Abstract
Abstract An improved method of producing carbon monoxide in a plasma arc reactor is disclosed, wherein carbon dioxide is delivered to an arc to form a plasma into which solid carbon is delivered. The products are quenched and filtered to yield carbon monoxide. High yields of carbon monoxide of high purity and high efficiencies of electrical-to-chemical conversion thus may be achieved.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A method of producing carbon monoxide comprising the steps of: delivering a first stream of carbon dioxide to an arc to form a plasma, delivering solid carbon to the plasma, at least a portion of said solid carbon delivered to the plasma from an electrode of solid carbon, and at least a portion of said solid carbon delivered to the plasma in powdered form, said solid carbon powder carried by a second stream of carbon dioxide and injected into the plasma ahead of the arc, and quenching the resultant products.
Claim 2
Independent Claim
90 words
A method of producing carbon monoxide comprising the steps of: delivering a first stream of carbon dioxide to an arc to form a plasma, delivering solid carbon to the plasma, at least a portion of said solid carbon delivered to the plasma from an electrode of solid carbon, and at least a portion of said solid carbon delivered to the plasma in powdered form, said solid carbon powder carried by a second stream of carbon dioxide and injected into the plasma ahead of the arc, and quenching the resultant products.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein the first stream of carbon dioxide is injected ahead of the second stream of carbon dioxide carrying said solid carbon powder.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein carbon dioxide is caused to flow along the electrode of solid carbon so as to inhibit short circuits from deposited carbon.
Claim 5
Dependent Claim
27 words
The method of claim 3 wherein the first stream of carbon dioxide is injected ahead of the second stream of carbon dioxide carrying said solid carbon powder.
Claim 6
Dependent Claim
18 words
The method of claim 1 further comprising the step of filtering the quenched products to remove carbon therefrom.
