掌握高选择性的费-托合成铁催化剂的制备规律是尚未解决而极为重要的课题。 本工作用~(57)Fe穆斯堡尔谱、高分辨电镜观察不同铁盐浸渍液、担体及预处理条件制备的铁/担体催化剂,
To master the preparation of highly selective Fischer-Tropsch synthesis catalyst is an unresolved and extremely important issue. In this work, Fe (superscript 2+) Fessbauer spectroscopy and high resolution electron microscopy were used to observe the iron / support catalysts prepared under different conditions of ferric salt immersion, support and pretreatment.
