TK-441 SiliconTrap™

High silicon trapping capacity

High HDS and HDN activity

Pure alumina, hight density

Recommended for diolefin saturation

A catalyst for desulfurization of coker naphtha

Replacing TK-431, TK-441 SiliconTrap™ is a high surface area catalyst for desulfurization of coker naphthas containing up to 11 ppm silicon. The metal loading of TK-441 SiliconTrap™ gives this catalyst a high hydrodesulfurization (HDS) and a high hydrodenitrogenation (HDN) activity.

The pure alumina carrier used for preparation of TK-441 SiliconTrap™ ensures that this catalyst has a very high density and a higher surface area compared with other commercially available coker naphtha catalysts. As a result, TK-441 SiliconTrap™ has a very high surface area per reactor volume, which results in a very high silicon pick-up capacity and, thus, a prolonged cycle length.

A catalyst for diolefin saturation

TK-441 SiliconTrap™ is also the recommended catalyst for diolefin saturation. Diolefin hydrotreating is best carried out in a separate guard reactor operating at low operating temperature (180–220°C).

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.
