Abstract

A systematic temperature-programmed desorption (TPD) study of Mn-Fe catalysts was conducted. Hydrogen chemisorption on Mn-Fe catalysts is a highly activated process. Fe, MnO and MnFe₂O₄ related desorption spectra have been assigned. Hydrogen does adsorb on the spinel phase (MnFe₂O₄) in the form of activated adsorption. Carbon monoxide does not adsorb on the spinel phase. The results suggest that the spinel phase alone may not be an active phase for syngas conversion.

锰铁催化剂的程序升温解吸研究

对Mn-Fe催化剂进行了系统的程序升温解吸(TPD)研究。氢在Mn-Fe催化剂上的化学吸附是一个高度活化的过程。确定了Fe、MnO和MnFe2O4的解吸光谱。氢以活化吸附的形式吸附在尖晶石相(MnFe2O4)上。一氧化碳不吸附在尖晶石相上。结果表明，尖晶石相本身可能不是合成气转化的活跃相。
