MECS® XLP catalyst products have delivered reliable sulfuric acid converter performance for more than two decades. With the ribbed-ring design, the XLP portfolio combines low pressure drop, strong conversion performance, and long service life across a wide range of converter applications.
XLP-110 remains the industry standard, while XLP-310 builds on the proven XLP shape with higher activity for revamps, lower-pass optimization, and emissions reduction projects.
MECS® XLP ribbed-ring catalysts are engineered to perform reliably across the full range of converter conditions, from the demanding environment of the first pass to the high-SO₃, lower-SO₂ conditions in downstream beds.
XLP-110 combines proven durability with consistent conversion performance, delivering the pass-to-pass versatility plants rely on for stable, long-term operation.
XLP-310 features a higher-activity formulation designed for enhanced performance, especially in demanding high-SO₃ applications. This improved activity can help plants reduce emissions at a fixed catalyst loading or achieve target conversion with less total catalyst volume while preserving the same ribbed-ring geometry and low-pressure-drop advantages.
