MoO 3 /Ȗ-Al 2 O 3 catalyst has been presulfided by ammonium thiosulfate. The effects of the presulfidation methods and the activation conditions on the hydrodesulfurization of thiophene were investigated. The results showed that the catalyst presulfided by ammonium thiosulfate (designated as Mo-ATS)
Raman spectroscopy has been used to characterize various MoOJy-Al,O, and COO (or NiO)-MoO,/y-AI,O, catalysts containing 12 wt% MOO, and 3 wt% COO (or NiO) prepared by different methods. No significant differences between samples prepared by the wet impregnation and the pore volume method could be ob
