Carbon monoxide manufacture

 

We submit herein yet another example of technology developed prior to WWII, wherein reclaimed Carbon Dioxide can be reacted with hot Coal, and recycled thereby into Carbon Monoxide.

Of special interest might be the inventor's projected source of the Carbon Dioxide.

The corporate owner of the patent rights, Semet-Solvay Engineering Corporation, might not ring any bells for you, but, according to multiple web-based sources, by the time the enclosed US Patent was issued the company had already been acquired by Allied Chemical, which itself went on, through a series of corporate transformations as Allied Corporation and Allied-Signal, to, finally, undergo a 1999  merger and acquisition with Honeywell, with the Honeywell name being applied to the new entity.

In any case, comment, emphasizing the commercial utility of Carbon Monoxide, and one or two other things, follows excerpts from the enclosed link to and attached file of:

 

"United States Patent 2,128,262 - Carbon Monoxide Manufacture

 

Date: August, 1938

 

Inventor: Louis Newman, Brooklyn

 

Assignee: Semet-Solvay Engineering Corporation, NY

 

Abstract: An object of this invention is to provide an efficient and economical process for the manufacture of carbon monoxide of high purity by the reduction of carbon dioxide.

 

Claims: The process of producing substantially pure carbon monoxide comprising subjecting a body of coke to partial oxidation in one zone to produce a combustible gas and to heat the unoxidized portion of said body of coke substantially to incandescence, burning said combustible gas in another zone  and storing the resultant heat in said other zone, passing carbon dioxide through said heated zone, passing the thus heated carbon dioxide through a body of limestone in a third zone whereby said limestone is decomposed and carbon dioxide produced, and passing the thus produced carbon dioxide through the aforesaid incandescent body of coke to produce carbon monoxide."

------------

 

Now, please note: They are proposing to deliberately manufacture Carbon Dioxide both by oxidizing "coke", i.e., Coal, in  a process which heats more Coal and makes that additional Coal ready for reaction with Carbon Dioxide; and, by using, as we read it, the resultant, hot, CO2-containing exhaust gasses from the coking process to heat limestone, and thereby generate, as in a cement kiln, even more Carbon Dioxide.

All of the Carbon Dioxide is then collected and passed through the already-hot "coke" to produce "substantially pure carbon monoxide".

As we've said before, plain old Carbon Monoxide might not sound all that exciting, until you understand what can be done with it.

And, as just one example of how useful such Carbon Monoxide, made, as herein, from Carbon Dioxide and hot Coal, can be, we remind you of just one of our earlier reports, available on the West Virginia Coal Association's R&D site as:

 

Pittsburgh USBM Hydrogenates Coal with CO & H2O | Research & Development | News.

 

In that report, it was seen that US Bureau of Mines scientists, working in Pittsburgh, PA, had developed a method for "The Hydrogenation of Coal with Carbon Monoxide and Water", with the intent being to prepare "an oil which could then be converted to more volatile fuels by known hydrocracking techniques".

In sum, we can make Carbon Monoxide by reacting reclaimed Carbon Dioxide with red-hot Coal; and, then, we can react that Carbon Monoxide with Water, and more Coal, and thereby produce a raw material from which we can refine, using established technology, "volatile fuels".

And, again, both Coal and Carbon Dioxide, as herein, are raw material resources of potentially great value.
