(621de) Bi-Reforming of Methane at Low Temperatures over Pt or Pd (Ni-Mg/ceria-zirconia) Catalysts Conference: AIChE Annual MeetingYear: 2015Proceeding: 2015 AIChE Annual MeetingGroup: Catalysis and Reaction Engineering DivisionSession: Poster Session: Catalysis and Reaction Engineering (CRE) Division Time: Wednesday, November 11, 2015 - 6:00pm-8:00pm Authors: Elsayed, N., University of South Florida Roberts, N., University of South Florida Joseph, B., University of South Florida Kuhn, J. N., University of South Florida Bi-reforming (combined steam and CO2 reforming) of methane was studied over platinum (0.5, 2 wt. %) or palladium (0.5, 2 wt. %) and/or nickel (8 wt. %) and magnesium (8 wt. %) immobilized onto a ceria-zirconia support. XRD patterns demonstrated that the support was a cubic fluorite structure and Ni and Mg were immobilized onto it. Temperature-programmed reduction showed that addition of Pt or Pd substantially decreased the reduction temperature. CO2 desorption studies indicated that the metals had an impact on the basicity of the catalysts. Bi-reforming studies also showed that addition of Pt or Pd improved the H2:CO ratio.
