Abstract

The catalytic Fe/γ-Al2O3 system in air, CO, and H2 atmospheres has been studied in the temperature range of 293–773 K. In the initial state, the system contains at least two Fe3+ paramagnetic forms with close values of isomeric shift and different quadrupole splittings. In this system, iron is reduced to the Fe2+ state in an atmosphere of СО and Н2 at 423–773 K. The latter state also exists in at least two forms. The processes occurring in the system and the nature of the found iron forms are discussed.

摘要

催化铁/γ-Al系2 ö 3在空气中,CO和H系统2个大气压已在温度范围293-773 K的被研究在初始状态下,系统包含至少两个的Fe 3+与顺磁的形式异构位移的接近值和不同的四极分裂。在这个系统中,铁被还原成铁2+状态СО和Н气氛2在423-773 K.后者状态也存在于至少两种形式。讨论了系统中发生的过程和发现的铁形态的性质。
