Shell Oil Recycles CO2

United States Patent: 4640766 
 
The, we would contend deliberately, vague title of the United States Patent we enclose herein doesn't even begin to convey the import of the technology disclosed. And, the, again we would contend deliberate, heavy use of abbreviated generic chemical formulae does little to clear things up.
 
Only when you get to the "Preferred Embodiments" section, do the inventors, and our United States Patent Office, take a stab at revealing the true import.
 

California 1929 Coal Liquefaction

Patent US1730997
 
We thought that the US Coal-to-Liquid conversion Patents from the 1930's we've posted so far, nearly all of them issued to German, Austrian and Japanese scientists, were pretty nifty items - until we stumbled across the gem, almost like the fabled diamond discovered in a Coal seam, we enclose herein.
 

Big Oil CO2 to Methanol Photosynthesis

United States Patent: 4427508
 
We've documented in our reports that some scattered groups of scientists around the world, in Singapore, Israel and Switzerland, for instance; and, even some in the United States, at our Sandia, Los Alamos and Brookhaven National Laboratories, have not only been developing ways in which Carbon Dioxide can be profitably recycled into valuable hydrocarbons, but, basing those methods of CO2 conversion on the use of freely-available environmental, renewable energy.
 
We've also documented, and will document further, that some private corporations, including oil producing companies and oil industry service companies, and United States defense contractors, such as United Technologies and Hamilton Standard, have been developing similar technologies; though the technologies  arising from the DOD research center mostly on the unpalatable use of nuclear power to drive the CO2 collection and conversion.
 

Pittsburgh 1933 Syngas from Coal & Steam

Process for the production of hydrogen
 
In our dispatch of 5/28/10, we documented how, in 1943, during WWII, a United States Patent had been awarded for Coal conversion technology - "Patent 2,337,551 - Producing Gas Mixtures for Synthetic Purposes" - to inventors resident in Japanese-occupied China, and was then vested in the Custodian of Alien Property.
 
As it happens, one of the two named inventors in that patent, prior to the onset of war, had actually shown us, in the United States, how to make an hydrogenated synthesis gas out of Coal, by using Steam.
 
And, he did so pretty close to home.
 

DOW Chemical Liquefies Coal in 1978

United States Patent: 4102775
 
We have submitted multiple reports documenting the development and practice of Coal hydrogenation and liquefaction technologies by the old Union Carbide Corporation, at a pilot plant in South Charleston, WV.
 
Much as other companies who developed similar innovative technology for the full employment of Coal, such as Pittsburgh's Gulf Oil, who was swallowed up by Chevron, were taken over by other companies not as interested in publicly promoting the full use of Coal; or, as with Exxon and Mobil, whose documented coincident interests in Coal conversion might have helped to inspire their merger, Union Carbide met a similar fate.
 
In early 2001, they were absorbed into, and became a wholly-owned subsidiary of, Dow Chemical.
