| 摘 要： | 综述了近年来国内外有关利用逆水煤气变换耦合乙烷脱氢制备乙烯反应的研究状况。SiO2和Silicalie-2分子筛担载的铬、锰、铁及稀土氧化物催化剂具有较好的催化活性。催化剂表面碱性位的存在有利于CO2的活化，消除乙烷脱氢产物H2和表面积炭，提高反应活性及催化剂的稳定性。进一步提高活性的关键是选择适且的催化剂，以增加CO2的加氢活性。该耦合反应也是充分利用低碳烷烃和CO2资源的新途径。

| Abstract: | A review is presented on coupling of dehydrogenation of ethane with reversed water\|gas shift reaction for ethylene synthesis. The SiO\-2 and Silicalite\|2 supported chromium, manganese and iron oxide catalysts were found to exhibit a high performance in the dehydrogenation of ethane in the presence of CO\-2. CO\-2 can be activated by the surface basicity. The results show that the synergetic action of acidity and basicity is important to the increase of the catalytic activity. The function of CO\-2 is to abstract H\-2 and to resistant coke formation during the dehydrogenation of ethane. The reaction mechanism and effects of reaction condition on the dehydrogenation of ethane were also evaluated. |
