Jan, I am the wrong person to answer those questions. I think they are using gasification and then F-T, but that is just a guess on my part. I live in the White Mountains of New Hampshire, and we are exploring using low grade wood (woodchips) as the feedstock for ethanol production. We are leaning towards gasification. Does anyone in the group have any comments on that technology?

The composition of this reminds very much of that of soy bean oil. But it takes a lot of distilling and fractionizing to get this fatty acid fraction clean enough. Wood is more suitable for ethanol production I think.

If my memory is correct, they're getting about 60 or so gallons per ton. A major oil company has bought an interest in the company.

If so, alot of stuff could be made into biodiesel -- grass, weeds, cardboard, etc... Thermo catalytic cracking is the only thing I can think of that could do this. Unless they have some fancy microbes that can digest lignin and give oil? I also remember that in WWII germany was trying to distill gasoline substitutes from pine trees -- I thought this was more like turpentine though, derived more from the sap than the wood? I'm not an expert on this by any means, but perhaps someone else remembers exactly what they were doing.
