    VK-701 LEAP5™

    LEAP5™ catalysts are specifically designed for oxidizing SO3-strong gases, and are ideal for use in the last passes in single-absorption plants or in the third pass in 3+1 and 3+2 double-absorption plants. Lower sulfur emissions, greater output or a balance of the two LEAP5™ catalysts enable you to...

    VK48

    VK48 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...

    VK59

    VK59 is a cesium-promoted catalyst optimized for medium to high strength SO2 gasses with continuous operation down to 370°C (700°F). A top layer of VK59 in the first pass makes it possible to accommodate high strength SO2 feed gas without exceeding the maximum outlet temperature of 630°C (1165°F)...

    VK69

    VK69 is designed specifically for the final pass(es) of double absorption plants. In the lean SO2 gas environment after the inter-pass absorption tower, the unique VK69 formulation offers unmatched high activity throughout the entire operating temperature range. This affords existing plants the...
