<strong>SCX</strong>-<strong>2000</strong> – <strong>SUPER</strong> <strong>CESIUM</strong> <strong>CATALYST</strong><br />
SULFURIC ACID <strong>CATALYST</strong><br />
LOWER BED APPLICATIONS<br />
Monsanto Enviro-Chem Systems, Inc. offers an extremely active ribbed ring sulfuric<br />
acid catalyst specifically designed for the lower beds of the converter. This product is<br />
designated: “<strong>SCX</strong>-<strong>2000</strong>”.<br />
This novel catalyst is formulated specifically for lower pass applications with or<br />
without Interpass Absorption. The enhanced catalyst support structure of the <strong>SCX</strong>-<br />
<strong>2000</strong> generates the greatest conversion possible from the cesium-promoted catalyst<br />
while maintaining the same low screening losses that are experienced with the<br />
traditional Cs-110 ring catalyst and XCs-120 ribbed ring catalyst.<br />
BENEFITS<br />
• Higher plant production rates<br />
• Lower ignition temperature for faster plant start ups<br />
• Lower plant stack emission levels<br />

SULFURIC ACID <strong>CATALYST</strong><br />
UPPER AND LOWER BED APPLICATIONS<br />
Monsanto Enviro-Chem Systems, Inc. offers a ribbed ring shaped, cesium-promoted<br />
sulfuric acid catalyst specifically designed for pressure drop reduction in all beds of the<br />
converter. This product is designated: “XCs-120”.<br />
This product is designated XCs-120 (for use in all beds where appropriate); the “X”<br />
representing the eXtended surface area of these rings. Installation of the “XCs-120”<br />
catalyst will result in a pressure drop decrease in excess of 20 % to Cs-110 rings and<br />
approximately a 10 % reduction in pressure drop relative to Cs-120 rings.<br />
<strong>SCX</strong>-<strong>2000</strong> / XCs-120 Specifications:<br />
Nominal Ring Diameter “Point to Point” = 0.48 in (11.9 mm)<br />
Average Length = 0.38 – 0.55 in. (9.5 – 14.0 mm)<br />
Avg. Density = 1.1 – 1.3 lb/liter (0.50 – 0.60 kg/liter)<br />
