Isomalk-2 - A low-temperature light naphtha isomerization process

Isomalk-2 is a low-temperature isomerization technology that has been commercially proven in grassroots applications, revamps of semi-regenerative reforming units, and replacement of other isomerization technologies. This flexible process utilizes a robust platinum-containing mixed metal oxide SI-2 catalyst that works effectively at the low temperatures of 120-140°C (250-285°F), while delivering great stability against the influence of catalytic poisons. Isomalk-2 is a competitive alternative to the three most commonly used light gasoline isomerization processes: zeolite, chlorinated aluminum oxide and sulfated zirconium oxide catalysts, applicable for simple replacement of these catalyst types. This technology has been commercialized in all possible modes of configuration. By applying the full recycle configuration, an isomerate with a 92.5 RON value has been achieved in a world-scale reference unit.
