We have earlier cited the Coal conversion achievements of both the German scientists named in this, yet another pre-WWII Coal liquefaction technology developed by German scientists; and another one in which the rights to the technology were assigned to a New Jersey corporation.
Ernst Donath, specifically, we remind you without linking to earlier of our reports, was a key figure in Germany's development of Coal-derived liquid fuel technology, which the Axis powers utilized to a great extent during the war. He was, subsequent to WWII, as we have previously documented, consigned to some sort of cushy exile in the US Virgin Islands, where he, and/or, possibly, his son, continued to develop Coal conversion technologies, in service to the US Department of the Interior, the original parent agency of the US Bureau of Mines.
We have also reported the independent Carbon conversion achievements of Heidelberg scientist Mathias Pier; and, we see herein that the two teamed up to develop a procedure for more completely hydrogenating carbonaceous liquids derived from Coal, and converting those Coal liquids into hydrocarbon fuel raw materials.
Comment follows brief excerpts from the link to, and attached file of:
"United States Patent 1,938,087 - Separation of Hydrogen
Date: December, 1933
Inventors: Mathias Pier and Ernst Donath, Germany
Assignee: Standard-I.G. Company, New Jersey
Abstract: This invention relates to improvements in the separation of hydrogen which expression also comprises gases rich in hydrogen from gaseous mixtures ... .
We have found that hydrogen or gases rich in hydrogen can frequently be separated from ... industrial gases such as water gas ... (and) waste gases from destructive hydrogenation processes in a very advantageous manner and without troublesome chemical conversions by washing the gaseous mixture at elevated temperature and increased pressure with a hydrocarbon liquid ... .
(First, such "destructive hydrogenation processes" which can produce generous quantities of Hydrogen, would include, as we've separately and variously documented, the Steam-gasification of Coal. But, the kicker is to follow, as immediately below.)
Among hydrocarbon liquids (are included) the products of the destructive hydrogenation of coal ... or products obtained by the distillation of the same.
(In other words, plain old Coke oven tars, as would be "obtained by distillation of" Coal, could qualify as the "hydrocarbon liquids" which would be combined with "waste gases from destructive" Steam-gasification of Coal, to from more-fully hydrogenated hydrocarbon liquids.)
It is particularly advantageous ... to employ the waste gases containing hydrogen and gaseous hydrocarbons obtained by the destructive hydrogenation itself as the gas mixture from which the hydrogen is to be separated.
(Note, again: Pier and Donath are specifying that the gases obtained from the Steam-gasification of Coal are to be combined with the tars obtained from that Steam-gasification, to effect the production of fully hydrogenated hydrocarbon liquids.)
Claims: A process for the separation of a gas rich in hydrogen from a gaseous mixture ... which comprises washing the said mixture ... with a hydrocarbon liquid."
---------------
To rephrase and summarize:
In a coking process wherein Steam is added to the mix of Oxygen-deficient gases with which Coal is being coked, both Coal tars and a Hydrogen-enriched gas are produced.
Those products can be combined, in a "washing" process, as disclosed herein by Pier and Donath, to extract Hydrogen from the product gas and transfer it into the somewhat Hydrogen-deficient Coal-derived "hydrocarbon liquid".
We submit, although Pier and Donath go on to explain how the Hydrogen can then be extracted from the Coal liquids, presumably for use in other applications, that the more-fully hydrogenated Coal liquids could then be further processed, in something more akin to a modern petroleum refinery, and made thereby to produce direct substitutes for standard petroleum products.
In any case, the accomplished German Coal conversion scientists, Donath and Pier, as confirmed by the United States Government, herein reaffirm a fact we have previously documented:
We can manufacture fully-hydrogenated hydrocarbon liquids, direct replacements for anything we now derive from natural petroleum, from Coal; and, we don't really need anything but Coal, and Water, to accomplish the transmutation.
