Aromatization of Propylene on Pt-Cu /?-Al2O3 Nano-Catalyst

Abstract

Aromatization of propylene was carried out on Pt-Cu/ ?-Al₂O₃ bimetal catalyst at a temperature of 460 ± 60^oC and the effectiveness of the catalyst was measured using the Gas to Liquid (GTL) product rate per single feed run. The observed mechanism was used to propose a kinetic that can be used to quantify the viability of the nano-catalyst presented here. From the kinetic analysis it was observed that adsorption of hexene-1 was responsible for isomerization reaction that produced methyl-cyclopentene. The methyl-cyclopentadiene served as electron pivotal at the catalyst centre where Pt-Cu/?-Al₂O₃ was responsible for ring opening and subsequent cyclic formation and isomerization that produced benzene the final product with an observed suppression of cracked products.
