研究了工业Pt/Al_2O_3催化剂上丙烷脱氢与硝基苯加氢的反应耦合。使用固定床反应器研究了偶联、催化剂的使用和反应温度的影响。即使不使用催化剂，这两个反应的耦合也大大增加了丙烷和硝基苯的转化率。Pt/Al 2 O3催化剂的使用进一步提高了丙烯和硝基苯加氢产物的转化率和选择性。较高的反应温度有利于热解产物的选择性。反应途径勾勒来解释我们的实验结果。
Reaction coupling between propane dehydrogenation and nitrobenzene hydrogenation over a commercial Pt/Al2O3catalyst is presented. The effects of coupling, use of the catalyst, and reaction temperature were studied using a fixed-bed reactor. The coupling of the two reactions drastically increased propane and nitrobenzene conversions even without the use of the catalyst. The use of Pt/Al2O3further increased the conversions and the selectivity towards propylene and nitrobenzene hydrogenation products. Higher reaction temperatures favored the selectivity towards pyrolysis products. Reaction pathways are sketched to explain our experimental findings.
