Abstract
A method of hydrogenating carbon dioxide, the method may include introducing a feed stream comprising carbon dioxide and hydrogen to a reactor. The method may include reacting the carbon dioxide with the hydrogen at a temperature at least 550° C. in the presence of a catalyst to produce carbon monoxide and water. The catalyst may comprises a metal oxide support and a promoter. The promoter may consist of alkali metals. The catalyst may have a carbon monoxide selectivity greater than 90%.
