Effect of Ru and Sn Additives on the Activity and Stability of Ni-based Catalyst for Coupling Methane Partial Oxidation and Carbon Dioxide Reforming
【摘要】 利用浸渍法制备了钌和锡掺杂镍系催化剂,考察了其耦合甲烷部分氧化与二氧化碳重整的活性和稳定性。结果表明:添加金属钌和锡均降低了催化剂耦合甲烷部分氧化与二氧化碳重整的活性和稳定性。
【Abstract】 Ni-based catalysts doped Ru and/or Sn were prepared by impregnation method,and their activity and stability in coupling methane partial oxidation and carbon dioxide reforming were observed.It was found that doped Ru and Sn both decreased the activity and stability of the catalysts.
