In this dispatch we submit yet another decades-old United States Patent, held by yet another then-major oil company, that confirms the reality of Coal liquefaction technology, not by describing the ways in which Coal can be transformed into liquid fuel, but, as with other, similar, oil industry patents we've recently brought to your attention, such as Esso/Exxon's US Patent 35114394, by establishing a technique to recycle or renew the catalysts employed for the liquefaction of Coal.

In a previous dispatch, we made reference to a recent United States Patent application for recycling Carbon Dioxide, into Methanol and Dimethyl Ether, made by two University of Southern California scientists, Nobel Winner George Olah and, his colleague, Surya Prakash.
A review of our records revealed that we had, in fact, not yet transmitted information concerning that patent application, and we herein attempt correction of the oversight.

United States Patent: 5213908
We earlier documented that NASA owns technology which enables, and would enable, our US astronauts to make both Oxygen, as is practiced now aboard the International Space Station, and rocket propellant, as they intend to do on Mars, from Carbon Dioxide.
Herein, we report that the US Government also owns the rights to a technology that would enable us to use Carbon Dioxide to generate electricity.
And, as we point out in comments following, even though this technology was, no doubt, developed for our Space Program, it does have more mundane terrestrial applications.

As in a few of our previous dispatches, we herein document the reality of Coal-to-Liquid Fuel technology, not by reporting how Coal liquids are made, but by demonstrating that some considerable effort has been put into the development of technology to further refine Coal liquids, once they are synthesized.

We have lately been reporting on the broad utility of Methane, i.e.: how it can be directly converted into liquid hydrocarbon fuels; how it can be reacted, or "tri-reformed", with Carbon Dioxide to synthesize higher hydrocarbons; and, how it can enhance the productivity of indirect Coal conversion technologies, to create improved synthesis gas suitable for catalysis into liquid hydrocarbons.
Herein, a report of research, financed by the US Government's Office of Coal Research, we believe to have been published in 1970, confirms that the versatile Methane can itself, as we have earlier documented, be manufactured via the steam gasification of Coal.
