Features Of Clariant Pyrotol Catalyst

  1. Highly selective for deep desulfurization of naphtha and reformate streams.

  2. Thermally stable under continuous operation at elevated temperatures up to 400 °C.

  3. Resistant to nitrogen and olefin poisoning, ensuring extended catalyst life.

  4. Low-pressure operation capability (1–30 bar), reducing energy consumption and equipment cost.

  5. Customizable pellet geometry and pore structure for optimized mass transfer and pressure drop control.

Typical Applications Of Clariant Pyrotol Catalyst

  1. Gasoline sulfur reduction in hydrotreating units prior to catalytic reforming.

  2. Naphtha pretreatment for platinum-based reforming catalysts.

  3. Production of ultra-low-sulfur gasoline (ULSG) meeting Tier 3 and Euro 6 specifications.

  4. Refinery integration with selective hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) processes.

  5. Feed purification for aromatic extraction and isomerization units.
