In this contribution, we investigate the effect of various reactor parameters on the oxidative dehydrogenation (ODH) of propane using a hexagonal boron nitride (hBN) heterogeneous catalyst. The analysis begins with an assessment of the influence of mass and heat transport on the observed ODH activity. Unexpected experimental results during this analysis prompted us to investigate the use of SiC as an inert catalyst diluent, and we found an increase in propane conversion with increasing diluent content in the reactor. Control experiments suggested that SiC itself is catalytically inactive and that there may be a significant influence of gas-phase chemistry on the observed reactivity.
