United States Patent: 4101416

As with many of our earlier reports, it is seen herein that, not only can primary and long-known Coal tars, as can be generated in Coke ovens, be hydrogenated via long-established petroleum refining techniques, processes that are well-known in that industry, but, once the Coal tars are thus hydrogenated, they can be made to serve as the agents of dissolution, liquefaction and hydrogenation for more Coal.

As confirmed by our United States Government, both by their issuance, and by their sponsorship, of:

Information Bridge: DOE Scientific and Technical Information - - Document #6701984

We recently made report, now published by the West Virginia Coal Association as: 1915 CO2 Recycling | Research & Development | News; of a technology wherein Carbon Monoxide could be produced, on an industrial basis, by reacting Carbon Dioxide with hot Coal.

In the course of that report, we also included information concerning: "United States Patent: H000243 ; United States Patent H243 - Hydrocarbons from Carbon Monoxide and Water;1987; Assignee: The United States of America", wherein it was demonstrated by a group of USDOE scientists, at the Brookhaven, NY, National Laboratory, that a low-Hydrogen content synthesis gas, as might be obtained by reacting hot Coal with Carbon Dioxide, could be reacted with, or supplemented by, Steam, plain old H2O; and, it's ratio of Hydrogen to Carbon thereby adjusted, to make the synthesis gas more amenable for catalytic condensation into desired hydrocarbons.

United States Patent: 3971636

Herein, we again cite the Coal conversion expertise of Pittsburgh's former Gulf Oil Corporation.

In this case, they combined a couple of Coal gasification techniques to improve the production of Carbon Monoxide and Hydrogen, i.e., hydrocarbon synthesis gas, from Coal; and, they did so in a way which illustrates, in confirmation of some of our previous reports, that Carbon Dioxide can be utilized, and recycled, in Coal gasification processes.

By way of introduction, note that they are, herein, first deliberately making Carbon Dioxide, from Coal, for further chemical reduction, with more hot Coal, into Carbon Monoxide.

United States Patent: 7500997

We believe that we've previously cited for you at least one of the two inventors, both scientists at the University of California, Riverside, named in this recent US Patent for Coal conversion technology.

We call their work again to your attention since, in this already-issued patent, and in a later patent application filed by UC, Riverside, which we will make report of in coming days, several key facts about the conversion of Coal into more versatile hydrocarbons, which we have, from other credible sources, previously documented, are reconfirmed.
