โœฆ Synopsis

Abstraot-

The true kinetics of the attack of high temperature graphite by both atomic and diatomic oxygen have been studied using microwave discharge-fast flow system techniques. In the surface temperature range llOO"K-2000ยฐK the oxidation probability for O-atom attack (i) exceeds that for 0s by factors between 5 and as much as 80, (ii) passes through a maximum in this temperature range, as does the 0s attack probability on the same surface, and (iii) is independent of oxygen partial pressure (corresponding to a first order reaction), in contrast to the kinetic order of the Os/carbon reaction. Several mechanistic implications of these results are briefly discussed.

Carbons were prepared from carbonized polyvinylidene chloride (850ยฐC) by activation with CO, at 830ยฐC to 85 per cent burn-off. Characterization of these carbons was made from gas phase adsorption data using nitrogen (77ยฐK) and carbon dioxide (195" and 273ยฐK) as adsorbates in conjunction with the Dub
