Reaction rates based on the Boudouard reaction using a Langmuir-Hinshelwood type equation were analyzed to investigate the effect of the heat treatment temperature on the reactivity of glass-like carbon made from furan resin with carbon dioxide. Glass-like carbons were prepared from furan resin at 1000 degrees C, 1500 degrees C and 2000 degrees C. Oxidation was performed in the range from 925 degrees C to 1100 degrees C in a batch reactor. The binding energy of carbon-carbon in the glass-like carbon was found to increase with increasing heat treatment temperature. Contrarily, the binding energy between carbon and oxygen in a functional group was found to decrease with increasing heat treatment temperature. The oxidation resistance of glass-like carbons especially those heat-treated at high temperatures was concluded to be relatively excellent compared with other carbons such as graphite because the functional group containing oxygen was hard to form on glass-like carbon and the decomposition of the functional group into carbon monoxide was thought to be difficult.
