Overview

Investigates how saccharose passivation affects oxidation resistance and hydrodesulfurization activity in catalysts, suggesting improved performance under air exposure.

Key Points

  • The aim is to understand how saccharose passivation influences oxidation resistance and hydrodesulfurization activity of a sulfurized NiMo/Al2O3 catalyst.
  • Post-treated an oxidic NiMo/Al2O3 catalyst with saccharose passivation.
  • Examined the impact of saccharose amount and passivation temperature on oxidation resistance and dibenzothiophene hydrodesulfurization activity.
  • Analyzed the formation of carbonaceous deposits and their effects on metal interactions.
  • Saccharose passivation significantly enhances oxidation resistance of the sulfurized catalyst.
  • At 450 °C with a saccharose/Ni molar ratio of 1.5, oxidation degrees of Mo and Ni sulfides decreased by over 50% after air exposure.
  • Passivated catalysts showed only a 2.7% reduction in dibenzothiophene removal activity compared to a 12.9% reduction in unpassivated catalysts.
