Esso 1972 Coal Liquefaction with Coal Oil

 
Herein, we submit further documentation of a few points we've been attempting to establish.
 
First, of course, is the fact, that, not only can our abundant Coal be efficiently converted into Gasoline, but, Big Oil and our own US Government have known that to be true for many decades.
 
Our US Government, at least as it is embodied in the Patent Office, has known that we can make Gasoline out of Coal since a time well before we, the American People, started being economically victimized by foreign OPEC powers and profit-centered Big Oil corporations.
 
Second, primary and long-known Coal oils, as we have many times reported, can be utilized as agents of liquefaction and hydrogenation for raw Coal. 
 
Brief comment follows excerpts from the enclosed link to, and attached file of, yet another United States Patent attesting to those facts:
 
"United States Patent 3,692,662 - Coal Liquefaction at Staged Temperatures
 
Date: September, 1972
 
Inventor: Edward Wilson, et. al., Texas
 
Assignee: Esso Research and Engineering Company
 
Abstract: In the solvent liquefaction of slurried caking-type coal solids ... the formation of unconvertible coal residues is reduced by first forming a substantially complete dispersion of the coal in the solvent before exposing the coal to depolymerizing temperatures.
 
Background: This invention relates to the conversion of coal solids to liquids, and more particularly, to the liquefaction and hydrogenation ... of coal slurried in liquid vehicles.
 
In processes designed to produce liquid hydrocarbons from coal, oils derived from coal are typically used to slurry (and) carry the coal into ... reactors where ... liquefaction ... occurs."
----------
 
First, did anyone, in US Coal Country, especially back in 1972, know that "coal ... liquefaction ... occurs", "typically", anywhere?
 
In any case, and in sum, Big Oil and the US Government confirmed, as herein, very nearly four decades ago, that, by then, there were already multiple "processes designed to produce liquid hydrocarbons from coal", and, that, "oils derived from coal" could serve as efficient "vehicles" to convey raw Coal into "reactors where ... liquefaction ... occurs".
