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.
