CO2气氛下乙烷氧化脱氢制乙烯催化剂研究进展

CO2是导致全球变暖的主要温室气体，又是宝贵的可再生C1资源，将其转化为有价值的化学品，在环境保护和碳资源合理利用方面具有双重意义。作为页岩气的重要组成部分，乙烷高效催化转化制乙烯不仅具有重要的理论研究意义，而且具有广阔的工业应用前景。在CO2气氛下乙烷氧化脱氢制乙烯（CO2-ODHE）已成为增产乙烯的有效手段之一。该文重点阐述了在CO2-ODHE反应中不同类型的催化剂及影响该反应催化活性和稳定性的主要因素和关键问题，并对比介绍了乙烷直接氧化脱氢（O2-ODHE）和乙烷化学链氧化脱氢（CL-ODHE）。最后，结合反应机制提出了构筑高效催化剂可能的方向和发展前景。

Research progress of catalysts for oxidative dehydrogenation of ethane to ethylene under CO2 atmosphere

In addition to serving as a major greenhouse gas that contributes to global warming, CO2 is also a valued renewable C1 resource. Converting CO2 into valuable chemicals has dual significance in the aspect of environmental protection and rational utilization of carbon resources. The efficient catalytic conversion of ethane a significant component of shale gas to ethylene not only has important theoretical research significance, but also has broad industrial application prospects. Oxidative dehydrogenation of ethane under CO2 atmosphere (CO2-ODHE) has become one of the most effective means of increasing ethylene production. This paper focuses on the different types of catalysts, and the main factors and the key issues that control and manipulate the catalytic activity and stability of the CO2-ODHE reaction. This review also introduces the oxidative dehydrogenation of ethane (O2-ODHE) and chemical looping oxidative dehydrogenation of ethane (CL-ODHE). Finally, combined with the reaction mechanism, potential directions and development prospects of constructing high efficiency catalyst are put forward.
