NiAgYO catalyst prepared using sol–gel method exhibited better catalytic behavior than NiAgO for the direct conversion of ethane to ethylene oxide (EO). An optimal EO yield of 7.6% with 19.8% selectivity was obtained at 290°C. The catalysts were characterized by X-ray diffraction (XRD), H 2 temperature-programmed reduction (H 2 -TPR), O 2 temperature-programmed desorption (O...
The use of a Ni-Ag-O catalyst in a one-step reaction to produce ethylene oxide from ethane was investigated. An optimum ethylene oxide yield of 1.2% was obtained with a selectivity of 12.8% at 310°C. The catalyst was characterized through X-ray diffraction, BET surface area, H 2 temperature-programmed reduction, O 2 temperature-programmed desorption and X-ray photoelectron spectroscopy...
