选择加氢是去除蒸汽裂解制烯烃过程中所产生微量乙炔的有效方法,高效乙炔选择加氢催化剂的开发具有重要意义。介绍了催化剂类型[单元贵金属、非贵金属及双(多)元金属]及其催化性能,分析了载体、助剂和制备方法对催化剂结构和性能的影响,重点讨论了几何和电子因素对催化剂乙炔选择加氢性能的决定作用。
Choosing hydrogenation is an effective way to remove the trace amount of acetylene produced in steam cracking of olefins. The development of high efficiency acetylene selective hydrogenation catalyst is of great significance. The types of catalyst [unit noble metal, non-precious metal and double (multi) elemental metal] and their catalytic properties were introduced. The influence of carriers, auxiliaries and preparation methods on the structure and properties of the catalyst was analyzed. The effects of geometrical and electronic factors on the catalyst acetylene Select the role of hydrogenation performance.
