We investigate the role of gas-phase phenomena in the heterogeneous oxidative dehydrogenation of propane over hexagonal boron nitride. We apply a recently developed gas-phase combustion model for low-temperature combustion of propane and couple it with several surface microkinetic mechanisms to probe the selectivity limits using the open-source flame solver Cantera. We show that while the conversion of propane is surface-driven, the selectivities are significantly influenced by the gas-phase, especially when dilute catalyst beds are used.<br>

Cobalt Cation

The oxidative dehydrogenation of propane on strontium hydroxyapatites (SrHAp) and the hydroxyapatite incorporated with cobalt cation (Co-SrHAp) were tested and related to H-D exchangeability of OH groups in those hydroxyapatites with D2O. With increasing Co2+ contents in those catalysts, the oxidative dehydrogenation of propane and H-D exchangeability of HO groups in those hydroxyapatites with D2O were enhanced. It is suggested that "oxygen-species" derived from the abstraction of hydrogen of OH groups directly contributes to the hydrogen abstraction from propane on those catalysts.
