Sulfuric acid catalysts

Whether your plant produces sulfuric acid from elemental sulfur, spent sulfuric acid or sulfurous gases, our VK catalysts are a certain path to profitable production. They give you exceptionally high conversion rates and reliability, while keeping energy consumption low and ensuring compliance with environmental regulations.

The industry's widest range

Our VK range of sulfuric acid catalysts is the industry’s largest, encompassing standard, dust-protection, cesium-promoted and LEAP5™ designs. This enables us to give you the performance you’re looking for at the lowest possible cost – often by recommending a combination that is customized to meet your exact needs. The catalyst range also helps you eliminate converter performance bottlenecks, keep pressure drop, energy costs, and downtime to a minimum, and reduce scrubber costs to generate significant savings. All of this combined with unmatched high yields per invested dollar make the VK range your best choice for profitable operations – without exceeding limits on emission.
