| 摘 要： | 对Mn2O_3／SiO_2催化剂上湿大然气中的乙烷氧化脱氢反应进行了研究，发现Mn2O_3／SiO_2有较好的催化活性。对反应前后的催化剂进行了XRD和XPS分析，结果表明，催化剂的活性组分为Mn~3 我们认为在该催化剂上乙烷的主要活化途径是：催化剂表面的配位不饱和酸碱对（MLC~n -OLC~2-C）将吸附在它们上面的C_2H_6活化和异裂成乙基向由基，乙基自由基进一步形成C_2H_4，同时反应物O_2与催化剂作用，促使已基自由基进行脱附。

| Abstract: | The oxidative dehydrogenation of ethane in Wet natural gas over an Mn2O3/SiO2 catalyst has been investigated. The selectivity to C2H4reaches 88.71% and the yield of C2H4 is 45.52% under the conditions of aC2H6O2 mole ratio of 1, wet natural gas SV of 2000 h-1, atmospheric pressure and 750oC. The catalysts before and after reaction were analyzed by XRD and XPS. The results show that the structure and activity of the catalyst are stable and the active components on the catalyst are Mn3+. The main activation process of ethane over Mn2O3/SiO2 is suggested. |
