| 摘 要： | 在Ｍｎ２Ｏ３／ＳｉＯ２催化剂上，当总空速为２０００ｈ－１，ｎ（Ｃ２Ｈ６）／ｎ（Ｏ２）＝１，反应温度为７５０℃时，乙烷生成乙烯的收率达４５７６％；温度为８８０℃时，乙烯收率为６１４３％。添加水蒸汽可使催化剂活性稳定。根据该反应的宏观动力学研究，推出动力学方程为ｒＣ２Ｈ４＝ｋｐ２Ｃ２Ｈ６，并对反应机理进行了讨论。

| Abstract: | The oxidative dehydrogenation of ethane in wet natural gas to ethylene has been studied over Mn2O3/SiO2 Catalyst.A yield of 45.76% is obtained at 750 and 61.43% at 880 at a space velocity of 2 000 h-1 and n(C2H6)n(O2)=11.In the presence of steam,the activity of the catalyst is almost same with that without steam.Macrokinetic study gives a rate equation of rC2H4=kp2C2H6 Finally,the reaction mechanism was discussed. |
