Abstract
A process for a gas phase thermochemical reduction of oxygenated gas, such as carbon dioxide (CO2), by a solid activated charcoal to obtain premium grade, very high purity, carbon monoxide (CO) product. Whereby granular activated carbon (GAC) or powdered activated carbon (PAC) via a high temperature Reverse Boudouard Reduction Reaction (RBRR) using an oxygen exchange mechanism (OEM), is used to yield the carbon monoxide (CO) product in both a non-catalytic and a catalytic reactor.
Claims20
A process comprising:
- directing carbon dioxide into a mixer;
- releasing an activated carbon from a storage bin for combining with said carbon dioxide, wherein said activated carbon comprises a biomass charcoal;
- combining, with said mixer, said carbon dioxide with said activated carbon;
- feed stocking said mixed activated carbon and carbon dioxide to a Reverse Boudouard Reduction reactor unit;
- heating said Reverse Boudouard Reduction reactor unit containing said mixed activated carbon and carbon dioxide with a high temperature furnace to produce a carbon monoxide product, wherein a steel forge grade renewable charcoal fuel is configured to provide a first source of fuel for said high temperature furnace;
- filtering said carbon monoxide product in a high temperature bag house, wherein said filtering is configured to remove at least a portion of entrained activated carbon particles, and wherein said carbon monoxide product is substantially a result of a Reverse Boudouard Reaction from said reactor unit;
- splitting said filtered carbon monoxide product into a first carbon monoxide product stream and second carbon monoxide product stream;
- conveying at least a portion of said first carbon monoxide product stream back to said high temperature furnace, wherein said first carbon monoxide product stream is configured to provide at least a portion of a second source of fuel for said high temperature furnace;
- directing a substantial portion of said second carbon monoxide product stream to a heat exchanger, said heat exchanger being configured to be operable for cooling said second carbon monoxide product stream.
