摘要
In this work, CO_2 methanation has been investigated over Ru-based catalysts.The effects of promoters on the activity, selectivity and reduction properties of the Ru/sepiolitecatalyst were analyzed by kinetic and thermodynamic methods. The catalysts were characterized bymeans of TPD, and the results revealed that the addition of Mo, Mn or Co improved the properties ofthe Ru/sepiolite catalyst. The effects of promoters could affect the change of enthalpy, entropy andchemical potential.
