Yes, almost sadly, we submit even more documentation of the fact that, for more than half a century, both the petroleum industry and our own United States Government have known that Coal can be hydrogenated, and thus converted into more versatile hydrocarbons, through fairly straightforward interactions with Steam.
We know these submissions are redundant, but we do try to avoid repetition. The fact that there are so many official US documents like this stashed away just serves to confirm how real, and how highly-developed, the science for hydrogenating Coal, and converting it on a practical basis into liquid and gaseous hydrocarbon fuels, really is.
It also serves to confirm that such knowledge of viable and practical Coal conversion technology has, for whatever reason, been left to lie fallow; squirreled away so as to remain unused and unknown by the people who have, over the past decades, most deserved to have the tools of Coal conversion placed into their hands:
