One‐Pot Preparation of Ni2P/γ‐Al2O3 Catalyst for Dehydrogenation of Propane to Propylene

The γ‐Al2O3 supported Ni2P catalysts for propane dehydrogenation were prepared by one‐pot method and evaluated to study the platinum‐like behaviour of Ni2P. The catalysts were characterized by X‐ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy‐dispersive X‐ray Spectrometer (EDS), N2...

Description
Summary:The γ‐Al2O3 supported Ni2P catalysts for propane dehydrogenation were prepared by one‐pot method and evaluated to study the platinum‐like behaviour of Ni2P. The catalysts were characterized by X‐ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy‐dispersive X‐ray Spectrometer (EDS), N2 adsorption at −196 oC and temperature‐programmed desorption of ammonia (NH3‐TPD). Results show that Ni2P is beneficial to the catalytic stability. It exhibits higher conversion for PDH of 23.8% and propylene selectivity of 74.4%. Ni2P was directly synthesised on the support γ‐Al2O3 to prepare the catalyst Ni2P/γ‐Al2O3. 20%Ni2P/γ‐Al2O3 shows a lasting high activity unlike 0.5%Pt/γ‐Al2O3 for 600 min. It exhibits conversion for PDH nearby 20% and propylene selectivity about 70%
