VK48 Catalyst

Emission control

High vanadium catalyst version.

Optimized for lower pass service.

Enhanced activity in high SO₃ environments.

Efficient shapes for gas distribution.

A catalyst for low pass service where large amounts of SO₃is present

VK48 catalyst is a high vanadium version of the standard all-round VK38 catalyst.

The catalyst composition is specifically formulated for lower pass service, particularly where the process gas contains large amounts of SO₃. The conversion ratio of SO₂ affects the balance between the active vanadium species in the catalyst.

An optimized ratio of the alkali-metal promoters enables an increased vanadium content in VK48, resulting in a considerably enhanced activity. In high SO₃ gas environments, such as the lower passes of single absorption plants, or the third pass of a 3:1 double absorption plant, VK48 offers a significant performance advantage.

12 mm Daisy

12 mm Daisy : improved energy efficiency throughout the operating cycle due to low initial pressure drop; 6 mm cylinder and 10 mm ring: ensure an even gas distribution in applications with low gas velocity converters.

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.
