Patent US4152244
In an earlier dispatch, posted April 4 on the West Virginia Coal Association's R&D site, and titled "Britain Liquefies Coal with Coal Tar", we reported that a US Patent, Number 4521291, had been awarded to British inventors for, as we have, from other sources, documented to be feasible, using primary and long-known Coal tars and oils, which can be extracted from Coal in a fairly direct way, as agents of hydrogenation and liquefaction for additional raw Coal.
Our United States Patent Office, as documented herein, further confirms the validity of such technology, in their award of:
"Manufacture of Hydrocarbon Oils by Hydrocracking Coal - United States Patent 4,152,244
Date: May, 1979
Inventors: Ludwig Raichle and Walter Kroenig, Germany
Abstract: Production of hydrocarbon oils by hydrocracking of finely ground coal ... in a mixture of middle and heavy oil produced by the process ... . The middle and heavy oil used for the slurry is in part middle and heavy oil derived directly from (the process). Suitable starting materials are ... coal, lignite or peat. The dried coal is slurried with a distillate oil taken from the process ... . (The products) are separated in distillation columns into gasoline, middle oil and heavy oil."
----------
The full patent disclosure is replete, of course, with technical descriptions, illustrations and examples.
They all serve to prove the point, that, starting with "finely ground coal", and using "oil derived" from "the process" itself, we can make "gasoline".
