This paper reports the stability and promotional influence of ceria addition to the activity of Co-Ni/Alumina catalyst during CO2 reforming of propane. Catalyst samples with 6 different Ce loading were prepared via impregnation at pH = 2. Specimens were characterized using BET, NH3-TPD, TPR-TPO, CO2-TPD and H2 chemisorption. Experiments were conducted in 17 mm ID quartz reactor at atmospheric pressure over 500-750 oC. While BET surface area decreased with increases in Ce loading, the concentration of acidic site (from NH3-TPD) increased with ceria although there was no discernible change in the concentration of basic sites. The dry reforming reaction initially increased with ceria loading attaining a maximum at about 1.2 wt %. However, the catalyst activity dropped only gradually with further ceria addition. Even so, the catalyst with 1 % ceria loading still exhibited higher activity than unpromoted Co-Ni. TOC analysis of used catalysts revealed only mild (< 8%) carbon content suggesting that the presence of ceria improved catalyst resilience to carbon deposition. Kinetic measurements were obtained from the optimum catalyst. Addition of ceria also approved to have a lowering effect on the activation energy (from 86 to 67 kJ mol-1). A power low fit of the rate data also revealed positive under dependencies on both C3H8 (zero) and CO2 (1.2). Detailed mechanistic analysis of the data are provided in the full length paper.
