aromatic ring, was evaluated over three of the prepared rod-like Fe–Al composite oxides (FeAl-1, FeAl-5 and FeAl-10). The results showed that their reactive activities were in the order of FeAl-5 ≈ FeAl-10 ≫ FeAl-1, which could be attributed to their different pore structural properties and reactive sites caused by the different phase interaction between iron species and the γ-Al2O3. The generation of
在制备的三种棒状Fe-Al复合氧化物(FeAl-1,FeAl- 5和FeAl-10)。结果表明,它们的反应活性约为FeAl-5≈FeAl-10≫ FeAl-1,这可能归因于它们的孔结构性质和反应位点不同,这是由于铁物种与γ-之间的不同相间相互作用引起的。 Al 2 O 3。三氯萘(1,2,3-TrCN和1,2,4-TrCN,即CN-13和CN-14),二氯萘(1,2-DiCN,1,3-DiCN,1,4-DiCN)的生成和2,3-DiCN,即CN-3,CN-4,CN-5和CN-10)和一氯萘(1-MoCN和2-MoCN,即CN-1和CN-2)提示发生了连续的加氢脱氯反应。在三个不同的系统中,CN-14的含量从CN-13的71.5%增至77.7%,这表明在β位置发生了第一个加氢脱氯步骤是优选的。这与八氯萘(CN-75)脱氯过程中在微/纳米Fe 3 O 4上观察到的在α-位置的偏好不同。。一侧和
