TK-461 SiliconTrap™ Catalyst

Conventional fuels

Improves silicon pick-up per volume basis.

Extended unit cycle length due to enhanced HDN and HDS activity.

A third-generation silicon management 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.

Sustainable Aviation Fuel

As a direct replacement for conventional fuel, SAF is an easy decarbonization measure that will help the aviation industry decarbonize immediately.

Power-to-X

To lower emissions in energy-intensive industries and long-distance transportation, we need technologies such as electrolysis in Power-to-X processes technology.

Renewable fuels

Renewable fuels will help us decarbonize heavy-duty transportation, and we’ll need proven technologies for their production. Luckily, these already exist.

Hydrogen

The abundance of hydrogen coupled with its potential for sustainable methods of production, positions it as a promising solution in the global energy transition. 

Ammonia

Ammonia is considered a gamechanger in decarbonizing the maritime industry and other energy-intensive industries where direct electrification is not an option.
