We have cited the Axis Coal conversion scientists named in this WWII-era patent many times previously.
Ernst Donath, especially, we have identified as being a key figure in Germany's extensive Coal liquefaction industry before and during WWII, who went on to work, after the war, in exile in the US Virgin Islands, perhaps in partnership with his son, to develop even more advanced Coal conversion technologies, all the rights to which were assigned, through the Secretary of the Department of the Interior, home at the time of the US Bureau of Mines, to the United States of America, up into the 1970's.
Mathias Pier is another of the German Coal conversion scientists we have previously identified for you as having developed key technologies for the gasification and liquefaction of Coal prior to the war.
Herein, we see that they pooled their talents, and together devised an even better way, as confirmed by our own United States Government, to convert Coal into "motor fuels".
Comment follows excerpts from the enclosed link to:
"United States Patent 2,339,106 - Production of Motor Fuels
Date: January, 1944
Inventors: Mathias Pier, Heidelberg, and Ernst Donath, Manheim, Germany; vested in the Alien Property Custodian.
The present invention relates to a process for the production of motor fuels.
We have now found that aliphatic hydrocarbon oils, substantially of the middle oil boiling range, can be cracked under such reaction conditions that, though hydrogen is present, it is not consumed, that high pressure is not needed, that the catalyst remains active for remarkably long periods of time, and that gaseous hydrocarbons are formed to a comparatively slight extent only.
As initial materials may be mentioned middle oils ... obtained by the destructive hydrogenation of coals ... .
(Hydrogen is generated within the process, and, consequently, elemental) hydrogen is required merely at the outset of the operation, but nothing is added during the operation; there is no need, therefore, of means for the preparation of hydrogen.
(And, thus, no need for any additional expense to allow "for the preparation of hydrogen".)
The hydrocarbon oils obtained by a single pass through the reaction chamber consist (of) 30 to 45 percent gasoline, the balance being aromatic middle oils.
The resulting gasoline is a non-knocking motor fuel.
The aromatic middle oils may be returned to the reaction chamber or converted into non-knocking motor fuels by any other suitable method, as for example a destructive hydrogenation.
Example:
A paraffinc middle oil obtained by the hydrocarbon synthesis from carbon monoxide and hydrogen is passed over a catalyst consisting of active alumina with 6 percent molybdenum trioxide (under specified conditions, yielding) 16.5 percent of gaseous hydrocarbons, (and the balance consisting of liquids composed of) 44 percent gasoline and 56 percent middle oil.
Claims: (A) process for the production of knock resistant motor fuels from hydrocarbon oils."
---------------
And, such "hydrocarbon oils" from which such "knock resistant motor fuels" can be produced, as Donath and Pier specify earlier in the Disclosure, by "the destructive hydrogenation of coals".
Further, keep in mind that the "knock resistant" Gasoline is actually produced from the "middle oil" that is, initially, co-produced with a lesser-quality Gasoline from a process based on that "destructive hydrogenation of coals"; which we take to mean, as it was defined in earlier of our reports, the Steam-, or Hydro-, gasification of Coal; and, which can be conducted so that all the necessary Hydrogen, needed for the further catalytic condensation of Carbon Monoxide into hydrocarbons, and even the further refining of those hydrocarbons, is generated during that "destructive hydrogenation".
