    VK-WH

    VK-WH is a cesium-promoted catalyst designed for continuous operation down to 370°C/700°F in medium- to high-strength SO2+SO3 gasses. A top-layer of VK-WH can significantly improve operating flexibility by widening the bed temperature control window, especially in plants struggling with fluctuating...

    VK-WL

    VK-WL is a cesium-promoted catalyst designed for continuous operation down to 370°C/700°F in lean SO2+SO3 gasses (less than approximately 2 mole%). At these conditions, VK-WL offers unmatched high activity throughout the entire operating temperature range. The very high activity provides the...

    VK-WSA

    The VK-WSA formulation offers excellent activity over a wide range of operating conditions and can be used in any bed of a WSA or WSA-DC converter. VK-WSA is available in the 12 mm Daisy shape and as a dust-protection catalyst in the large 25 mm Daisy shape. 12 mm Daisy: improved energy efficiency...
