    Sulfuric acid | Sulfur dioxide oxidation

    The catalytic SO2 converter is the heart of the sulfuric acid plant and the quality and characteristics of the selected catalysts are crucial to a reliable and energy-efficient operation.

    The catalyst properties are influenced by the chemical composition, the physical properties including the nature of the support material and the manufacturing process. Topsoe VK catalysts are uniquely balanced to combine high and stable activity, robustness, low-pressure drop and a long service life.

    Over the years Topsoe has brought major product breakthroughs to the market, providing the industry with new catalysts for more energy-efficient operation, lower SO2 emissions and higher production rates.

    Topsoe’s VK series comprises five different formulations in a variety of sizes and shapes, effectively covering all operating conditions in any sulfuric acid plant.
