Dry (CO2) reforming of methane is conducted over two newly synthesized Ni20/Ce-gamma Al2O3 and Ni20/Ce-meso-Al2O3 catalysts. The x-ray diffraction (XRD) patterns indicated that Ni20/Ce-meso-Al2O3 exhibits a better dispersion of nickel, while Ni20/Ce-gamma Al2O3 has larger amounts of nickel crystallites. The temperature programmed desorption (TPD) kinetics analysis indicated that Ni20/Ce-meso-Al2O3 had a lesser metal-support interaction than the Ni20/Ce-gamma Al2O3. The thermal gravimetric analysis (TGA) indicated that the incorporation of ceria into the Al2O3 matrix helps to stabilize Ni20/Ce-meso-Al2O3 during dry reforming of methane. The temperature programmed reduction (TPR) indicated that the synthesized catalysts were sufficiently reducible below 750 degrees C. A fixed bed reactor evaluation (at 750 degrees C) showed that both catalysts can facilitate methane reforming to syngas with minimal coking throughout the 30 hours time-on-stream (TOS). However, Ni20/Ce-meso-Al2O3 is more promising in terms of prolonged stability for dry reforming applications. Moreover, the syngas yield for Ni20/Ce-gamma Al2O3 is close to equilibrium prediction during the first 1 hour of reaction time.
