Catalyst

The low-temperature isomerization catalyst is based on sulfated zirconia and is primarily used in refinery processes

within the isomerization units, applied to lighter cuts of naphtha and gasoline.

Advantages and Features:

• Resistant to the presence of sulfur, nitrogen, and water in the feed, minimizing the need for feed purification and
• having no impact on catalyst performance or the final product.
• Catalyst activity and conversion rate are comparable to conventional feeds with chlorinated catalysts based on
• alumina oxide.
•  No need for a chloriding agent (perchloroethylene) to stabilize catalyst activity.
• Very high selectivity, which reduces hydrogen consumption and lowers low-octane compounds in refinery feeds.
• Resistant to feed rate changes (range of 0.5 to 3 h⁻¹).
• Catalyst can be regenerated after the initial usage period (5 to 6 years) and reused for an additional 3 to 4 years
• without any loss in activity.
• The catalyst’s useful lifespan is estimated to be around 10–12 years.
