摘要
介绍了CO2选择氧化乙苯制苯乙烯催化剂研究现状及发展态势。按载体,CO2选择氧化乙苯制苯乙烯催化剂主要分为活性炭、氧化铝、水滑石、氧化镁及其他5种类型,目前存在的主要问题是失活速度较快,稳定性较差。反应按氧化-还原循环和反应耦合2种机理进行。在催化剂表面,酸、碱中心匹配对催化剂的性能有重要影响。
The catalyst used in the selective oxidation dehydrogenation of ethylbenzene to styrene with carbon dioxide was reviewed. Reserachers made much progress in this processs,however, the catalyst deactivated very soon and its stability was lowly. It was important for the application of this process to improve the catalyst activation, especially enhance their catalytic stability by further investigating the mechanism of catalyst and deactivation.
