Bimetallic Zeolite Catalyst for CO2 Reforming of Methane

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 CO2 conversion equal to 73 and 78, respectively) but monometallic Rh catalysts were the only one stable against coke formation.
