12 million x 130000 Btu = 1.56 10^12 Btu of diesel

1.56 / 2.24 = 69%  efficiency

To get an idea of the amount of fiber:

140,000 / 20 ton (triaxle truck) = 7000 loads per year

7000 / 365 = 19 loads a day. Green wood would be more. Not counting the wood needed for the lumber.

But those are baby log trucks compared to Michigan's trucks with pup trailers and 11 axles. No idea how much they can haul in Denver.
