COS hydrolysis catalyst

CKA-3 is a promoted alumina-based catalyst used for hydrolysis of carbonyl sulfide (COS).

The CKA-3 catalyst has a high activity even at low temperatures, which is essential for maximum conversion of COS, as the chemical equilibrium is favorable at low temperature.

Whether the end product is chemicals or power, hydrolysis of carbonyl sulfide can be used in some gasification based plants to provide a more optimal process layout.

In the COS hydrolysis reaction, the carbonyl sulfide is converted to hydrogen sulfide and carbon dioxide, which are easier to remove in the Acid Gas Removal (AGR) unit. As a result, the cost and size of the AGR can be reduced, which leads to significant savings.

COS hydrolysis in combination with sour shift

The SSK-10 sour shift catalyst is active towards COS hydrolysis, but the conversion will be limited by the equilibrium at the outlet of the sour shift section. If further reduction of the COS content is required, the CKA-3 catalyst can be used for treating the shifted gas and/or the gas bypassing the sour shift section.

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.
