Abstract:

CeO₂-SiO₂(C-S) Binary Oxides Were Prepared by Deposition Precipitation as Modified Support. Nanoparticle Nickel Catalysts (5 Wt.%), Supported on SiO₂ and CeO₂-SiO₂ Were Prepared by Impregnation. Catalysts Were Identified by Several Characterizations (XRD, BET, TPR, TPD and TEM). the Analyses Showed that Nanoparticle Ni Supported on CeO₂-SiO₂ Catalysts Gave Better Properties in Reducibility, Basicity, Ni Metal Dispersion and Size Compared to the Nickel Catalysts Supported on the Single Oxide SiO₂. the Catalytic Test of Dry Reforming of CH₄ with CO₂ (DRMC) Reaction Was Conducted Using Temperature Programmed Reaction (TPRn) Technique which Connected to an Online Mass Spectrometer. the Catalytic Test Showed that Ceria (CeO₂) Loading Influenced the Activity, Mainly the Hydrogen Production. Ni Catalyst with 9 Wt.% of Ceria Exhibited the Highest Hydrogen Production and it Was Suggested to Be the Optimum Value of Ceria Loading. in Addition, the Lower Amount of Carbon Was Observed on the Ni/9C-S Catalyst. this Revealed that the Addition of an Appropriate Amount of Ceria Increased the Hydrogen Production and Reduced the Carbon Formation.
