Gravimetric studies, at 25 to 733 C, indicate that the initial weight changes of clean graphite, when exposed to flowing CO/sub 2/, CO, or O/sub 2/, are almost entirely caused by physical adsorption processes. An upper limit of 1.4 x 10/sup 1//sup 7/ chemisorption sites/gram was determined for reactor electrographite. Displacement of physically-adsorbed CO by CO/sub 2/ can lead to the appearance in the gas phase of the same quantity of CO as would be released by chemisorption of CO/sub 2/ in the reaction, C/sub f/ + CO/sub 2/ yields C(O) + CO. The results must be considered in proposing or evaluating models for the CO/sub 2/-graphite reaction. Kinetic equations, which describe the rate of adsorption as a function of the available area, were derived. (auth)
