TRANSIENT KINETIC TECHNIQUES FOR DETAILED INSIGHT IN GAS SOLID REACTIONS

Transient kinetic studies with application of labeled molecules form a powerful tool to investigate in situ gas-solid interactions, to obtain fundamental and mechanistic information, like concentrations of active sites and intrinsic rate constants. Especially in the field of carbon gasification, this approach is extremely valuable; due to the high temperatures involved, other techniques are difficult to apply in situ. A short review is given on the kinetic studies of the carbon gasification with CO2 and the potential value of transient techniques in the study of gasification reactions.
