Pt/Chlorided-alumina type catalysts used for light naphtha Isomerization processes such as UOP’s Penex™ process are non-regenerable. They are deactivated by contaminants, primarily oxygenated compounds, such as CO and water. These types of catalysts (e.g. UOP I-82 Isomerization catalyst) replaced other regenerable types such as older generation zeolitic types (e.g. UOP HS-10 Isomerization catalyst). The newer generation chloride-alumina catalysts provide the highest activity, conversion, and octane number compared to other catalyst types. With proper care and feed treatment, UOP has catalyst loads operating in excess of twenty years. Should a refiner desire a catalyst capable of in-situ regeneration, UOP also offers it’s UOP Par-Isom™ process and corresponding PI-244 Isomerization catalyst with over 20 units operating world-wide.

Such catalysts cannot be regenerated in situ. Zeolite based light naphtha isomerization catalysts may be regenerated in situ
