is an alumina-based catalyst for the skeletal isomerization of C4 and C5 olefins cuts. The isomerization process produces iso-olefins used as an intermediate in MTBE and TAME synthesis.
High yields of iso-olefins are obtained along with high selectivity at moderate temperatures.
IS 463 is a robust catalyst, very easy to operate and easily regenerable by an ordinary coke burn-off step. Its high resistance to attrition allows its use in a continuous catalyst regeneration process.
Moreover IS 463 offers a high resistance to poisoning by sulfur, nitrogen, oxygenates and diolefins.
