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.

反应器参数对氮化硼催化丙烷氧化脱氢的影响

在这项贡献中，我们使用六方氮化硼（hBN）非均相催化剂研究了各种反应器参数对丙烷的氧化脱氢（ODH）的影响。该分析从评估质量和热传输对所观察到的ODH活性的影响开始。该分析过程中出乎意料的实验结果促使我们研究将SiC用作惰性催化剂稀释剂，并且我们发现丙烷转化率随反应器中稀释剂含量的增加而增加。对照实验表明，SiC本身是催化惰性的，气相化学对观察到的反应性可能有重大影响。
