TK-461 SiliconTrap™ Catalyst

Advanced silicon guard catalyst for coker naphtha hydrotreating

As a part of our third-generation silicon management catalysts for refineries, TK-461 SiliconTrap™ offers outstanding performance in coker naphtha hydrotreating (HDT).

TK-461 SiliconTrap™ combines a high 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-461 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.

Key benefits of TK-461 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.
