The Theory of the Interrogative Kinetics Approach State-Defining Experiment To explicitly separate diffusional transport and reaction. To identify the primary kinetic characteristics that can be independently measured in a TAP experiment. To relate the primary kinetic characteristics to detailed reaction mechanisms and distinguish them. State-Altering Experiment To create and kinetically characterize different uniform catalyst states using TAP multi-pulse experiments. To extract the catalyst state characteristics from data obtained in a multi-pulse experiment (particularly the number of active sites). To make assumptions about the reaction mechanism

Interrogative Kinetics A New Methodology for Catalyst Characterization. Application to Furane Oxidation over VPO Catalyst Sergiy O. Shekhtman, Gregory S. Yablonsky, John T.

Multi-Pulse TAP Experiment Furane Oxidation over VPO Catalyst Furane Conversion. Furane/Argon mixture (9/1) was pulsed over oxidized VPO catalyst at 400˚C

Multi-Pulse TAP Experiment Furane Oxidation over VPO Catalyst Furane Basic Kinetic Coefficients over Oxidized and “Relaxed” Catalyst Furane/Argon mixture (9/1) was pulsed over oxidized VPO catalyst at 400˚C. After catalyst had been completely reduced, it was left under vacuum conditions for 14 hrs. The, furane was pulsed again.
