Pittsburgh 1924 CO2-Free, Nitrogen-Free Coal Syngas

Method of producing gas

In a brief series of recent reports, we've begun to document the use of various metal oxides as Oxygen donors in Coal gasification processes.

The use of such "Oxygen donors" to effect the partial oxidation of Coal, or, as we will demonstrate in other reports to follow, any  Carbon source, is a far more effective way to accomplish the gasification since it  enables the attainment of several important goals.

Since, as we recently reported in:

2011 Efficient Extraction of Flue Gas CO2 | Research & Development; concerning: "United States Patent 7,927, 572 - Purifying Carbon Dioxide and Producing Acid; 2011; Praxair Technology, Inc.; Abstract: Carbon dioxide is purified by processes employing NOx-rich sulfuric acid that can be formed by removal of SO2 from the carbon dioxide (and) wherein said gaseous feed stream of carbon dioxide is formed by combustion"; and:

United States Patent Application: 0060051274

This will, we caution, be an extended and unfortunately cluttered presentation. We are herein making further report of the Carbon Dioxide capture and recycling achievements made by a team of scientists about whom we have previously written, as in:

US Navy and Columbia University Recycle Atmospheric CO2 | Research & Development; which actually centered on:

 

2011 Efficient Extraction of Flue Gas CO2

United States Patent: 7927572

We preface this dispatch, concerning the efficient capture and separation of Carbon Dioxide from the flue gas of industrial processes that combust hydrocarbon fuel, especially Coal, by attempting to address the question of:

When technologies such as disclosed, for example, in our reports of:

Efficient Capture of Atmospheric CO2 | Research & Development; concerning: "United States Patent 7,993,432 - Air Collector ... for Capturing Ambient CO2; 2011; Kilimanjaro Energy, Inc.; Abstract: An apparatus for capture of CO2 from the atmosphere";

 

Shell Oil Maximizes Carbon Use in Coal Gasification

United States Patent: 4969931

No matter how we convert our abundant Coal into more versatile hydrocarbons, no matter how completely we utilize it's carbon content, there will, just as when we combust Coal for power generation, remain behind an inorganic mineral residue.

That residue is most often referred to and known most commonly as "fly ash", which most think of as settling out of exhaust gases, but larger and heavier agglomerations, "slag" and "clinker", are also formed.
