Selective Oxidation Catalysts for Maleic Anhydride (MA) Production
SynDane™ Series
Edition Date :
February 06, 2026
SynDane™ catalysts enable cost-efficient production of maleic anhydride via partial oxidation of n-butane in fixed-bed tubular reactors. Their superior yield and selectivity greatly reduce by-product formation and downstream polymerization, thus minimizing downtime of maleic anhydride plants.
Product Information
Benefits
- Higher selectivity and maleic anhydride yield due to innovative microstructure and chemical composition
- Proprietary double-alpha shape of some SynDane™ catalysts reduces pressure drop, thus maximizing energy and process efficiency
- Excellent operating stability ensures long catalyst lifetime
- Reduced formation of undesired by-products (e.g. acrylic acid, acetic acid) decreases plant downtime for equipment cleaning
- In plants with water-based backend technology: also fewer process water changes
- Operation at high n-butane load and space velocity ensures efficient maleic anhydride production
