Molecular Iodine—An Expedient Reagent for Oxidative Aromatization Reactions of α,β-Unsaturated Cyclic Compounds

Molecules, 2009
Prompted by the scant attention paid by published literature reviews to the applications of molecular iodine in oxidative aromatization reactions, we decided to review methods developed to-date involving iodine as an oxidant to promote aromatization of α,

Aromatization of n-hexane over H-ZSM-5: Influence of promoters and added gases

Applied Catalysis A: General, 1996
The influence of promoters such as ZnO, Ga2O3, Fe2O3 and Cr2O3 on the aromatization of n-hexane over H-ZSM-5 is reported. While ZnO and Ga2O3 increase aromatization, Fe2O3 and Cr2O3 decrease the aromatization.

Aromatization of n-octane over Pd/C catalysts

Fuel, 2013
Gas-phase aromatization of n-octane was investigated using Pd/C catalyst. The objectives were to: (1) determine the effects of temperature (400-600 °C), weight hourly space velocity (WHSV) (0.8-∞), and hydrogen to hydrocarbon molar ratio (MR) (0-6) on ...
