“Nanowire catalysts for ultra-deep hydro-desulfurization and aromatic hydrogenation”

摘要: Abstract Here, we report high performance catalysts designed using nanowire supports. Specifically, nickel clusters supported on Zinc Oxide (ZnO) nanowires and γ-alumina found to be highly active for ultra-deep desulfurization aromatic hydrogenation of diesel. They were also gasoline kerosene. The reduced sulfur from diesel, gasoline, kerosene fuels containing as approximately 200 ppm less than 1 ppm with sustained activity over testing periods 100–150 h. feed contained some the most difficult remove compounds such 4-methyldibenzothiophene (MDBT), 4,6-dimethyldibenzothiophene (DMDBT). In addition towards desulfurization, these have shown saturate/hydrogenate aromatics in diesel at moderate reaction conditions (30 bar, 290 °C, LHSV 2.2 h−1). catalytic site was determined a super Ni rich NixZny phase which seemed remain essentially free during reaction. regenerated catalyst showed reasonable toward gasoline.
