Handbook procedure for catalyst testing, illustrated for the example of MoVTeNbOx applied to the propane oxidation reaction. The catalyst test starts with catalyst activation, during which the precursor is exposed to the rather harsh reaction environment for 48 h. Then, the test proceeds with three steps designed to acquire diverse kinetic information. At each measurement point, the steady-state gas-phase concentrations, and thus the alkane conversion and selectivity values, are measured (upper panel) at the chosen reaction conditions (middle and bottom panels). In the figure, T and GHSV stand for temperature and gas-hourly space-velocity, respectively. The figures corresponding to the remaining catalysts and reactions are available in SI.
