A comparative study of n-butane conversion into aromatic hydrocarbons over ZSM-5
zeolite in H-form and modified with gallium and platinum at 530 °C in gas phase
(1 atm) and under supercritical conditions (190 atm) was carried out. The catalysts
demonstrate high activity, stability, and productivity under supercritical conditions. In
contrast to the gas phase process, modification of ZSM-5 zeolite with gallium and
platinum had no affect on the distribution of n-butane aromatization products in
supercritical conditions.
