Hydroisomerization of Renewable and Fossil n‐Alkanes over Bifunctional Dealuminated ZSM‐5 Catalysts

Schmutzler, Felix / Zschiesche, Christopher / Titus, Juliane / Poppitz, David / Freiding, Jens / Rakoczy, Rainer / Reitzmann, Andreas / Gläser, Roger

The hydroisomerization of two long‐chain n‐alkane mixtures was investigated over bifunctional Pt/H‐ZSM‐5 catalysts before and after dealumination of preshaped zeolite/binder pellets. The hydroisomerization over the dealuminated catalysts leads to more isomers and less cracking products. Consequently, higher ratios of multi‐ to mono‐branched isomerization products are formed as expected for large‐ rather than medium‐pore zeolites. This indicates a higher availability of space in the vicinity of the active sites and provides an attractive route to make medium‐pore zeolites suitable for upgrading higher boiling hydrocarbon feeds.
