Hydrogenation liquefaction of coal employing zinc catalysts
We have previously submitted a number of reports detailing technologies for Coal liquefaction that are based on the use of Zinc Chloride, or other Zinc Halides, to help effect the conversion of Coal into hydrocarbon liquids and gasses.
Such technology was developed intensively, as we've documented, by Consolidation Coal Company scientists prior to, and even after, Consol's acquisition by Conoco.
Again as we have documented, such Zinc Halide technology is now being employed by the oil industry for the "cracking" of heavy crude oil and oil refinery residues.
As it happens, that Consol-developed and US-Patented Coal liquefaction technology, now held hostage in the hands of Big Oil, was first developed, with the support of our tax money, by the US Bureau of Mines.

"United States Patent 2,606,142 - Liquefaction of Coal Employing Zinc Catalysts
Date: August, 1952
Inventors: Henry Storch, Pittsburgh, PA, et. al.
Assignee: The United States of America
Abstract: This invention relates to the liquefaction of coal and its conversion products to obtain liquid products, by means of hydrogenation in the presence of catalysts.
In accordance with the present invention, finely divided zinc alloys ... are employed as catalysts to effect in a positive manner the extent of coal liquefaction.
(The) satisfactory yield in percent of liquefaction of coal and also the effectiveness of our process's catalysts (compared to other processes) stand out distinctly (in illustrations provided).
(The) term 'coal' is intended to include ... all types ... of coal.
The term "pasting liquid" (in which the raw Coal is slurried) will be understood to include various liquids, more particularly oil from liquid products from coal hydrogenation (and) coal carbonization...
Claims: A process for producing liquid products by the hydrogenation of coal ... in the presence of a catalyst comprising a finely divided alloy of zinc with antimony ... (and) thereby producing a high order of percentage of coal liquefaction..."
----------
We the People at one time owned this technology for "producing a high order of ... coal liquefaction".
Based on our earlier reports of Consol's, and subsequently Conoco's, further development of the technology, which Conoco also, it seems, intends applying to petroleum refinery residues, is there any chance we'll be receiving some royalties from its employment?
It's employment in petroleum refining, that is - since no one seems intent on applying it as it was originally intended, as herein by our own US Government, to be applied, i.e., for the liquefaction of Coal.
