<div><span class="ecxApple-tab-span" style="white-space:pre;"> </span>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. </div>
<div><span class="ecxApple-tab-span" style="white-space:pre;"> </span>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. </div>

<br>
1.56 / 2.24 = 69% efficiency<br>
<br>
To get an idea of the amount of fiber:<br>
140,000 / 20 ton (triaxle truck) = 7000 loads per year<br>
7000 / 365 = 19 loads a day. Green wood would be more. Not counting the wood needed for the lumber.<br>
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.<br>
