چکیده
Hydroxyapatite (HAp) supported Nickel (Ni) catalyst was prepared using wet impregnation method. A series of Ni/HAp catalysts have been prepared by varying the amount of nickel viz., 3, 6 and 12 %. The highest Brunauer-Emmett-Teller (BET) surface area of 92.18 m/g was noticed for a catalyst composition containing 3% nickel loading. The scanning electron microscopy (SEM) studies revealed a smooth and compact morphology with increasing the nickel loading in the catalyst composition. The performance of the prepared catalysts have been evaluated in steam reforming glycerol process. The percentage hydrogen yield found to depend on water to glycerol ratio employed in the steam reforming process. The catalyst containing 3% nickel content and a water to glycerol ratio of 8:1 has showed a maximum hydrogen yield of 82.2%.

The aim of this research is to study Ni2+ supported on hydroxyapatite-core-shell magnetic γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ni2+) as a green and recyclable catalyst for the Biginelli reaction under solvent-free conditions. One-pot multi-component condensation of 1,3-dicarbonyl compounds, urea and aldehydes at 80 oC affords the corresponding compounds in high yields and in short reaction times ...
متن کاملHydrogen production via steam reforming of LPG on Ni/Zeolite catalysts
Steam reforming is one of the most important processes for producing hydrogen from hydrocarbon fuels such as LPG and has attracted much attention due to its high efficiency and economy. In this study, the LPG steam reforming reaction was investigated on nickel catalysts supported on four various zeolites (H-Y, Na-Y, HZSM5 and Ferrierite). The catalytic tests were performed in a tubular fixed be...
متن کاملStable Hydrogen Production from Ethanol through Steam Reforming Reaction over Nickel-Containing Smectite-Derived Catalyst
Hydrogen production through steam reforming of ethanol was investigated with conventional supported nickel catalysts and a Ni-containing smectite-derived catalyst. The former is initially active, but significant catalyst deactivation occurs during the reaction due to carbon deposition. Side reactions of the decomposition of CO and CH4 are the main reason for the catalyst deactivation, and these...
