TK-467 SiliconTrap™ Catalyst

High-performance silicon guard catalyst

TK-467 SiliconTrap™ is designed for first-stage coker naphtha hydrotreating and offers refineries outstanding silicon capture and reliable sulfur and nitrogen removal.

TK-467 SiliconTrap™ combines a medium HDS/HDN NiMo formulation with advanced preparation technology to deliver a higher alumina surface area, enabling exceptional silicon pick-up per volume and outstanding sulfur and nitrogen removal over earlier generations.

TK-467 SiliconTrap™ enables refineries to extend unit cycle length, process a more severe feedstock and increase the reliability of downstream units, such as reforming and isomerization.

The medium hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) activity of TK-467 SiliconTrap enables safe and stable operations.

Key benefits of TK-467 SiliconTrap

• Outstanding silicon pick-up per volume basis

• Enhanced HDS and HDN activity compared with earlier generations

• Extended cycle length for fewer catalyst change-outs

• Cost-effective protection of downstream catalysts

• True alumina surface area delivering effective silicon uptake (no silicon from manufacture)

• Strong cost-to-benefit efficiency

The TK-400 SiliconTrap™ series

The TK-400 SiliconTrap™ catalysts series have played a key role in the coker naphtha market for more than 25 years. The new-generation TK-461 SiliconTrap™ and TK-467 SiliconTrap™ catalysts were launched in late 2024, offering a further increased surface area per volume.
