New technology for converting CO2 to CO developed with potential for application in steel sector
Science and Technology
A new energy-efficient carbon dioxide capture technology has been developed that converts carbon dioxide into carbon monoxide under electro catalytic conditions at ambient temperature in the presence of water, with the potential for use in the steel sector. Carbon monoxide (CO) is a chemical widely used in industry, especially as syn gas. In the steel industry, CO is an essential component for converting iron ores into metallic iron in blast furnaces. Currently, CO is produced from partial oxidation of coke/coal, leading to significant production of CO2 as an end product of this process. If this emitted CO2 can be captured and converted into CO, it could lead to a circular economy while reducing the carbon footprint and associated costs in the process. The CO2 to CO conversion process that is currently in wide use occurs at elevated temperatures (400–750 °C), and the presence of equivalent amounts of H2 to drive this reaction makes it an energy-intensive process. .
