Syngas Production From CO2 Reforming Of Methane Over Neodymium Sesquioxide Supported Cobalt Catalyst

Abstract

This paper reports for the first time the catalytic dry (CO2) reforming of methane over 20 wt%Co/80 wt% Nd2O3 catalyst. The catalyst was synthesized by wet-impregnation procedure and its physicochemical properties were characterized by TGA, XRD, FESEM, EDX, FTIR, H2-TPR and TPD followed by activity testing in a fixed-bed reactor. The effects of feed ratios (CH4: CO2) ranged 0.1e1.0, reactant (CH4 and CO2) partial pressure (0e50 kPa) and temperature ranged 923e1023 K on the activity of the catalyst were investigated. The conversion of both reactants increased with the feed ratio and reaction temperature reaching maximumvalues of 62.7% and 82% for CH4 and CO2, respectively.
