| 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. |
