Sonochemical preparation of supported hydrodesulfurization catalysts.

Sonochemical preparation of Co and Ni promoted MoS(2) supported on alumina was achieved by high-intensity ultrasonic irradiation of isodurene solutions containing molybdenum carbonyl, dicobalt octacarbonyl, elemental sulfur, and Al(2)O(3) or Ni-Al(2)O(3) under Ar flow. The sonochemically prepared catalysts were characterized by elemental analysis, XPS, SEM, TEM, and XEDS, and hydrodesulfurizati...

Solid State Synthesis and Characterization of Model Hydrodesulfurization Catalysts

Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of CozlMo,-,S2 with x between 0.025 and 0.3. The solid phases formed during synthesis and after exposure to typical HDS reaction conditions were identified by X-ray diffraction and select...
