Abstract

Ethane aromatization on gallium-and platinum-modified pentasil zeolites (ZSM-5) with different framework constitutions was studied. The optimal zeolite composition and reaction conditions were determined and the synergistic effect of the promoters was revealed. The dependence of the catalyst activity on the SiO2/Al2O3 molar ratio was established. The highest yield of aromatic hydrocarbons (∼30%) and the highest selectivity for their formation from ethane (∼63%) were attained on the (2%Ga–0.3%Pt)/HZSM-5 bimetallic catalyst having SiO2/Al2O3 = 30.
