Resumen:
In order to abate diesel soot particles many catalysts have been studied at several industrial and academic
laboratories. However, the comparison of kinetic data obtained with such catalysts is not straightforward,
due to the different experimental conditions used in the activity measurement carried out by each
research group. Temperature-programmed analysis is the most common technique used to determine
catalytic activity for soot oxidation. For a given catalyst, the temperature-programmed oxidation profile
depends on variables such as heating rate, oxygen partial pressure, gas flow rate, catalyst:soot weight
ratio, type of contact between the catalyst and the soot, and existence of energy and/or mass transfer
limitations during the analysis. This work presents a systematic study of the influence of all these testing
variables on the TPO profile, and the optimum testing conditions to obtain good reproducibility during
the kinetic study. Both experimental and computer simulation results are included to assist researchers
in the comparison of results obtained under different experimental conditions.
