In the oxydehydrogenation of ethylbenzene an active coke,formed in the course of the reaction,is the catalytically active material.

在乙脱氢过程,生成了一种活性焦炭,这是一种具有活性的物质。

The team identified 42 such molecules and settled on four to track with the nanoparticles: decane, trimethylbenzene, ethylbenzene, and heptanol.

研究小组确认了42种这样的分子，选4种，利用纳米级粒子进行跟踪监测。
