Carbon recovery from CO2 and CO containing gas Use as raw material for ironmaking
The steel industry, which emits the largest amount of carbon dioxide (CO2), is required to reduce its CO2 emissions as soon as possible. A process for recovering and recycling solid carbon from gases containing CO2 and carbon monoxide (CO) is known. This process uses water gas shift reaction (CO2+H2→CO+H2O) and carbon deposition reaction (2CO→C+CO2, CO+H2→C+H2O). However, there has been concern that the precipitated carbon is fine and difficult to recover. This invention enables carbon recovery from CO2 and CO in gas by using porous fibrous iron (iron whisker) as a carbon deposition site. Furthermore, iron raw materials containing carbon could be used directly in the ironmaking process. This may lead to the carbon cycle process in the ironmaking process.
