摘要

耐硫甲烷化工艺对含硫气氛和低H2/CO比均有良好的适应性

是甲烷化技术发展的重要方向。其中Mo基催化剂是研究最为广泛的耐硫甲烷化催化剂。重点介绍了Al2O3、ZrO2、CeO2和CeO2-Al2O3载体以及CoO、NiO助剂对Mo基催化剂耐硫甲烷化性能的影响;分析了催化剂的硫化机理以及CoO、NiO助剂和CeO2载体在硫化过程中的作用

指出硫化温度是影响催化剂的物种分布和催化性能的重要因素;阐述了耐硫甲烷化反应的机理;对甲烷化催化剂的研究方向进行展望。

Abstract

Sulfur-resistant methanation have been investigated for their insensitivity to sulfur poisoning and high activities in the methanation reaction with low H2/CO ratios. Molybdenum-based catalysts were studied widely in literature. The effects of Al2O3

ZrO2

CeO2 and CeO2-Al2O3 supports

and CoO and NiO promoters on the performance of methanation catalysts were mainly introduced. The sulfidation mechanism for MoO3 and CoO/NiO promoted MoO3 catalysts and CeO2 support was critically analyzed based on the reported works. It was pointed out that the sulfidation temperature was a key factor to catalyst morphology. In addition

the mechanism of sulfur-resistant methanation was discussed. An overview regarding the opportunities for future research in sulfur-resistant methanation of CO was provided.
