ABSTRACT

In the present work, the crystallographic properties of unsupported Ni-Mo catalyst serie were carried out. They were synthesized with a ratio of Mo from 10, 25, 50 to 75 wt%. The final catalysts were characterized by X-ray diffraction (XRD) in order to identify crystallographic phases present in the solids using DRXwinsoftware version 2.3. The crystal size was determinated by Bragg’s law. Ni-Mo catalyst model (MoC-75) structure was modeled by Carine Crystallography Software version 3.1 which was built based on its space group and atomic positions which were previous the results of XRD. Characteristical phases of Ni-Mo Carbides were identified for their typical planes (111), (200) and (311) for Ni-Mo series and the plane (101) for the a Mo-C series.
