Adsorption of Sulfur Compounds by Hydrodesulfurization Catalysts

Adsorption and Desorption of Sulfur Compounds by Improved Nano Adsorbent: Optimization Using Response Surface Methodology

Today, sulfur removal from fuels has improved by new adsorbents such as zeolites that needs extensive studies. This study investigates the feasibility of sulfur compounds adsorption on improved nano zeolite existing in organic fuels and desorption of them from nano-adsorbent.Some properties of improved nano zeolite were analyzed to receive better sulfur compounds adsorption.<e...

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...
