We earlier submitted a report we headlined as "USDOE Hydrogasifies Coal, Recycles Carbon", in which we disclosed "United States Patent 3,988,123 - Gasification of Carbonaceous Solids; October, 1976", the revelation of a technology owned by the US Government, wherein Coal, and other "carbonaceous solids", could be gasified with Steam to produce an hydrogenated "fuel gas or synthesis gas".
Herein, we see that our Department of Energy was about half a century late in recognizing, developing - and then stuffing away into some sort of sealed lockbox, or rat hole - such technology.
We have previously documented that the Steam gasification of Coal, to produce a synthetic "natural" gas, which includes a high percentage of Methane, which as you should by now know has some special potentials, through bi-reforming and tri-reforming technologies, related to the recycling of Carbon Dioxide, has been practiced for a long time, generating vaporous fuels known, among other names, as "Producer Gas" and "Town Gas".
