The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced and spent catalysts were studied using the N2 sorption isotherms, XRD, H2-TPR, SEM, TEM and Raman spectroscopy...
In this work, a commercial silica nanopowder was used to prepare nickel based catalysts; Nix/SiO2 (x: 5, 10 and 15 wt. percent), bimetallic catalysts Ni10La10/SiO2 and Ni10Mg10/SiO2 and rhodium promoted catalysts, Ni10Rhx/SiO2 (x: 0.1, 0.225 and 0.5 wt. percent). The catalysts were characterized by N2 sorption, XRD, HRTEM and TPR and tested in dry reforming of methane at low temperature. NiOx nanoparticles...
A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at 650°C for valorization of methane obtained from natural or shale gas: methane dry reforming and at 800°C...
