United States Patent: 4684756


Last November, as available via: Exxon Lubricating Oil from CoalTL Wax | Research & Development | News; we sent you report of:United States Patent: 5290426 - High Porosity ... Catalyst and its Use; 1994; Assignee: Exxon Research and Engineering; which, it's title aside, actually disclosed a process technology that could "produce high yields (of liquid hydrocarbons) from a synthetic Fischer-Tropsch wax".

Such "synthetic Fischer-Tropsch wax", we remind you, is a buildup of semi-solid hydrocarbons that can accumulate on the surfaces of catalysts used to condense synthesis gas, derived from, among other sources, Coal, into liquid hydrocarbons.

United States Patent Application: 0090205254


Via separate dispatch today, we are sending along report of:United States Patent: 4002658; wherein Ford Motor Company reveals how we can synthesize Methane from relatively high-Sulfur, and, thus, presumably, lower-cost Coal.

Further, as in just one example out of many we've so far provided you, we see in: Illinois Recycles CO2 to Methane | Research & Development | News; that we can also synthesize Methane from reclaimed Carbon Dioxide.

United States Patent: 4523986


We yet again cite the former Texaco Corporation, now a component of Chevron, in demonstration of the fact that any Hydrogen, which might be required for the hydrogenation of Coal's content of Carbon in order to synthesize more versatile hydrocarbons, can be generated as an integral function of the Coal conversion process itself.

That fact is made clear in our excerpts, with comment appended, from:

United States Patent: 4002658


We have many times documented the fact that Methane can be synthesized from Coal, as well as from, via the Sabatier process, Carbon Dioxide.

We have also, in the course of our reportage, occasionally noted that Sulfur, as is, unfortunately, often found in Coal, can be detrimental to catalysts employed to convert synthesis gas, derived via the hydro-gasification of Coal, into Methane and other hydrocarbon products.


Actually, it was an Illinois scientist in the employ of a Swedish company, with some headquarters offices in the Netherlands, who informs us herein that, in a much later version of the 1912 Nobel-winning Sabatier process, Carbon Dioxide can be converted into Methane.

First, the named assignee for the rights to this Carbon Dioxide recycling technology is the "SKF Trading Company"; and, even though they are listed as being headquartered in Amsterdam, they actually originated in Sweden, and are a fairly significant multi-national corporation.
