  • Testing of adsorbent performance in multiple cycles of sulphidation (H2S removal) and re-oxidation (regeneration).
  • Characterization of structural and chemical changes in the adsorbent during cycling.

    • Main Results:

    • Zn-Ti-O nanofibrous adsorbents maintained initial reactivity and sulfur removal capacity over multiple regeneration cycles.
    • Nanostructured sorbents exhibited rapid reaction rates, overcoming gas-transport limitations of conventional sorbents.
    • Efficient regeneration at the same temperature as sulphidation was achieved, preventing sorbent deterioration and reducing energy consumption.

    Conclusions:

    • Nanofibrous Zn-Ti-O adsorbents offer a durable and energy-efficient solution for hydrogen sulfide removal from fuels.
    • The unique nanostructure and phase stabilization contribute to the superior cyclic performance and regeneration.
    • This technology presents a promising advancement for cleaner fuel processing and industrial applications.
