Scholarcy highlights

  • SBA-15 and ZrO2 containing SBA-15 mesoporous materials were prepared by direct and post-synthesis methods
  • Characterization using low angle XRD, pore size distribution, CO2 chemisorption indicate that hexagonal mesoporous structure is retained even after ZrO2 addition
  • CoMo and NiMo catalysts prepared using these supports were examined by XRD, oxygen chemisorption, temperature programmed reduction
  • Oxygen chemisorption and TPR hydrogen consumption indicated that the molybdenum dispersion and anion vacancies, and catalytic activities are significantly influenced by ZrO2 content in Zr-SBA-15
  • A comparison indicated that TiO2-SBA-15, ZrO2-SBA-15 supported CoMo catalysts show higher activities for hydrodesulfurization
