The analysis of char gasification in CO/sub 2/ using the transient kinetic approach gives a direct measurement of the reactive surface area of chars. The use of this technique has also provided the heretofore elusive quantitative experimental explanation of reactivity variations with conversion. It was found that the ratio of the reactive surface area of a bituminous coal char to its active surface area is not constant, but varies as a function of conversion. Turnover frequencies for char gasification in CO/sub 2/ have been determined. Preliminary experiments suggest that char gasification may be a structure-sensitive reaction.
