The Isomalk℠ family of technologies includes Isomalk-2 for C5-C6 isomerization, Isomalk-3 for C4 isomerization and Isomalk-4 for C7 paraffins isomerization. These processes are based on the use of mixed metal oxide (nonchlorinated) catalysts that operate at low temperatures, thus allowing refiners to enjoy high conversions to the key iso-components while maintaining prolonged catalyst service lifetimes, simple operation and resistance to process impurities.
