CO2 Methanation Over Ni in SiO2-Al2O3 Catalysts Effect of Ba La and Ce Addition by nthienanh29 is a document available to read on EtoBox.
This article investigates the CO2 methanation process using Ni/SiO2–Al2O3 catalysts modified with Ba, La, and Ce as promoters. The study finds that the addition of these promoters significantly enhances catalytic activity, with the Ba-promoted catalyst achieving a maximum CO2 conversion of 85.6% at 400 °C. Characterization techniques reveal that the performance is influenced by surface basic sites and Ni dispersion, highlighting the potential of these modified catalysts for efficient CO2 hydrogenation to me
