Abstract

Zn-hydroxyapatites supports were synthesized with a variable Zn content (0-15% mol Zn). Samples were  dried at 80°C for  24  h  before  being  impregnated  with  a  Mo  salt  (as  15%  MoO3)  and  a  Ni  salt  (3  Mo:  Ni  atomic  ratio).  After impregnation,  solids  were  divided  in  two  portions:  one  portion  was  calcined  at  400°C  and,  the  other  one  at  800  °C respectively for 4 h. These samples were characterized by different techniques such as:  X-ray diffraction (XRD), FT-IR spectroscopy, transmission electron microscopy (TEM), temperature programmed reduction (TPR) and BET surface area measurements. Results showed that calcination temperature, and the Zn content into the hydroxyapatite structure, play an important role on textural properties of these potential catalysts for hydrodesulfurization reaction of thiophene.
