The deactivation also caused the selectivity of both propane and propylene decreased.
而失活使丙烯、丙烷的选择性下降。

It is a challenging research topic to obtain higher propane conversion and higher propylene selectivity at the same time in the reaction of propane oxidative dehydrogenation (ODH).
在丙烷氧化脱氢反应中，同时获得高的丙烷转化率和丙烯选择性是具有挑战性的研究内容之一。
