Synthesis Of Nano Ni-Mo/γ-Al2O3 CatalystSynthesis Of Nano Ni-Mo/γ-Al2O3 Catalyst

Abstract

Nano γ-Al₂O₃ support was prepared by co-precipitation method by using different calcination temperatures (550, 600, and 750) ^oC. Then nano NiMo/γ-Al₂O₃ catalyst was prepared by impregnation method were nickel carbonate (source of Ni) and ammonium paramolybdate (source of Mo) on the best prepared nano γ-Al₂O₃ support at calcination temperature 550 ^oC. Make the characterizations for prepared nano γ-Al₂O₃ support at different temperatures and for nano NiMo/γ-Al₂O₃ catalyst like X-ray diffraction, X-ray fluorescent, AFM, SEM, BET surface area, and pore volume.

The Ni and Mo percentages in the prepared nano NiMo/γ-Al₂O₃ catalyst determined by X-ray fluorescence were 2.924 wt % and 12.9 wt %, respectively. SEM of prepared nano γ-Al₂O₃ support at calcination temperature 550 ^oC. The average particles diameter of prepared γ-Al₂O₃ support determined by AFM at calcination temperatures 550, 600, and 750 ^oC and for prepared nano NiMo/γ-Al₂O₃ catalyst at calcination temperature 550 ^oC.
