The catalytic activity of Ni-Rh on the synthesized BEA zeolite in carbon dioxide reforming of methane has been investigated. Catalysts were prepared using the incipient wetness impregnation method, with a total content of metals up to 5 wt%. Catalysts were characterized through XRD, TPR, N2 adsorption, SEM, AAS, TG/DSC analyses. The prepared Ni-Rh zeolites were tested for their catalytic activity at 700 °C, at atmospheric pressure, and at CH4/CO2 ratio of 1. Catalytic results showed that bimetallic based zeolites exhibit high activity (CH4 and CO 2 conversion equal to 73 and 78, respectively) but monometallic Rh catalysts were the only one stable against coke formation. © 2009 Springer Science+Business Media, LLC.

Abstract
The catalytic activity of Ni-Rh on the synthesized BEA zeolite in carbon dioxide reforming of methane has been investigated. Catalysts were prepared using the incipient wetness impregnation method, with a total content of metals up to 5 wt%. Catalysts were characterized through XRD, TPR, N2 adsorption, SEM, AAS, TG/DSC analyses. The prepared Ni-Rh zeolites were tested for their catalytic activity at 700 °C, at atmospheric pressure, and at CH4/CO2 ratio of 1. Catalytic results showed that bimetallic based zeolites exhibit high activity (CH4 and CO 2 conversion equal to 73 and 78, respectively) but monometallic Rh catalysts were the only one stable against coke formation. © 2009 Springer Science+Business Media, LLC.Pubblicazioni consigliate
