dc.description.abstract | Designing an economically viable catalyst that maintains high catalytic activity and stability is
the key to unlock dry reforming of methane (DRM) as a primary strategy for biogas
valorization. Ni/Al2O3 catalysts have been widely used for this purpose; however, several
modifications have been reported in the last years in order to prevent coke deposition and
deactivation of the samples. Modification of the acidity of the support and the addition of
noble metal promoters are between the most reported strategies. Nevertheless, in the task of
designing an active and stable catalyst for DRM, the selection of an appropriate noble metal
promoter is turning more challenging owing to the lack of homogeneity of the different studies.
Therefore, this research aims to compare Ru (0.50 and 2.0%) and Re (0.50 and 2.0%) as
noble metal promoters for a Ni/MgAl2O4 catalyst under the same synthesis and reaction
conditions. Catalysts were characterized by XRF, BET, XRD, TPR, hydrogen chemisorption
(H2-TPD), and dry reforming reaction tests. Results show that both promoters increase Ni
reducibility and dispersion. However, Ru seems a better promoter for DRM since 0.50% of Ru
increases the catalytic activity in 10% and leads to less coke deposition. | es |
