    A catalyst for high activity in SO2 gasses

    The VK-WSX formulation was developed to offer higher activity in SO2 gasses that are more than 90% converted.

    Typically VK-WSX is used in the last bed of a WSA converter. For this service, VK-WSX is more active than VK-WSA and even more active than cesium-promoted VK-WH catalyst. The high activity is the result of carefully optimizing the alkali-metal promoter content to the specific conditions in WSA converters in combination with a unique support material. VK-WSX is a non-cesium catalyst; yet it can operate effectively at temperatures as low as 370°C/700°F, enabling very high conversion rates to be reached.

    The high surface area of the 9 mm Daisy contributes to the high activity, and the high void fraction ensures a low pressure drop.

    Request Safety Data Sheet (SDS)

    Safety Data Sheets (SDS) also previous known as Material Safety Data Sheets (MSDS) are documents providing health and safety information on the handling of chemical products. These documents are only available for Haldor Topsoe's catalysts on request and can be requested in the form below.
