Dry reforming of methane (DRM) is an environment friendly process since it utilizes two major greenhouse gases (CH4 and CO2) to produce valuable syngas. Polyol process was adopted to prepare nano supported (Al2O3, ZrO2 and CeO2) Ni based nano catalysts for DRM reaction. All catalysts were prepared in ethylene glycol medium with polyvinylpyrrolidone as a nucleation-protective agent. The main objective of this study was to develop a suitable catalyst, for syngas production, which possessed high activity, stability and minimum coking rate during DRM. The catalytic activities of the prepared catalysts were evaluated in the temperature range 500-800°C. The obtained results revealed that catalytic performance depends on the nature of support. Amongst all tested catalysts, Ni-Zr Pol showed highest activity (87.2%) and stability (%D.F= -0.46). On the other hand Ni-Al Pol catalyst exhibited acceptable activity (84.8%) with minimum coking rate (0.015 g/gcat.h) while Ni-Ce Pol showed smallest activity (83.2%) with large amount of coke deposition (0.025 g/gcat.h)
