Study of Unsupported and Al₂O₃ or SiO₂-Supported Nickel Molybdate for Oxireforming of Ethane

Abstract:

The nickel molybdate unsupported and supported on alumina or silica were prepared by co-precipitation and co-precipitation/impregnation methods and calcined in air at 550°C for 15h. The textural and structural properties of the solids have been studied using Brunner-Emmett-Teller surface analyze (BET), X-ray diffraction (XRD), Laser Raman Spectroscopy (LRS), scanning electron microscopy coupled with energy dispersive X-ray spectrometry (SEM-EDX), temperature-programmed reduction (TPR) and Atomic absorption spectroscopy (AAS). The catalytic activity measurements were performed in a fixed bed quartz reactor under the following experimental conditions: P = 1 atm, Tr = 470- 650 °C, C2H6/O2 = 2 and Wcat = 0.1g. XRD, confirmed par LRS analysis, showed the presence of -NiMoO4 and -NiMoO4 phases. The second one was only observed with the Al2O3 support. The Ni molybdate is a very selective catalyst in oxireforming of ethane with a selectivity consisted between 85 and 100%.
