Rezel ISO-Z is comprised of noble metal, platinum, with zeolite support, it can be used for naphtha isomerization unit such as Penex to boost octane. It processes hydrotreated light naphtha, converts n-C5 and n-C6 to isopentane and di-methy butanes to boost octane.
As a zeolite-based catalyst, ISO-Z is suitable for in-situ regeneration.
The activity of zeolite based isomerization catalysts is lower compared to chlorinated alumina based catalysts. However, zeolite based catalysts are more robust and have a longer life expectancy when compared to chlorinated alumina based catalysts which are susceptible to poisoning by feed contaminants like oxygen (including water), nitrogen, and sulfur.
