Reaction of Carbon Monoxide with Graphitic Carbon at 450° C.

Abstract

PUBLISHED investigations of researches on the reaction of carbon monoxide with carbonaceous solids have been concerned with the Boudouard reaction, 2CO ⇄ C + CO₂. Many measurements have been reported above 500° C. in which range the rate of reaction is appreciable and the resultant partial pressure of carbon dioxide is measurable. Below 500° C. the observed partial pressure of carbon dioxide is so low that it cannot be differentiated experimentally from that normally expected on outgassing such materials, although the equilibrium values for the carbon dioxide are higher than those above 500° C.
