A new highly active, low density isomerization catalyst has been developed by Axens and Akzo Nobel Catalysts, b.v. for the conversion of low octane light naphtha into high octane products. This catalyst, ATIS-2L, provides the same superior activity as Akzo Nobel’s proven AT-20 isomerization catalyst but has a much lower density. When new fuel specifications and the total cost to reload a reactor are considered the benefits of high activity and low density catalyst result in greater return on investment. The exceptional performance of ATIS-2L has been demonstrated in pilot plant tests and in commercial operation for almost one year. Both isomerate yield and octane have been improved with this new break through catalyst. Several isomerization process options are available and all benefit from the new ATIS-2L catalyst. Revamp options to enhance the octane performance of existing units are shown to be attractive and cost effective.
