Effect of nanostructure, oxidative pressure and extent of oxidation on model carbon reactivity

Oxidation kinetics and fringe analysis studies of three “model” carbons, ranging from fullerenic to onion-like nanostructures and a reference diesel soot were performed in a thermogravimetric analyzer. The samples were oxidized isothermally at temperatures ranging from 575 to 775°C in air. Multiple tests were performed to obtain the most favorable operating conditions to minimize mass-transfer diffusion limitations in the experiments.
