The heterogeneous reactions of solid carbon reacting with gaseous carbon dioxide and steam have been studied under high-pressure and high-temperature conditions. The high-pressure shock tube facility at the University of Illinois at Chicago was used to perform experiments with post-shock pressures ranging from 40 to 412 atm, temperatures ranging between 1404 and 2534 K, and nominal reaction times of 1 ms. Amorphous carbon particles were injected into the shock tube by means of a particle injector specifically designed for these experiments. The carbon particles were injected into the shock tube containing mixtures of varying concentrations of H2O or CO2 in Ar as balance. The overall reaction rates have been calculated and compared to rates of previous theoretical and experimental values. The wide temperature range of the experimental conditions allowed for the observation of both reaction- and transport-limiting regimes. Using theoretical techniques for computing the species transport properties, the transition temperatures where transport dominates the reaction were determined and match the experimental results.
