摘要: In this work, CO2 methanation has been investigated over Ru-based catalysts. The e ects of promoters on the activity, selectivity and reduction properties of the Ru/sepiolite catalyst were analyzed by kinetic and thermodynamic methods. The catalysts were characterized by means of TPD, and the results revealed that the addition of Mo, Mn or Co improved the properties of the Ru/sepiolite catalyst. The e ects of promoters could a ect the change of enthalpy, entropy and chemical potential.
