“…The activation energy was calculated as 41.8 kJ mol −1 . [13]. Correlation was observed between the catalytic activity and the reducibility of a nickel salt, which indicates that metallic nickel, rather than nickel oxide, is active sites responsible for carbon gasification.…”

A new method determining the specific rate with no information about the number of active sites was applied to the reverse-Boudourad reaction over supported Ni catalysts. It was found that the catalyst support hardly affected the specific rate. The activity pattern and activation energies agreed well with those obtained by a conventional method using TG, suggesting the validity of the new method for studying the kinetics.

“…It appears that the mechanism of gasification is very similar for the three catalysts. As suggested by earlier studies [8,12], the C-• C bond breaking next to a surface carbon-oxygen complex to produce CO2 (or CO at higher temperatures) is the likely ratedetermining step for carbon gasification. There is a great deal of supporting evidence for this model, including oxygen-and carbon-labeled isotope studies and temperature-programmed .…”
