United States Patent: 6572829

Herein, we submit a sequence of documents which, taken in total, might represent a productive route for the utilization of a pollutant that can be created during the Steam-gasification of Coal, itself undertaken to generate a synthesis gas suitable for subsequent catalytic processing into hydrocarbons.

First, we remind you of: FMC Corporation Recovers Sulfur from Coal Syngas | Research & Development; which makes report of a technique for the extraction of Sulfur from a process for  the:"gasification of carbonaceous solids (i.e., Coal) with steam to give product gas containing carbon monoxide and hydrogen" suitable for catalytic condensation into various hydrocarbons, and wherein the Coal gasification can result in the co-production of Sulfur Oxides.

United States Patent Application: 0020072109

This will be an overly-long dispatch, and we apologize for it's extent. But, there is a lot of ground to cover.

We have, over the past several years, presented many reports documenting the genuine potentials which exist for the productive, and profitable, recycling of  Carbon Dioxide: whether naturally-occurring, such as the vast quantities of it emitted by volcanoes; or, human-derived, such as the CO2 generated in the processes of cement-making.

We have focused, in those reports, primarily on the direct, industrial recycling and usage of Carbon Dioxide, as seen more recently in:

ConocoPhillips Recycles Even More CO2 | Research & Development; which includes the details of: "United States Patent 7,273,893 - Process for Converting Carbon Dioxide to Oxygenates; 2007; Assignee: ConocoPhillips Company, Houston; Abstract: A catalyst and process for converting ...  a feed comprising carbon dioxide and hydrogen into methanol and dimethyl ether"; and, in:

United States Patent: 4673473

Carbon Dioxide, reclaimed from practically any source, can be productively recycled in the synthesis and manufacture of both gaseous and liquid hydrocarbon fuels, and, of valuable industrial chemicals.

We've previously cited the two, what we presume to be former, Texaco scientists named as inventors of the United States Patent we enclose herein, attesting to that fact, as can be seen in:

Texaco Recycles CO2 to Methanol & Methane | Research & Development; wherein is reported: "United States Patent 4,523,981 - Means and Method for Reducing Carbon Dioxide to Provide a Product; 1985;

Chinese coal producer reaps huge profits from CTL project

The cost of Coal liquefaction, done to provide substitutes for all the fuels and other products we now derive from petroleum, has been raised as an objection to the implementation of Coal liquefaction technology.

We have in previous reports documented cost analyses, which demonstrate that Coal conversion can, indeed, be very cost-competitive with petroleum; and, maybe even more than competitive, especially if we consider the indirect loss of wealth to our nation, and to our domestic economy, incurred by both the purchase of foreign petroleum and the expenditures we, as a nation, must make to defend both those overseas sources of oil and the transportation routes that bring the oil from them, to us.

United States Patent: 4025575

We have many times made reference to, and reported on, ExxonMobil's "MTG"(r), methanol-to-gasoline, technology, wherein the Methanol is posited to be made from Coal.

The latest, what we take to be key, piece of that Coal conversion technology was, we think, encapsulated in a United States Patent we earlier made report of, as in:

Mobil Oil Coal to Methanol to Gasoline | Research & Development; which concerned:

"United States Patent 4,447,310 - Production of Distillates through Methanol to Gasoline; 1984; Assignee: Mobil Oil Corporation; Abstract: A process for producing a wide slate of fuel products from coal is provided by integrating a methanol-to-gasoline conversion process with coal liquefaction and coal gasification."
