综述了铁酸盐系列催化剂(Fe系催化剂)在丁烯氧化脱氢反应中的应用研究进展,介绍了Fe系催化剂的活性中心和氧化脱氢机理,分析了催化剂的失活原因,详述了助剂对Fe系催化剂催化性能的影响,并对Fe系催化剂的发展方向进行了展望。开发出高反应活性、高选择性和高强度的新一代Fe系丁烯氧化脱氢制丁二烯的高效催化剂,是今后的主要研究方向,同时,开发资源利用率高、低投资、低生产成本和废水量少的丁烯氧化脱氢工艺也非常关键。

The progresses of ferrites(Fe-based)catalysts for butene oxidative dehydrogenation were reviewed.The active sites and the catalytic mechanisms of the Fe catalysts for butane oxidative dehydrogenation were introduced.The reasons of deactivation of the catalysts and the effects of additives on performance of the Fe catalysts were summarized and the development direction of Fe catalysts was also discussed.It was forecasted that developing a new generation of Fe-based catalyst with higher activity,selectivity and strength for butene oxidative dehydrogenation would be the main research direction in the future.Meanwhile,developing the butene oxidative dehydrogenation process with higher resource utilization,lower investment,lower production cost and less amount of wastewater were also very critical.
